Gemma-4 12B Coder — SFT v1 (weights, deprecated)

⚠️ Deprecated — do not use for new work. first SFT iteration superseded by v5. Replaced by [`tpls/gemma-4-12B-coder-fable5-composer2.5-v1-sft-v5`](https://huggingface.co/tpls/gemma-4-12B-coder-fable5-composer2.5-v1-sft-v5).

gemma-4 12B coder weights (safetensors) — for fine-tuning, merging, or quantizing.

Ready-to-serve GGUF quants: `tpls/gemma-4-12B-coder-fable5-composer2.5-v1-sft-GGUF`.

At a glance

Use it — GGUF quantizations

Ready-to-serve GGUF quants live at `tpls/gemma-4-12B-coder-fable5-composer2.5-v1-sft-GGUF` (llama.cpp / Ollama one-liners on that card). These are the safetensors weights, for fine-tuning / merging / quantizing.

Intended use & limitations

Built for code generation and agentic tool use; serve locally via llama.cpp / Ollama, or use as a base to fine-tune / merge / quantize. Outputs can be wrong or fabricated — validate tool arguments before executing, and keep a human in the loop for anything consequential.

Provenance & reproduction
