Groq
Chat with open models like Llama at speeds that feel almost instant.
What is Groq?
Groq isn't a chatbot company, it built custom chips called LPUs that make AI inference absurdly fast, and its free chat interface is the easiest way to feel the difference. Type a prompt to Llama or another open model and the answer appears almost as fast as you can read it, no waiting for tokens to trickle in. For developers, that same speed is available through the GroqCloud API.
Groq's hardware bet is that inference speed, not just model quality, is the next competitive battleground in AI. Its Language Processing Units skip a lot of the overhead that GPUs carry, so open-weight models like Llama and Mixtral run several times faster than on standard cloud GPU setups. The public chat app is really a demo of the hardware, but it's a genuinely useful free chatbot in its own right.
Key features
- Near-instant token generation on open-weight models
- Free browser-based chat with no signup wall for basic use
- Access to Llama, Mixtral, and other open models
- Developer API (GroqCloud) with the same LPU speed
- Model switcher to compare outputs side by side
- Generous free-tier rate limits for testing
Pros
- Speed is not marketing spin, it is noticeably faster than GPT or Claude chat
- Free tier is enough to actually get work done, not just a demo
- API pricing undercuts most GPU-based inference providers
Cons
- No access to closed frontier models like GPT or Claude
- Model selection depends on what Groq has bothered to host
- Speed advantage matters less for tasks that are thinking-bound, not typing-bound
