Groq

Groq is an AI inference company that built custom LPU (Language Processing Unit) hardware to run language models at unprecedented speeds — 500+ tokens per second, roughly 10x faster than traditional GPU-based inference. With over 500K monthly visits, Groq has carved a niche as the speed leader in AI inference.

The Groq Playground provides a free chat interface where users can experience the speed difference firsthand, running models like Llama 3, Mixtral, and Gemma at near-instant response times. The real product is the Groq API, which developers use to build latency-sensitive applications where response speed is critical.

Groq's speed advantage is particularly impactful for real-time applications like voice assistants, interactive coding tools, and chatbots where users expect instant responses. The API is OpenAI-compatible, making migration straightforward for developers already using OpenAI's API format.

While Groq only runs open-source models (not proprietary ones like GPT-4 or Claude), its speed-to-cost ratio makes it compelling for production workloads where open-source model quality is sufficient.
