GLiNER2 and GLiNER2.5 ONNX bundles
Explicit, opt-in model downloads for codesoda/gliner2-rs. Rust build and inference do not require Python. These are fp32, ONNX opset 17 conversions, not Fastino's original safetensors checkpoints.

Each 2.5 directory includes seven graphs: encoder, classifier, boundary
marginals, shared scorer, explicit scorer, records and relations. Config and
tokenizer metadata, the original model card, Apache2 license and conversion
notice are colocated. export_manifest.json records required files, sizes,
SHA-256 hashes, actual graph signatures, source identities and validation.
validation_report.json contains measured checkpoint-specific source/ONNX/native
evidence; export_manifest.unvalidated.json preserves the pre-review inventory.
The existing v2 graph files remain unchanged. The project downloaders also fetch v2 tokenizer/config metadata from the immutable original Fastino revisions above and colocate it with the downloaded graphs.
Validation and runtime
Original GLiNER2 source: d7c727458bf6929bc9ef5ee04e13c3f717a7c455.
The Rust runtime uses direct ort 2.0.0-rc.13 / native ONNX Runtime 1.28.
Development Python validation uses separately pinned ONNX Runtime 1.20.1 and
PyTorch 2.8.0; it is not a Rust runtime dependency.
Each 2.5 checkpoint passed seven source/ONNX stage gates and 32 native cases (30 closed-corpus, one mixed Unicode and one explicit duplicate-span case). Discrete results and original UTF-8 byte coordinates match exactly. Numerical bounds, maximum errors, source hashes and runtime details are in each report. These are bounded CPU/reference results, not a universal bit-identity guarantee across architectures or execution providers. The exported centered sum preserves the pinned AArch64 PyTorch fp32 order; no precision/tolerance relaxation was used.
Unsupported zero-axis native diagnostics are not a supported graph contract; Rust guards reject or bypass those calls. Empty user text is handled by the public preprocessing path. Optional attributes, JointIE and chunk/merge helper APIs are not implied by these bundles.
Download
From a current checkout of codesoda/gliner2-rs, choose this repository's full,
immutable 40-character snapshot commit, not main:
cargo run --release --example download_models -- \
--model 2.5-base --dest ./onnx --revision <snapshot-commit>
# Or, explicitly using the optional development downloader:
python3 scripts/download_models.py \
--model 2.5-base --dest ./onnx --revision <snapshot-commit>
Selectors are base, large, 2.5-small, 2.5-base, 2.5-multi and all.
all downloads all five bundles and several gigabytes. The downloaders reject
partial/unvalidated boundary manifests, unsafe paths and size/hash mismatches.
Do not infer that an older crate tag contains the 2.5 APIs: use the documented
GitHub release or a verified source commit.
