OpenRouter
- +One OpenAI-compatible API and key for 400+ models across 70+ providers, with trivial model switching
- +Provider routing and automatic fallback pool uptime across providers for higher availability
- +States it does not mark up inference (provider pass-through pricing); free models and BYOK available
- -Adds a fee on credit purchases (around 5.5% pay-as-you-go) on top of provider rates
- -It is a routing layer, not an agent: it provides model access, not autonomous task execution
Replicate
- +Huge catalog of open-source models runnable with a single API call, no GPU provisioning
- +Transparent per-second (or per-output) usage billing that scales to zero when idle
- +Cog lets you package and deploy your own models on the same managed infrastructure
- -It is inference infrastructure and tooling, not a turnkey agent; you build the application around it
- -Cold boots can take tens of seconds to minutes for rarely-used models and are billed at the running rate, so latency and cost can be unpredictable without warm deployments
Which should you choose?
OpenRouter is one openai-compatible api for 400+ llms across 70+ providers, with routing and fallbacks, best for developers, smb, mid-market, enterprise.
