Replicate

Replicate is a platform that lets developers run thousands of open-source AI models behind a single API. It is billed per use with no monthly subscription. You can generate images, videos, speech, and music, or run large language models. It also supports fine-tuning and deploying custom models. Many models are billed by runtime or by input/output tokens. For example, Flux image models cost $0.04 per output image. The platform is designed for developers and solopreneurs who need to integrate AI features into their applications without managing infrastructure. Typical use cases include generating marketing visuals, creating audio content, and building AI-powered chatbots.
