Replicate: Hosting Open AI Models Without Owning GPUs
Replicate hosts open-source AI models via Cog containers; choose it for fast access to open models without infra ownership.
26 min · Reviewed 2026
The premise
Replicate hosts thousands of open-source models with a uniform HTTP and SDK interface. It's the fastest way to evaluate or productionize Stable Diffusion, Whisper, and friends without building your own serving stack.
What AI does well here
Run open-source models behind a uniform API in minutes
Push your own models with the Cog containerization tool
Pay per-second of compute with no idle costs
What AI cannot do
Match the per-token economics of frontier API providers for popular LLMs
Avoid cold-start latency on rarely-used models
Substitute for owning your own GPUs at scale
