+
+**Graph-Conditioned On-Policy Agent Distillation from Off-the-Shelf Teachers**
+
+[Paper](https://arxiv.org/abs/2609.37522) · [Code and evaluation instructions](https://github.com/hanyi2021/GC_OPD)
+
+This collection contains eight BF16 models: GC-OPD and GC-OPD+GA for ScienceWorld 1.7B/4B, ALFWorld 1.7B and WebShop 0.8B. GA uses planner/oracle executions to augment the training graph.
+
+| Environment | Student | GC-OPD | GC-OPD+GA |
+|---|---|---|---|
+| ScienceWorld | Qwen3-1.7B | [46.18%](gc-opd-scienceworld-qwen3-1.7b/) | [53.61%](gc-opd-scienceworld-qwen3-1.7b-ga/) |
+| ScienceWorld | Qwen3-4B | [48.78%](gc-opd-scienceworld-qwen3-4b/) | [54.68%](gc-opd-scienceworld-qwen3-4b-ga/) |
+| ALFWorld | Qwen3-1.7B | [85.26%](gc-opd-alfworld-qwen3-1.7b/) | [93.47%](gc-opd-alfworld-qwen3-1.7b-ga/) |
+| WebShop | Qwen3.5-0.8B | [37.65%](gc-opd-webshop-qwen3.5-0.8b/) | [39.90%](gc-opd-webshop-qwen3.5-0.8b-ga/) |
+
+Success rates are the paper's four-seed means for the corresponding checkpoints; ALFWorld reports Unseen success. Individual model cards contain the full results and inference settings.
+
+## Model files
+
+Each model is stored in the subdirectory linked above and includes BF16 weights, configuration, tokenizer and chat template. Individual model cards describe the corresponding checkpoint and inference settings.
+
+## Download and evaluate
+
+Download the desired model subdirectory with the Hugging Face CLI. Set `REPO_ID` to this repository's `owner/name`:
+
+```bash
+REPO_ID="owner/GC-OPD"
+MODEL="gc-opd-scienceworld-qwen3-1.7b"
+hf download "$REPO_ID" --include "${MODEL}/*" --local-dir ./models
+```
+
+Pass `./models/${MODEL}` to `--model` in the matching [ScienceWorld, ALFWorld or WebShop evaluation command](https://github.com/hanyi2021/GC_OPD#evaluate-an-existing-model). Use the supplied tokenizer and chat template with the environment-specific prompts and evaluation settings in the code.

+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing

+# GC-OPD + GA ALFWorld Qwen3-1.7B — BF16
+
+Paper: [arXiv:2609.37522](https://arxiv.org/abs/2609.37522).
+
+BF16 export of checkpoint **C209** from *Graph-Conditioned On-Policy Agent Distillation from Off-the-Shelf Teachers*. This student was trained with graph-conditioned on-policy distillation from an original Qwen3-32B teacher and planner-augmented training graphs (GA). The added planner sources were replay verified and limited to 30 decisions. Inference uses the student policy with the ALFWorld task, observation, admissible actions and recent history.
+
+All 310 stored floating-point tensors are BF16. Every tensor was checked bit-for-bit against the source checkpoint cast to BF16, with unchanged names and shapes and no nonfinite values. The original source weights were retained separately.
+
+## Paper results
+
+| Split | Tasks per seed | Success (%) |
+|---|---:|---:|
+| Seen | 140 | 96.07 ± 0.92 |
+| Unseen | 134 | 93.47 ± 0.71 |
+
+The table reports the corresponding source checkpoint's results from the paper: mean ± sample standard deviation over four inference seeds.
+
+## Use with the public code
+
+Code and installation: [hanyi2021/GC_OPD](https://github.com/hanyi2021/GC_OPD).
+
+From the public GC-OPD code repository root, with the official ALFWorld/TextWorld environment installed:
+
+```bash
+CUDA_VISIBLE_DEVICES=0 python -m gcopd.alfworld.evaluate \
+  --model /path/to/gc-opd-alfworld-qwen3-1.7b-ga \
+  --data-root /path/to/alfworld/json_2.1.1 \
+  --env-python /path/to/alfworld-env/bin/python \
+  --backend vllm --reps 0 --output /path/to/new-evaluation
+```
+
+The benchmark wrapper uses a fresh single-user H5 context, up to 30 decisions, a 512-token response cap, temperature 0.4, top-p 1 and no top-k restriction. It disables the model's separate thinking chat mode while retaining the requested thought/action response format. Use the wrapper's explicit sampling parameters for benchmark evaluation.
+
+The configuration retains matching legacy `rope_theta` and modern `rope_parameters` with theta **1,000,000**. Tokenizer and chat-template payloads are preserved. Teacher weights, training graphs and optimizer state are unnecessary for inference and are not included.

