New framework enhances continuous flow language models with reinforcement learning

Researchers have developed a new post-training framework called \method{} designed to enhance the reasoning capabilities of continuous flow language models. This framework utilizes a critic to estimate the value of intermediate token embeddings, enabling pathwise gradients with lower variance than traditional REINFORCE methods. By predicting values from every token representation, the critic aids policy optimization. Experiments across four reasoning tasks demonstrate that \method{} effectively improves continuous flow language models through reinforcement learning, outperforming existing baseline methods. AI

IMPACT This research could lead to more capable continuous flow language models, potentially improving performance on complex reasoning tasks.
