Overview

Luth-LFM2-1.2B is a 1.2 billion parameter language model developed by kurakurai in collaboration with Liquid AI. It is a French fine-tuned version of the LFM2-1.2B base model, trained on the Luth-SFT dataset. The fine-tuning process, detailed in a blog post and with scripts available on GitHub, focused on enhancing French instruction following, math, and general knowledge capabilities.

Key Capabilities

  • Improved French Performance: Achieves higher scores on French benchmarks such as IFEval (59.95), GPQA-Diamond (28.93), MMLU (48.02), and Math500 (45.80) compared to its base model, LFM2-1.2B.
  • Stable English Performance: Maintains or slightly improves English capabilities, notably in Math500 and IFEval, demonstrating effective cross-lingual transfer.
  • Instruction Following: Shows enhanced instruction-following abilities in both French and English.

Good For

  • Applications requiring strong French language understanding and generation.
  • Bilingual (French-English) tasks where maintaining English proficiency is crucial.
  • Instruction-tuned scenarios in French, including mathematical reasoning and general knowledge queries.
