Groq builds custom LPU (Language Processing Unit) chips that deliver the fastest LLM inference available. Llama and Mistral models run at 500+ tokens/second — 10-20x faster than GPU-based providers.
Reviewer scorecard
“For apps that need full server control — WebSocket servers, background workers, AI inference — Fly.io gives you the flexibility that serverless platforms don't.”
“The speed is mind-blowing. 500+ tokens/sec makes LLM responses feel instant. For latency-sensitive applications — autocomplete, real-time chat — nothing else comes close.”
“The DX has improved massively but it's still more complex than Vercel. You need to understand Docker and infrastructure. Not for beginners.”
“Speed is real but model selection is limited to open-source. No GPT or Claude. For apps that need the best model, you still need OpenAI/Anthropic. For speed-first use cases, Groq wins.”
“Fly.io is the answer for workloads that don't fit the serverless model. As AI inference goes local-first, having servers in 30+ regions matters.”
“Custom silicon for LLMs is the right long-term bet. GPUs are general-purpose. Groq is purpose-built. As open-source models match GPT quality, Groq becomes the default inference layer.”
