# LLM API: The model `x` does not exist or you do not have access to it (model_not_found / not_found_error)

**Code:** `model_not_found` · **Category:** API · **Seen on:** REST API

The model name is wrong, deprecated/retired, or not available to your account/region.

## Meaning

Model IDs change with new releases and old ones are retired. Typos, using a display name instead of the API ID, or models not enabled for your org/cloud region cause it.

## Common causes

- Typo or display name instead of API model ID
- Model retired/deprecated
- Model not enabled for your account, org or cloud region
- Using a model from another provider’s naming

## Quick fix

1. List available models via the API
2. Update to a current model ID
3. Check access/region availability (Bedrock/Vertex model access)

## Detailed fix by platform

### Shell

1. `curl -s https://api.anthropic.com/v1/models -H "x-api-key: $ANTHROPIC_API_KEY" -H "anthropic-version: 2023-06-01" | jq '.data[].id'`

## How to diagnose

1. **ID** — Exact string
2. **Availability** — Listed for your key/region?
