Flint – A 30B LLM fine-tuned for increased output diversity

A fine-tuned Qwen3 30B model specifically engineered to address the lack of output diversity in frontier LLMs for open-ended queries, demonstrating that "divergence tuning" can significantly increase novelty without compromising performance on non-creative tasks.

Flint addresses a critical limitation of current frontier LLMs: their tendency towards repetitive or low-diversity outputs, especially for creative or open-ended tasks. By demonstrating that a 30B model can be fine-tuned for significantly higher entropy and novelty without sacrificing core capabi...
