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.
- Prefer 2K Recommended (e.g.,
2048x1360/2048x2048) — significantly higher success rate, same $0.03/image - 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
- For guaranteed 4K — switch to the official-proxy
gpt-image-2+image2Enterprisegroup. The official-proxy 4K is pricier (~$0.3+/image), but markedly more stable — appropriate when 4K delivery is a hard requirement
