| # Vulcan-1-Coder (GGUF) | |
|  | |
| Results used no tools and a benchmarking harness. Also quantised to q8. | |
| A 2.5B coding and reasoning model built by using Integer Space Artificial Selection on **[CherryPit 1.2](https://huggingface.co/DRUPEs/CherryPit-1.2-2B)**, | |
| an already excellent model made by the team at DRUPEs. This model was generated and tested as a `.gguf`. Details | |
| of the method will be published later and released for all. I'm working hard to put everything together. | |
| **Made in an afternoon.** Vulcan was produced in a single afternoon along with about 30 other models (12 in its | |
| class), all generated and tested in integer space, on a laptop with a **6 GB VRAM** GPU, using only my own tools. | |
| No training runs, no cluster. | |
| Every run, lasting just a few hours, resulted in success. The techique can work for all types of models. It's a data-led technique where the training is | |
| squeezed out rather than training it on more data. If the information exists in the model, we select for it. | |
| Named after Vulcan, the Roman god of fire and the forge, the smith who crafts tools for the gods. | |
| **Safetensors version: coming soon.** | |
| ## Files | |
| | file | quant | size | notes | | |
| |---|---|---|---| | |
| | `Vulcan-1-Coder-Q4_K_M-league.gguf` | Q4_K_M | 1.56 GB | the exact weights that won the selection league | | |
| ## Results | |
| Notes: This model has not been fully tested or trained further after selection. It may have flaws or issues, for example one time it sent a bunch of symbols. | |
| But generally it scores high. All benchmarks are with no tools AND quantised. | |
| ### AIME 2025 | |
| Run 1: | |
| 21 / 30 = 70.0% with thinking on, up to 24K tokens, temperature 1.0, 1 sample, Q8_0. Benchmarking harness. No tools. | |
| Per-problem results: Will add soon to a site I'm building. | |
|  | |
| ### AIME 2026 | |
| Notes: Although at this level, it could be noise, I wonder if selecting for the model at Q4_K_M found a model that's best at Q4_K_M. I'll get access to a better GPU soon and test. | |
| Run 1: | |
| **23 / 30 = 76.7%** with thinking on, up to 24K tokens, temperature 1.0, 1 sample, Q4_K_M. Benchmarking harness. No tools. | |
| Per-problem results: Will add soon to a site I'm building. | |
|  | |
| Run 2: | |
| 21 / 30 = 70.0% with thinking on, up to 24K tokens, temperature 1.0, 1 sample, Q8_0. Benchmarking harness. No tools. | |
| Per-problem results: Will add soon to a site I'm building. | |
| ### Selection league | |
| Scored on hard coding questions, plus some maths, agentic and reasoning tasks. No repeat questions and a large pool to avoid over-selecting for benchmarks. | |
| NO BENCHMARK QUESTIONS, all generated by Claude including some questions that are extremely hard. The league questions varied between models and the questions | |
| were not enough to find true representative results. | |
| (0 / 0.5 / 1 per answer, Q4_K_M, temperature 1.0). Vulcan finished first. Plain CherryPit 1.2 is shown as the baseline. Note: While this is at the baseline, | |
| there are many generated models that were below it. CherryPit was chosen for a reason, it's well above its class. | |
|  | |
|  | |
| | model | score per question | | |
| |---|---| | |
| | **Vulcan-1-Coder** | **0.763** | | |
| | CherryPit 1.2 (base) | 0.611 | | |
| > **Note:** the league questions varied between models, so these scores are not fully representative of a | |
| > head-to-head comparison. A like-for-like benchmark is coming. | |
| ## Usage | |
| Recommended sampling: **temperature 1.0, top-p 0.95**, thinking on. Give it room to think (16K+ tokens for | |
| hard problems): short limits cut off its answers. | |
| Works in llama.cpp, LM Studio, Ollama and anything else that runs GGUF. Same architecture and size as CherryPit 1.2. | |
| ``` | |

| ## Things to come - progress | |
| #### Paper and files released - 50% | |
| Hand writing the paper and hand-making the diagrams without AI so I'll release it as soon as I can as a pre-print. | |
| I will remove secrets from the folder and clean it up. Folder currently has thousands of files and I'd say about 25% are relevant. | |
| #### More benchmarks - ? | |
| Whenever I feel up to it, adding some now. | |
| Edit: Results from AIME 2026: Vulcan-1-Coder (Q4_K_M) benchmark harness no tools. | |
| Settings: thinking on, max 24,000 tokens, temperature 1.0, top-p 0.95, 1 sample per problem, llama.cpp (CUDA). | |

| #### Quant perplexity-solver | |
| Find the quants with the best perplexity | |
| This unfortunately requires a runtime to go with it. | |
| #### Further processing - 30% | |
| I've discovered another technique that works to post-train one of these models. I'm still perfecting it but I'm already getting good results. I think the models can be optimised further. | |
| #### Qwen 27b - 20% | |
| Started the analysis process. | |
| #### STEM - 50% | |
| Static Embedding. **Experimental native runtime** for the `.stem` model format and embedding engine. The current runtime remains intentionally narrow: | |
| **static embedding tables, token IDs, FP32 or INT8, mean pooling and optional L2**. It is not yet a general-purpose encoder/ONNX/GGUF runner. | |
| It creates a .STEM format that is faster, smaller, and more accurate. | |
