About
LLM7.io is a free API that lets you send prompts to large language models and get answers back, with no account or API key at all. You get 500,000 tokens every 24 hours completely anonymously, or 1 million a day with a free token. It speaks the same language as OpenAI's API, so any code or agent written for OpenAI works with it by just changing the web address it calls. It routes requests across several fast models, which makes it perfect for prototyping an agent idea before you commit to a paid provider.
