What is Groq?

Groq is a hosted inference service that runs open-weight language models on its own LPU chips rather than GPUs. Developers call it through an OpenAI-compatible API, so most existing code works after swapping the base URL and key. Its selling point is latency: token generation is fast enough that chat responses and voice agents feel immediate, which matters for real-time applications. The catalogue covers Llama, Mistral, Qwen and other popular open models, and the free tier is generous enough to benchmark speed before committing to paid usage.

Key features

  • OpenAI-compatible chat completions endpoint at a different base URL
  • Hosted Llama, Mistral, Qwen and other open-weight models
  • Speech-to-text and text-to-speech endpoints alongside chat
  • Very low time to first token for streaming responses
  • Batch requests and structured output through the same API
  • No model hosting or GPU capacity planning on your side

Pros & cons

Strengths

  • Latency is the standout feature for interactive and voice apps
  • Drop-in OpenAI SDK compatibility keeps migration cheap
  • Free tier lets you test real throughput before paying

Watch out for

  • Model choice is narrower than large aggregators offer
  • You cannot bring your own fine-tuned weights
  • Rate limits on lower tiers constrain heavy production load

FAQ

Why is Groq faster than GPU providers?

Groq runs models on its own LPU chips designed for sequential token generation rather than general GPU work. That architecture produces very low latency, which shows up most in streaming chat and voice applications.

Can I reuse my OpenAI code?

Yes, in most cases. The chat completions endpoint follows the OpenAI format, so you usually change the base URL, the API key and the model name without touching the rest of your code.

Can I run my own fine-tuned model?

No. Groq serves its own catalogue of open-weight models and does not accept custom weights. If you need a tuned model, a platform with custom deployment is a better fit.
