Apple researchers introduce probe guidance, a method to guide flow matching models that uses frozen internal states from existing diffusion models to construct guidance signals. Applied to a 1.7B diffusion language model, probe guidance achieves state-of-the-art performance on unconditional generation and improves multiple choice question answering benchmarks while eliminating the need for additional forward passes at inference time.

## Evidence

Verbatim from https://machinelearning.apple.com/research/guide-language-flow:

> Our approach, which we call probe guidance, uses the frozen internal states of an existing diffusion model to construct a guidance signal. This works using a similar principle as autoguidance, but eliminates the need for an additional forward pass at inference time and provides a reliable path to ensure that the weak and strong model share similar dynamics.
