Groq
- +Marketed for very fast inference at low, linear per-token pricing
- +OpenAI-compatible API makes migration nearly drop-in
- +Free tier plus on-demand, batch, and on-prem (GroqRack/LPX) options
- -Serves open models only; no proprietary frontier models of its own
- -It is an inference layer, not an end-to-end agent: orchestration is on you
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
Which should you choose?
Groq is fast, low-cost llm inference on custom lpu silicon via groqcloud, best for developers, enterprise.
