As of my last update in April 2024, OpenAI's latest flagship model is **GPT-4 Turbo**. However, OpenAI frequently releases updates and new models, so there may be more recent developments.

For the most current information about OpenAI's latest models, I'd recommend checking:
- OpenAI's official website (openai.com)
- Their blog or announcements
- Their API documentation

Is there something specific about GPT-4 or OpenAI's models you'd like to know about?
