But unless you're using the API, it's not just a model.

I asked Gemini Flash 3.5 through the Gemini app something that followed a similar pattern. I asked about something, it replied with outdated info, I said that's outdated, it did a web search and apologized for being wrong, then proceeded to give me good info.

That wasn't just a bare model, that was a model wrapped in a harness, driving the model and allowing for web searches for example.

GPT in Codex is even more aggressive, I often see it proactively do web searches to ensure it's not feeding me wrong info.
