2026/5/22 16:25 (UTC+8) · Model Status · OpenAI ⚠️ 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.
💡 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 + 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. 📖 Detailed guidance has been added to: gpt-image-2-vip overview · FAQ 📖 About the image2Enterprise group: /en/live/2026-04/image2-enterprise
