Groq is an AI inference provider running its proprietary Language Processing Unit (LPU) hardware that delivers the fastest available LLM inference speeds — up to 10x faster than GPU-based competitors for many models. It provides API access to Llama 3, Mixtral, Gemma, and other open-source models at sub-100ms time-to-first-token latency, enabling real-time conversational AI experiences that feel instantaneous. Developers building voice AI, real-time chat applications, and latency-sensitive AI products use Groq when response speed is the primary constraint, as its inference performance is unmatched in the current AI infrastructure landscape.
