Six free AI API keys on one page: what you get, the real limit, how to start, and the catch

The companion to the reel. One map of every free AI API key that needs no credit card in October 2026, then one card per provider. INSIDE: (1) THE MAP — Google Gemini (free tokens on Gemini 3.8 Flash), Groq (1,000 requests a day on gpt-oss-120b), NVIDIA build (up to 40 requests a minute), OpenRouter (50 free-model requests a day), Mistral Free mode (on by default), Cloudflare Workers AI (10,000 Neurons a day). (2) PICK IN 10 SECONDS. (3) ONE CARD EACH — the official quote, where to get the key, the base URL, best use and the catch. (4) USE TWO KEYS — a 20-line Python fallback that switches keys when one hits its limit. Plus why Cerebras is no longer on the list. Quoted from each provider's official page on Oct 13, 2026. Independent guide from Hyperautomation Labs — not affiliated with Google, Groq, NVIDIA, OpenRouter, Mistral AI or Cloudflare.
