Liquid AI's LFM2-2.6B-Exp Achieves 42% in GPQA, Outperforming Larger Models

This announcement highlights the impressive capabilities of Liquid AI's LFM2-2.6B-Exp model, particularly its performance on the GPQA benchmark. The fact that a 2.6B parameter model can achieve such a high score, and even outperform models significantly larger in size (like DeepSeek R1-0528), is noteworthy. This suggests that the model architecture and training methodology, specifically the use of pure reinforcement learning, are highly effective. The consistent improvements across instruction following, knowledge, and math benchmarks further solidify its potential. This development could signal a shift towards more efficient and compact models that can rival the performance of their larger counterparts, potentially reducing computational costs and accessibility barriers.

• •LFM2-2.6B-Exp achieves strong performance with a relatively small model size.
• •Reinforcement learning proves effective for improving instruction following, knowledge, and math skills.
• •The model outperforms significantly larger models in certain benchmarks.
