+# Qwen3-4B File-Ops Distilled
+
+## Summary
+
+This is the first TinyGPT specialist package for a model we actually built:
+a fused Qwen3-4B-Instruct-2507 bf16 HF/MLX safetensors directory distilled for
+GorillaFileSystem multi-turn file-operation tasks.
+
+It is a **routed specialist**, not the general Pace planner.
+
+## Artifact
+
+- Package id: `qwen3-4b-file-ops-distilled`
+- Public artifact: `sarthakagrawal927/qwen3-4b-file-ops-distilled`
+- Public storage target: Hugging Face Hub model repo
+- Format: HF/MLX safetensors directory
+- Base: `Qwen/Qwen3-4B-Instruct-2507`
+- Precision: bf16
+- Training method: frontier/gold trajectory distillation rendered in the
+  student's native tool-calling chat template
+
+## Measured Result
+
+| Suite | Stock 4B | Distilled 4B |
+|---|---:|---:|
+| File-ops hard gate | 58% | 100% |
+| File-ops hardgen held-out | - | 95% |
+| Out-of-domain breadth | 59.6% | 42.3% |
+
+The file-ops domain saturated at 4B: the distilled model matched frontier on
+the hard and veryhard file-ops gates. The same training caused negative
+transfer outside that domain, so this package is only correct behind a router.
+
+## Recommended Use
+
+Use this model when the router has already identified a file-operation task
+with derivable arguments: paths, file names, directories, moves, creates,
+deletes, and navigation through a file-system backend.
+
+Do not use it as a general planner. For general multi-domain planning, use the
+planner lock in `docs/planner-lock-2026-06-19.md`: stock
+Qwen3-4B-Instruct-2507 bf16 with the plan-then-execute prompt.
+
+## Known Limits
+
+- The specialist regresses on non-filesystem BFCL multi-turn backends.
+- It was not validated as a broad Pace planner.
+- It depends on correct routing. Bad routing turns a narrow win into a broad
+  regression.
+- The artifact is multi-GB and is published on Hugging Face Hub, not committed
+  to this repository or required to remain in local cache.