+
+      You may add Your own copyright statement to Your modifications and

+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify

+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade

+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,

+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.

+# GC-OPD ALFWorld Qwen3-1.7B — BF16
+
+Paper: [arXiv:2609.37522](https://arxiv.org/abs/2609.37522).
+
+BF16 export of checkpoint **C196** from *Graph-Conditioned On-Policy Agent Distillation from Off-the-Shelf Teachers*. This student was trained with graph-conditioned on-policy distillation from an original Qwen3-32B teacher. Inference uses the student policy with the ALFWorld task, observation, admissible actions and recent history.
+
+All 310 stored floating-point tensors are BF16. Every tensor was checked bit-for-bit against the source checkpoint cast to BF16, with unchanged names and shapes and no nonfinite values. The original source weights were retained separately.
+
+## Paper results
+
+| Split | Tasks per seed | Success (%) |
+|---|---:|---:|
+| Seen | 140 | 91.61 ± 0.68 |
+| Unseen | 134 | 85.26 ± 0.71 |
+
+The table reports the corresponding source checkpoint's results from the paper: mean ± sample standard deviation over four inference seeds.
+
+## Use with the public code
+
+Code and installation: [hanyi2021/GC_OPD](https://github.com/hanyi2021/GC_OPD).
+
+From the public GC-OPD code repository root, with the official ALFWorld/TextWorld environment installed:
+
+```bash
+CUDA_VISIBLE_DEVICES=0 python -m gcopd.alfworld.evaluate \
+  --model /path/to/gc-opd-alfworld-qwen3-1.7b \
+  --data-root /path/to/alfworld/json_2.1.1 \
+  --env-python /path/to/alfworld-env/bin/python \
+  --backend vllm --reps 0 --output /path/to/new-evaluation
+```
+
+The benchmark wrapper uses a fresh single-user H5 context, up to 30 decisions, a 512-token response cap, temperature 0.4, top-p 1 and no top-k restriction. It disables the model's separate thinking chat mode while retaining the requested thought/action response format. Use the wrapper's explicit sampling parameters for benchmark evaluation.
+
+The configuration retains matching legacy `rope_theta` and modern `rope_parameters` with theta **1,000,000**. Tokenizer and chat-template payloads are preserved. Teacher weights, training graphs and optimizer state are unnecessary for inference and are not included.

+# Attribution and changes
+
+This model derives from [Qwen/Qwen3-1.7B](https://huggingface.co/Qwen/Qwen3-1.7B), developed by the Qwen team. The model architecture and tokenizer are attributed to Qwen. The included LICENSE preserves the upstream Apache License, Version 2.0.
+
+GC-OPD changes the model weights through on-policy agent distillation and graph-conditioned training. The +GA variant additionally uses planner records to augment the training graph. This release stores floating-point tensors in BF16 and preserves non-floating tensors. Tokenizer vocabulary and chat-template content are preserved. Configuration updates retain equivalent RoPE and special-token settings across Transformers versions.
+
+The derived weights are released under Apache-2.0. This work does not imply endorsement by Qwen.

