# gliner2.5-multi-v1-onnx

ONNX export of [fastino/gliner2.5-multi-v1](https://huggingface.co/fastino/gliner2.5-multi-v1) (GLiNER 2.5
`BoundaryExtractor`) for onnxruntime-web / WebGPU. **Revision 5:** revision 4
plus `candidate_states` on the main graph and a tiny `records.onnx` assignment
head.

One encoder pass. JointIE beam, classification `implies`/`excludes`, and record
assignment stay in JavaScript.

Host packing and decode: [Pastel-Org/gliner2.5-onnx-webgpu](https://github.com/Pastel-Org/gliner2.5-onnx-webgpu)
(live: [gliner25-onnx-webgpu.pages.dev](https://gliner25-onnx-webgpu.pages.dev)).

## Files

| File | Role | Size |
|------|------|------|
| `onnx/model.onnx` | Encoder + entity pair path + classifier + `text_states` + `candidate_states` | 1121.5 MB |
| `onnx/heads.onnx` | `SparseRelationScorer` only (no encoder) | 23.7 MB |
| `onnx/records.onnx` | RecordHead assignment (inst/field/cand projections + null column) | 1.19 MB |

## model.onnx outputs (new in v5)

`candidate_states` `[B, Q, C, H]` — C=192. Needed by `records.onnx`. Unused heads:
pass length-1 indices with mask 0.

## records.onnx

Inputs: `inst_states [B,N,H]`, `inst_mask [B,N]`, `field_query_states [B,F,H]`,
`field_cand_states [B,F,C,H]`, `field_cand_mask [B,F,C]`.
Outputs: `assign_logits [B,N,F,1+C]` (col 0 is ABSENT), `object_logits`,
`latent_logits`. Natural mode seeds instances from the first `::str` field's
candidates above threshold.

## Still not in ONNX

`score_explicit_spans` (pair-reranker broadcast does not export). The demo
attaches attributes by looking up the same `(start,end)` on attribute `[E]`
queries. Full Kleene classification AST is not ported; README `implies` /
`excludes` is a JS beam.
