  "textContent": "Thanks for the constructive feedback earlier, which made me realize I needed to double-check my testing method more rigorously.\n\nTo completely isolate the model’s actual internal baseline and rule out any web-browsing interference, I followed up in **Codex** with a very strict constraint. I told it: _“Do not use any web search features. Based entirely on your internal training data, what is the latest OpenAI model you know of?”_\n\nHere is the exact response it gave me:\n\n> _“Based on my training data up to**June 2024** , the latest OpenAI model I am aware of is **GPT-4o**. It was released in May 2024 as OpenAI’s flagship multimodal model for text, vision, and audio at that time.”_\n\nHow on earth do we explain this?",
