Groq
Ultra-fast AI inference chip and API. Get responses 10-100x faster than GPU clouds with LPU hardware.
What is Groq?
The Fastest AI Inference on Earth
Groq is an AI infrastructure company that built a custom chip — the Language Processing Unit (LPU) — specifically designed to run large language model inference. The result is token generation speeds that can be 10 to 100 times faster than GPU-based cloud providers, enabling real-time AI experiences that feel instantaneous.
The LPU Advantage
Traditional GPUs were designed for training neural networks, not inference. Groq's LPU architecture eliminates the memory bottlenecks that limit GPU inference speed, enabling sustained output of hundreds to thousands of tokens per second even for large models like Llama 3 70B and Mixtral 8x7B.
- Llama 3, Mixtral, Gemma, and Whisper available via the API
- OpenAI-compatible REST API
- Competitive per-token pricing with a generous free tier
- GroqCloud playground for instant experimentation
Key Features
LPU hardware delivers 300-800+ tokens per second — making responses feel instantaneous even for long outputs.
OpenAI-compatible REST API with support for Llama 3, Mixtral, Gemma, and Whisper speech-to-text.
Experiment with any supported model directly in the browser with no setup or code required.
Fast, accurate speech-to-text transcription using OpenAI's Whisper model on Groq's fast hardware.
Generous free rate limits allow substantial experimentation and small production workloads at no cost.
Who Uses Groq?
Build chatbots and voice assistants where sub-second response times are essential for user experience.
Combine fast transcription with fast LLM inference to build low-latency voice AI pipelines.
Power games, coding tools, and productivity apps where waiting for AI responses would break the flow.
Iterate on prompts and test ideas quickly when fast feedback loops dramatically accelerate development.
