The Takeaway
-
Max scores one point better than regular Codex. That's something. But it's still worse than Gemini 3 Pro, Claude Opus 4.5, and DeepSeek v3.2. It's only on par with Claude Sonnet 4.5.
-
-
-
- The reality check: Even with this release, OpenAI is still far behind. This shows exactly why they declared "code red." The gap is real. They're not closing it fast enough.
-
-
-
What's coming: The rumors say OpenAI's upcoming model (codenamed "Garlic") arrives next week. The pressure is on. The anticipation is building. I'll benchmark it the moment it drops.

gpt‑5.1‑codex‑max was just added to API after having been introduced in Codex only 2 weeks ago. I just benchmarked it and it scored better than gpt‑5.1‑codex.
Still worse than Gemini 3 Pro and Claude Opus 4.5 and DeepSeek v3.2 but on par with Claude Sonnet 4.5.
This shows even with this release, how far behind OpenAI is and why they 'declared code red'. The rumors of the upcoming model by OpenAI codenamed Garlic next week is very anticipated now.
