Consensus Brief

The article discusses the fine-tuning of the LFM2.5-350M model using Group Relative Policy Optimization (GRPO) to enhance its performance on structured output tasks. The model's performance improved from 22.6% to 29.7% on the IFStruct benchmark after fine-tuning. This process is designed to make smaller models more effective in generating valid, parseable outputs.
