Replicate lets you run open-source models (Llama, Stable Diffusion, Whisper) via API without managing GPUs. Push your own models with Cog or use community models. Pay only for compute time.
Reviewer scorecard
“Run any Docker container globally with `fly launch`. The Machines API for programmatic VM creation is uniquely powerful.”
“The easiest way to run open-source models without managing infrastructure. One API call to run Llama, Whisper, or any custom model. Cold starts can be slow though.”
“Global deployment is its strength. For edge-first architectures, Fly.io solves distribution better than anyone.”
“Cold start latency is the main issue — first request can take 10-30 seconds. Fine for batch jobs, problematic for real-time. But the convenience factor is huge.”
“Apps running close to users is the future. Fly.io's Machines API enables new categories of distributed applications.”
“Replicate is making open-source AI as easy to use as closed APIs. That is the right mission at the right time.”
