Replicate

Replicate is a cloud platform that runs thousands of open-source models, image generators, video models, speech tools, and language models, behind a single HTTP API. You call a model version with inputs, it runs on autoscaled GPUs, and you are billed per second of compute rather than per month, with nothing running while idle.

The Cog tool packages any custom model into a container Replicate can host, and built-in fine-tuning lets you train image models on your own photos or adapt open language models. Official client libraries cover Python and JavaScript, and outputs can stream. It suits developers adding generative media or niche models to products without owning GPU infrastructure; very high, steady workloads may eventually be cheaper on reserved hardware you manage yourself.