+# GC-OPD + GA ScienceWorld Qwen3-1.7B
+
+Paper: [arXiv:2609.37522](https://arxiv.org/abs/2609.37522).
+
+A ScienceWorld student trained with Graph-Conditioned On-Policy Distillation (GC-OPD). This +GA variant augments the training graph with executed ScienceWorld gold-path planner records and their observed outcomes. This 1.7B recipe also labels the final response when an episode ends naturally with a finite negative score; horizon and technical stops are excluded. The graph and planner are training resources; evaluation uses the student policy.
+
+This checkpoint accompanies *Graph-Conditioned On-Policy Agent Distillation from Off-the-Shelf Teachers*.
+
+## Paper reference results
+
+| Split | Tasks per repeat | Success (%) |
+|---|---:|---:|
+| ScienceWorld test | 1661 | 53.61 ± 0.48 |
+
+Selected checkpoint: **C235**. The table reports mean ± sample standard deviation across four inference repeats of one trained checkpoint. These are the paper's reference measurements.
+
+## Inference
+
+Code and installation: [hanyi2021/GC_OPD](https://github.com/hanyi2021/GC_OPD).
+
+Use this model directory with the ScienceWorld evaluator in the GC-OPD public code. No teacher, graph, or planner is required at evaluation time.
+
+The paper protocol uses temperature **0.4**, top-p **1.0**, no top-k restriction, `enable_thinking=False`, and at most **512 generated tokens per decision**. Each task permits at most **30 decisions**, with a history window of the latest **five decisions**. Use the supplied tokenizer and chat template.
+
+Weights are stored as **BF16** in a single `model.safetensors` file. With Transformers 5, load with `dtype=torch.bfloat16`. The model configuration preserves matching legacy and modern RoPE fields with theta **1,000,000** for Transformers compatibility.
+
+This directory contains inference weights, configuration, tokenizer, and chat template. Training optimizer state is not included.

+# Attribution and changes
+
+This model derives from [Qwen/Qwen3-1.7B](https://huggingface.co/Qwen/Qwen3-1.7B), developed by the Qwen team. The model architecture and tokenizer are attributed to Qwen. The included LICENSE preserves the upstream Apache License, Version 2.0.
+
+GC-OPD changes the model weights through on-policy agent distillation and graph-conditioned training. This release stores floating-point tensors in BF16 and preserves non-floating tensors. Tokenizer vocabulary and chat-template content are preserved. Configuration updates retain equivalent RoPE and special-token settings across Transformers versions.
+
+The derived weights are released under Apache-2.0. This work does not imply endorsement by Qwen.

+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of

+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing

+# GC-OPD ScienceWorld Qwen3-1.7B
+
+Paper: [arXiv:2609.37522](https://arxiv.org/abs/2609.37522).
+
+A ScienceWorld student trained with Graph-Conditioned On-Policy Distillation (GC-OPD). This is the ordinary GC-OPD variant, without planner-based graph augmentation. The graph and planner are training resources; evaluation uses the student policy.
+
+This checkpoint accompanies *Graph-Conditioned On-Policy Agent Distillation from Off-the-Shelf Teachers*.
+
+## Paper reference results
+
+| Split | Tasks per repeat | Success (%) |
+|---|---:|---:|
+| ScienceWorld test | 1661 | 46.18 ± 1.13 |
+
+Selected checkpoint: **C140**. The table reports mean ± sample standard deviation across four inference repeats of one trained checkpoint. These are the paper's reference measurements.
+
+## Inference
+
+Code and installation: [hanyi2021/GC_OPD](https://github.com/hanyi2021/GC_OPD).
+
+Use this model directory with the ScienceWorld evaluator in the GC-OPD public code. No teacher, graph, or planner is required at evaluation time.
+
+The paper protocol uses temperature **0.4**, top-p **1.0**, no top-k restriction, `enable_thinking=False`, and at most **512 generated tokens per decision**. Each task permits at most **30 decisions**, with a history window of the latest **five decisions**. Use the supplied tokenizer and chat template.
+
+Weights are stored as **BF16** in a single `model.safetensors` file. With Transformers 5, load with `dtype=torch.bfloat16`. The model configuration preserves matching legacy and modern RoPE fields with theta **1,000,000** for Transformers compatibility.
+
+This directory contains inference weights, configuration, tokenizer, and chat template. Training optimizer state is not included.

+# Attribution and changes
+
+This model derives from [Qwen/Qwen3-4B](https://huggingface.co/Qwen/Qwen3-4B), developed by the Qwen team. The model architecture and tokenizer are attributed to Qwen. The included LICENSE preserves the upstream Apache License, Version 2.0.
+
+GC-OPD changes the model weights through on-policy agent distillation and graph-conditioned training. The +GA variant additionally uses planner records to augment the training graph. This release stores floating-point tensors in BF16 and preserves non-floating tensors. Tokenizer vocabulary and chat-template content are preserved. Configuration updates retain equivalent RoPE and special-token settings across Transformers versions.
+
+The derived weights are released under Apache-2.0. This work does not imply endorsement by Qwen.

