ChatGPT is running a special model but it's also available through the API: https://platform.openai.com/docs/models/chatgpt-4o-latest

The system prompt may still make a difference though.

I could rant for quite a while about how OpenAI and Anthropic manage their apps vs their APIs. It's really quite strange that they both landed on the solution of non-public APIs that perform differently than their public APIs.

o3 Chat is also similarly wrong, saying {4}.
