	# small-code-coder-1.5b-tools

	A LoRA fine-tune of Qwen2.5-Coder-1.5B-Instruct that teaches the model to emit
	native `<tool_call>` function calls, so a ≤2B coder model can drive an agentic
	coding loop.

	Built for [smolcode](https://gitea.poyner.ai/sean/smolcode) — an SLM-optimized
	agentic coding assistant — for the Hugging Face Build Small hackathon.

	## Why
	Out of the box, small Qwen-Coder models describe tool calls as plain-text JSON
	instead of emitting the native `<tool_call>` format that runtimes (Ollama,
	llama.cpp) parse — which breaks agentic tool-use loops. This fine-tune closes
	that gap on a tiny (≤2B, Tiny-Titan-class) model.

	## Training
	- Base: Qwen/Qwen2.5-Coder-1.5B-Instruct
	- Method: bf16 LoRA (r=16, α=32) on attention + MLP projections, **assistant-only
	loss** (loss on tool calls + final answers only).
	- Data: NousResearch/hermes-function-calling-v1 (breadth) + synthetic smolcode
	tool-use trajectories (sharpness on the actual 5 tools), all rendered through the
	same `apply_chat_template(tools=...)` used at inference — so the training target
	is byte-identical to the served prompt.
	- Schedule: 3 epochs, full 2048 sequence length.
	- Hardware: trained on Modal (x86/CUDA); served on NVIDIA DGX Spark (GB10).

	## Use
	Standard Qwen2.5 chat template with `tools=`. The model responds with
	`<tool_call>{"name": ..., "arguments": ...}</tool_call>` when a tool is warranted.

	## Status — v2
	v2 fixes the v1 train/inference template mismatch (v1 hit 0.92 teacher-forced token
	accuracy but decoded degenerately because it was trained on a hand-rendered Hermes
	ChatML format, not Qwen's `apply_chat_template` output). v2 trains and serves through
	one shared template and is gated on a free-generation tool-call parse-rate eval
	(≥90% on held-out smolcode prompts) before release — see `eval_toolcall.py` in the
	smolcode repo.