+# GC-OPD + GA ScienceWorld Qwen3-4B
+
+Paper: [arXiv:2609.37522](https://arxiv.org/abs/2609.37522).
+
+A ScienceWorld student trained with Graph-Conditioned On-Policy Distillation (GC-OPD). This +GA variant augments the training graph with executed ScienceWorld gold-path planner records and their observed outcomes. The graph and planner are training resources; evaluation uses the student policy.
+
+This checkpoint accompanies *Graph-Conditioned On-Policy Agent Distillation from Off-the-Shelf Teachers*.
+
+## Paper reference results
+
+| Split | Tasks per repeat | Success (%) |
+|---|---:|---:|
+| ScienceWorld test | 1661 | 54.68 ± 0.62 |
+
+Selected checkpoint: **C190**. The table reports mean ± sample standard deviation across four inference repeats of one trained checkpoint. These are the paper's reference measurements.
+
+## Inference
+
+Code and installation: [hanyi2021/GC_OPD](https://github.com/hanyi2021/GC_OPD).
+
+Use this model directory with the ScienceWorld evaluator in the GC-OPD public code. No teacher, graph, or planner is required at evaluation time.
+
+The paper protocol uses temperature **0.4**, top-p **1.0**, no top-k restriction, `enable_thinking=False`, and at most **512 generated tokens per decision**. Each task permits at most **30 decisions**, with a history window of the latest **five decisions**. Use the supplied tokenizer and chat template.
+
+Weights are stored as **BF16** in a single `model.safetensors` file. With Transformers 5, load with `dtype=torch.bfloat16`. The model configuration preserves matching legacy and modern RoPE fields with theta **1,000,000** for Transformers compatibility.
+
+This directory contains inference weights, configuration, tokenizer, and chat template. Training optimizer state is not included.

+# Attribution and changes
+
+This model derives from [Qwen/Qwen3-4B](https://huggingface.co/Qwen/Qwen3-4B), developed by the Qwen team. The model architecture and tokenizer are attributed to Qwen. The included LICENSE preserves the upstream Apache License, Version 2.0.
+
+GC-OPD changes the model weights through on-policy agent distillation and graph-conditioned training. This release stores floating-point tensors in BF16 and preserves non-floating tensors. Tokenizer vocabulary and chat-template content are preserved. Configuration updates retain equivalent RoPE and special-token settings across Transformers versions.
+
+The derived weights are released under Apache-2.0. This work does not imply endorsement by Qwen.

+# GC-OPD ScienceWorld Qwen3-4B
+
+Paper: [arXiv:2609.37522](https://arxiv.org/abs/2609.37522).
+
+A ScienceWorld student trained with Graph-Conditioned On-Policy Distillation (GC-OPD). This is the ordinary GC-OPD variant, without planner-based graph augmentation. The graph and planner are training resources; evaluation uses the student policy.
+
+This checkpoint accompanies *Graph-Conditioned On-Policy Agent Distillation from Off-the-Shelf Teachers*.
+
+## Paper reference results
+
+| Split | Tasks per repeat | Success (%) |
+|---|---:|---:|
+| ScienceWorld test | 1661 | 48.78 ± 0.58 |
+
+Selected checkpoint: **C190**. The table reports mean ± sample standard deviation across four inference repeats of one trained checkpoint. These are the paper's reference measurements.
+
+## Inference
+
+Code and installation: [hanyi2021/GC_OPD](https://github.com/hanyi2021/GC_OPD).
+
+Use this model directory with the ScienceWorld evaluator in the GC-OPD public code. No teacher, graph, or planner is required at evaluation time.
+
+The paper protocol uses temperature **0.4**, top-p **1.0**, no top-k restriction, `enable_thinking=False`, and at most **512 generated tokens per decision**. Each task permits at most **30 decisions**, with a history window of the latest **five decisions**. Use the supplied tokenizer and chat template.
+
+Weights are stored as **BF16** in a single `model.safetensors` file. With Transformers 5, load with `dtype=torch.bfloat16`. The model configuration preserves matching legacy and modern RoPE fields with theta **1,000,000** for Transformers compatibility.
+
+This directory contains inference weights, configuration, tokenizer, and chat template. Training optimizer state is not included.

