Groq Has a Free API: The Fastest LLM Inference Engine (18x Faster Than GPT-4)

What is Groq? Groq is an AI inference company that built custom hardware (LPU — Language Processing Unit) specifically for running LLMs. The result: 500+ tokens/second output speed, making it 10-18x faster than OpenAI. And they offer a generous free tier. Why Groq is a Game-Changer Free tier — generous rate limits for development 500+ tokens/sec — responses feel instant (GPT-4 does ~30 tokens/sec) OpenAI-compatible API — drop-in replacement Llama 3, Mixtral, Gemma — all major open-source models Custom LPU hardware — not GPUs, purpose-built for inference Quick Start pip install groq from groq import Groq client = Groq ( api_key = " your-api-key " ) # Free at console.groq.com response = client . chat . completions . create ( model = " llama-3.3-70b-versatile " , messages = [{ " role " : " user " , " content " : " Explain microservices vs monolith in 3 sentences " }], temperature = 0.7 ) print ( response . choices [ 0 ]. message . content ) # Response arrives in <1 second for short prompt
