UnverifiedPI选择flow matching而非diffusion的一个重要工程原因是推理效率，flow matching所需的积分步数远少于扩散模型的去噪步数70% similarUnverifiedflow matching推理通常10-20步积分即可，而扩散模型需要50-1000步去噪66% similarUnverifiedText-to-image models such as Stable Diffusion 3 and Flux adopt the Flow Matching framework.65% similarVerifiedFlow Matching continuously maps a noise distribution to a data distribution by learning a deterministic velocity field, and both Stable Diffusion 3 and Flux adopt this framework.63% similarUnverifiedThe mathematical essence of diffusion models is based on stochastic differential equations and score matching theory, underpinning image generation systems such as Stable Diffusion and DALL-E.62% similar