+      transformation or translation of a Source form, including but
+      not limited to compiled object code, generated documentation,
+      and conversions to other media types.

+      Object form, made available under the License, as indicated by a
+      copyright notice that is included in or attached to the work
+      (an example is provided in the Appendix below).
+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain

+      the Work and Derivative Works thereof.
+
+      "Contribution" shall mean any work of authorship, including
+      the original version of the Work and any modifications or additions
+      to that Work or Derivative Works thereof, that is intentionally

+
+      "Contributor" shall mean Licensor and any individual or Legal Entity

+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the

+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+

+# GC-OPD + GA — WebShop — Qwen3.5-0.8B
+
+Paper: [arXiv:2609.37522](https://arxiv.org/abs/2609.37522).
+
+A WebShop student from *Graph-Conditioned On-Policy Agent Distillation from Off-the-Shelf Teachers*.
+
+The student is initialized from Qwen3.5-0.8B and trained with a frozen Qwen3.8-27B scoring teacher. The GA variant adds executed training-task oracle records to the graph source library. Inference uses the student alone.
+
+## Weights and inference
+
+Code and installation: [hanyi2021/GC_OPD](https://github.com/hanyi2021/GC_OPD).
+
+Weights are stored in **BF16**. Use the matching GC-OPD code release for the WebShop prompt, action parser and environment protocol. The model is evaluated as a text agent.
+
+Evaluation uses temperature 0.4, top-p 1.0, no top-k restriction, thinking disabled, H2 history, a 2,048-token response cap and a 15-decision horizon. The official test set contains goal IDs 0–499.
+
+From the code repository root, with the benchmark environment service running:
+
+```bash
+python -m gcopd.webshop.evaluate \
+  --model /path/to/gc-opd-webshop-qwen3.5-0.8b-ga \
+  --env-url http://127.0.0.1:8300 \
+  --reps 0 \
+  --backend vllm --device cuda \
+  --output runs/gc-opd-webshop-qwen3.5-0.8b-ga/rep0

+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain

+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,

+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and

+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.

+# GC-OPD — WebShop — Qwen3.5-0.8B
+
+Paper: [arXiv:2609.37522](https://arxiv.org/abs/2609.37522).
+
+A WebShop student from *Graph-Conditioned On-Policy Agent Distillation from Off-the-Shelf Teachers*.
+
+The student is initialized from Qwen3.5-0.8B and trained with a frozen Qwen3.8-27B scoring teacher. This variant uses teacher execution records without planner/oracle graph augmentation. Inference uses the student alone.
+
+## Weights and inference
+
+Code and installation: [hanyi2021/GC_OPD](https://github.com/hanyi2021/GC_OPD).
+
+Weights are stored in **BF16**. Use the matching GC-OPD code release for the WebShop prompt, action parser and environment protocol. The model is evaluated as a text agent.
+
+Evaluation uses temperature 0.4, top-p 1.0, no top-k restriction, thinking disabled, H2 history, a 2,048-token response cap and a 15-decision horizon. The official test set contains goal IDs 0–499.
+
+From the code repository root, with the benchmark environment service running:
+
+```bash
+python -m gcopd.webshop.evaluate \
+  --model /path/to/gc-opd-webshop-qwen3.5-0.8b \
+  --env-url http://127.0.0.1:8300 \
+  --reps 0 \
+  --backend vllm --device cuda \
+  --output runs/gc-opd-webshop-qwen3.5-0.8b/rep0
+```
+
+## Paper results
+
+Selected checkpoint: **C100**. The table reports this source checkpoint's results from the paper on the official 500-task test set: mean ± sample standard deviation across four inference seeds.
+
+| Success (%) | Score (×100) | Mean decisions |
+|---:|---:|---:|
+| 37.65 ± 0.93 | 60.14 ± 1.06 | 6.66 ± 0.04 |
