# kimi-k2

Calls to the model kimi-k2 on Moonshot AI stopped working on May 25, 2026.

Moonshot AI retired model kimi-k2 on May 25, 2026. Calls specifying model kimi-k2 fail since that date. Any request using this identifier no longer receives responses.

## The error Moonshot AI returns once kimi-k2 is gone

HTTP 404

```json
{"error":{"message":"Not found the model kimi-k2 or Permission denied","type":"resource_not_found_error"}}
```

## What to use instead
