# M302: Model not available

> Manifest error M302 fires when an explicit model ID is not available for the authenticated agent. Fix: use GET /v1/models or make the provider available for this agent.

## What you saw

```text theme={"theme":{"light":"github-light","dark":"github-dark"}}
[🦚 Manifest M302] Model "openai/gpt-4o" is not available for this agent. Use GET /v1/models to list available model IDs, or make the provider available for this agent here: https://app.manifest.build/...
See https://manifest.build/docs/errors/M302
```

The model name varies based on the `model` value your client sent.

## Why it happened

You sent a concrete model ID instead of `auto` to an OpenAI-format endpoint, but that model is not available to this agent.

This can happen when:

1. The model ID is misspelled or retired.
2. The provider is not connected yet, or it is connected but not enabled for this agent.
3. You used a provider-native name when Manifest expects the exact ID returned by `GET /v1/models`.
4. Manifest refuses the request instead of falling back to automatic routing.

## How to fix it

1. Call `GET /v1/models` with the same Manifest agent key.
2. Use `auto` to let Manifest route, or copy one of the listed model IDs exactly.
3. If the model should be available, open the dashboard link in the error and enable or connect that provider for this agent.
4. Retry the request.
