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.
