# wrangler ai run failed: model not found

## TL;DR

The model name in the run call does not match a Workers AI model: typo, wrong format, or a model not available on the account. Copy the exact model id from the docs and verify it is enabled. Model names are exact strings.

```text
wrangler ai run failed: model not found
```

## Steps

1. Copy the model id from the Workers AI docs and compare character by character.
   Expected: The typo or mismatch is found.

2. Check the model is available for your account/plan.
   Expected: Availability is confirmed.

3. Fix the call to use the exact id.
   Expected: The run succeeds.

4. Centralize model ids in config, not inline strings.
   Expected: Typos have one place to live.

5. Handle model-not-found distinctly from other AI errors in the code.
   Expected: The failure mode is clear.

## When to use

- ai run fails with model not found
- the model name was typed by hand
- after a docs update

## When not to use

- the model exists (check for a plan restriction)
- the error is on input format (different problem)
- the model was removed (check the changelog)

## Tool compatibility

- wrangler
- Cloudflare Workers AI

## Variant phrasings

- "workers ai model not found"
- "ai run model not found"
- "model id typo workers ai"

## Why it happens

Model ids are opaque exact strings, and the catalog changes: models get renamed, deprecated, or gated. A hand-typed id drifts from reality, and the API's 'not found' is the only signal. Centralizing the ids turns a typo hunt into a config update.

## Edge cases

- the catalog differs by account type; verify in your own dashboard
- deprecated models fail this way; check the deprecation list
- the exact id includes the org prefix; partial names do not resolve
