q1-3B-PRIME, a small reasoning model trained with reinforcement learning.

Trained using SmallThinker-3B-Preview as a base model (Qwen2.5-3B-Instruct full finetuned on QwQ reasoning traces) for a roughly ~22.5% improvement on the test set in 120 training steps. (Note: lots of performance left on the table since PRIME saturates after 300+ steps.)
