What is Replicate?
Replicate is a hosted service for running machine learning models through an API, with client examples for Node, Python and plain HTTP. Its homepage summarizes the product as running and fine-tuning models and deploying custom models with one line of code.
The catalog holds thousands of open-source models contributed by the community, plus a range of proprietary models, covering image, speech, music and video generation as well as large language models. Developers who need their own model can package it with Cog, Replicate's open-source packaging tool, and deploy it as a private model.
You pay for what you use. Some public models bill by hardware and time, with a per-second price that depends on the hardware, while others bill by input and output, for example per output image or per million tokens. Most private models run on dedicated hardware, so you pay for all the time the instances are online, including setup and idle time. Fast booting fine-tunes are the exception and bill only for active processing time. Each model page shows a cost estimate.
