foxmind

foxmind is the on-device decision model of foxpilot, a browser agent for Firefox. It is an ONNX export of the agent graph of GLiNER2 multi-v1, with a batch axis.

Base model: fastino/gliner2-multi-v1 (Apache-2.0), by Fastino.

It is the same single-graph export as onnx-community/gliner2-multi-v1-agent-ONNX, with one change: every input and output has a batch axis.

Name	Shape
input_ids, attention_mask	[batch, seq]
word_positions	[batch, words]
schema_positions	[batch, schema]
cls_logits	[batch, schema - 1]
count_logits	[batch, 20]
span_logits	[batch, schema - 1, words, 8]

At batch 1 it behaves like the original export. Pad shorter rows with 0 and set their mask to 0.

Accuracy

export/verify_onnx.py in the foxpilot repository checks this export. In fp32, 14 reference calls match the Python library, and each padded batch row matches its single call within 8.0e-6 on label and span scores.

Speed

Firefox 157, WebGPU, fp32: one call with 4 prompts takes 517 ms, against 1,242 ms for 4 single calls (2.4x).
