GPT, Claude, Gemini and Grok behind one OpenAI-compatible API.
Who is LLMFly AI best for?
LLMFly AI is best for developers who want GPT, Claude, Gemini and Grok models through one key.
Apps that call several providers
GPT, Claude, Gemini and Grok models sit behind one OpenAI-compatible endpoint, so you change the base URL and model ID instead of adding a new SDK for each.
Coding agents on a budget
Setup guides cover Claude Code, Codex, Cursor and Cherry Studio, and GPT models bill at 0.3x OpenAI's list price.
Separate keys per project
Each app or environment can get its own key, so a leaked key can be revoked without taking the others offline, and the usage log shows what every request cost.
