What Is Cerebras? The Chip Company That’s Also a Free AI API Cerebras Systems is best known for building the Wafer-Scale Engine (WSE) — a chip the size of a dinner plate with over 4 trillion transistors, purpose-built for AI. What most developers don’t realize is that Cerebras also offers a free cloud inference API that consistently outpaces Groq on smaller models and rivals it on 70B-class models. If you’ve only heard of Groq as the “fast free AI API,” it’s time to put Cerebras on your radar. No credit card required, OpenAI-compatible endpoint, and benchmarks that speak for themselves. In this guide, you’ll learn how to get your free Cerebras API key, make your first call with Python or JavaScript, and connect it to OpenClaw for a fully free, ultra-fast AI agent. Why Cerebras Is So Fast: The Chip Story in 60 Seconds To understand why Cerebras is fast, you need to understand why GPUs are slow at inference.…
