# gpt-image-2-vip 4K occasional 500 errors · OpenAI compute fluctuation · mitigation tips

> gpt-image-2-vip occasionally returns 500 errors at the 4K Detail tier due to OpenAI compute fluctuation, not request parameters. Mitigation: prefer 2K, send fewer input images. For guaranteed 4K, switch to official-proxy gpt-image-2 + image2Enterprise group (~$0.3+/image).

⚠️ **`gpt-image-2-vip` 4K tier occasional 500 errors · root cause: OpenAI compute fluctuation · mitigation tips** — A field note: lately `gpt-image-2-vip` has been occasionally hitting `status_code: 500` at the **4K Detail** tier (e.g., `3840x2160` / `2880x2880`), upstream returning `invalid_request_error`. Root cause is **OpenAI compute fluctuation** — not request parameters; the same request usually goes through at 2K.

```json theme={null}
{
  "status_code": 500,
  "error": {
    "message": "An error occurred while processing your request. You can retry your request, or contact us through our help center at help.openai.com if the error persists. Please include the request ID xxxxxxxx in your message.",
    "type": "invalid_request_error",
    "code": null
  }
}
```

💡 **Mitigation tips (by cost-effectiveness)**:

1. **Prefer 2K Recommended** (e.g., `2048x1360` / `2048x2048`) — significantly higher success rate, same **\$0.03/image**
2. **Send fewer input images** for img2img / multi-image fusion — the Codex reverse channel struggles under heavy input load, further pushing up 4K failure rates; pre-compressing each input image **under 1.5MB** also helps
3. **For guaranteed 4K** — switch to the official-proxy [`gpt-image-2`](/en/api-capabilities/gpt-image-2/overview) + **`image2Enterprise` group**. The official-proxy 4K is pricier (**\~\$0.3+/image**), but markedly more stable — appropriate when 4K delivery is a hard requirement

🎯 **Our ops principle**: **If upstream doesn't break, neither do we** — stable upstream means stable relay; when upstream wobbles, we keep investing ops effort and post status updates on Live as soon as we have signal.
