> A fine-tuned version of Google's Gemma 4 31B optimized for natural human conversation style and voice, with GGUF, Safetensors, FP8, and GPTQ-Int4 weights available for local deployment.

The developer has released `Gemma-4-31B-Humanlike-Chat`, bringing the training method from the previous Qwen 2.0 human-like chat fine-tune to Google's official Gemma 4 31B model.

### Features & Improvements
- **Human-Like Chatting**: Text naturally without complex prompts, using short lowercase lines and responsive dialogue style.
- **Benchmarks**: Outperforms the official base model in When2Call (66 vs 46), BFCL irrelevance (90 vs 81), and BFCL simple (96 vs 95), while maintaining identical MMLU-Pro knowledge levels (82.5).
- **Training Recipe**: Built on `google/gemma-4-31B-it` under Apache-2.0 license, using SFT and 12-step on-policy distillation to resolve the tendency of generating single-word replies in long conversations.
