# gemma3-1b-functioncall-exp-mlx-4bit

Gemma 3 1B (instruction-tuned) after one general function-calling fine-tuning stage, following the FunctionGemma recipe,
quantized to 4-bit for MLX. It is the base of the four round-2 Forge specialists:

- [`forge-community/gemma3-1b-smarthome-r2-it1`](https://huggingface.co/forge-community/gemma3-1b-smarthome-r2-it1) (smart-home)
- [`forge-community/gemma3-1b-music-r2-it2`](https://huggingface.co/forge-community/gemma3-1b-music-r2-it2) (youtube-music)
- [`forge-community/gemma3-1b-gworkspace-r2-it2`](https://huggingface.co/forge-community/gemma3-1b-gworkspace-r2-it2) (google-workspace)
- [`forge-community/gemma3-1b-moviestore-r2-it3`](https://huggingface.co/forge-community/gemma3-1b-moviestore-r2-it3) (movie-store)

The full-precision weights are in [`forge-community/gemma3-1b-functioncall-exp`](https://huggingface.co/forge-community/gemma3-1b-functioncall-exp).

## Why this base

Chosen by a pre-registered rule (best smart-home dev probe, ties by suite) on the same data and gate: this base scored
probe 32/37 and suite 57/68 against plain Gemma 3 1B's 31/37 and 54/68. The margin is within noise and is reported as such.

## Training data

The function-calling stage used [`Salesforce/xlam-function-calling-60k`](https://huggingface.co/datasets/Salesforce/xlam-function-calling-60k)
(revision `26d14eb`, SHA-256 checked against the official file) and [`Team-ACE/ToolACE`](https://huggingface.co/datasets/Team-ACE/ToolACE).
Their licences and terms apply in addition to the Gemma terms.
