New ReCo framework cuts reasoning model costs by up to 65%

Researchers have developed a new framework called ReCo (Reward-Coordinated Compression) to improve the efficiency of large reasoning models. This method addresses the issue of "overthinking" in models that use long chain-of-thought reasoning, which increases inference costs. ReCo coordinates KV-cache compression and generation penalties based on a process reward estimator, which adapts compression levels to the importance of reasoning steps and penalizes redundant token generation. The framework also includes confidence-based early stopping, leading to significant reductions in generated tokens and latency while maintaining accuracy across various benchmarks and models. AI

IMPACT This research offers a method to significantly reduce inference costs and latency for large reasoning models, potentially accelerating their deployment in resource-constrained environments.

    Fewer Tokens, Smaller Cache: Reward-Coordinated Efficient Reasoning

    Large Reasoning Models (LRMs) excel on complex tasks through long chain-of-thought (CoT) reasoning, but their lengthy intermediate steps cause severe overthinking that inflates inference cost. KV-cache compression is a common solution, yet existing reasoning-oriented methods appl…
