FAQ

Short answers for the early-access API.

The API is in early access, a private preview.

What is a Compiled Agent Model?

A Compiled Agent Model is a model for agent work. It is much cheaper and faster than frontier models on work you already run. On our tests, repeat runs are often 10-100x cheaper, and the home page shows early repeat runs as 5–10× faster.

How do I get an API key?

Open the dashboard at https://inferenceindex-app.web.app. Sign in with the same Google account as the InferenceIndex site, enter your invite code, and get an API key there. Each invite code works once.

What base URL and model do I send?

The base URL is https://api.inferenceindex.com/v1. The model is workflow/auto. The call is OpenAI-compatible chat completions. Python uses base_url. TypeScript uses baseURL.

Can I use it from Cursor, Claude Code, or Codex?

Cursor takes the OpenAI-compatible base URL in Settings, then Models. Codex takes it in ~/.codex/config.toml. Claude Code's own base URL speaks the Anthropic Messages API, so use the quickstart call from the code you are writing. The coding-agents page is https://inferenceindex.com/docs/coding-agents.

What do calls cost?

Calls spend credits. The dashboard shows the balance. Published tests are the figures to quote: often 10-100x cheaper on our tests, with one invoice run roughly 450x versus Opus 5.5.

What is a fallback model?

A fallback model is a model you choose in the dashboard, alongside workflow/auto.

Where are logs?

Logs are in the dashboard. They list your API calls: when the call ran, the model name, and whether it completed.

Is the API generally available?

The API is in early access. It is a private preview. Get a key at https://inferenceindex-app.web.app. The home page waitlist is https://inferenceindex.com/#waitlist.

What about security reviews?

SOC 2 is in progress.
