A unified AI API for every model
Managing API keys, SDKs, and billing across OpenAI, Anthropic, Google, and Meta is overhead that slows you down. InferAll consolidates 255+ AI models behind a single API key and endpoint.
Get your API keyThe problem with multiple AI APIs
Every AI provider has its own API format, authentication scheme, SDK, and billing portal. Building with multiple models means managing multiple API keys, handling different request/response formats, and reconciling separate invoices.
When a new model launches, you need to integrate yet another provider. When you want to compare models, you need to build abstraction layers. When you want to switch providers, you need to rewrite integration code.
One API key, every model
InferAll is a unified AI API that gives you access to OpenAI GPT-4o, Anthropic Claude Sonnet 4, Google Gemini 2.5, Meta Llama 405B, and 250+ other models through a single endpoint. Use one API key, one SDK, one bill.
The API is compatible with the OpenAI and Anthropic formats you already use. Point your existing code at api.inferall.ai and it works immediately.
Works with your tools
InferAll works with any tool that supports the OpenAI or Anthropic API format, including Claude Code, Cursor, Continue, Cline, Aider, and OpenCode.
