OpenAI Has a Model Beyond Astra + GPT-6 Sol & Grok 4.7 RELEASES!?
OpenAI says it has an internal model significantly more capable than GPT-6 Astra. Could it be the model people are calling Bel—and could that become GPT-7? Let's go through the original reports, the math breakthroughs, the Doug and Bel leaks, and what they actually tell us about the next generation. GPT-7 is my prediction, not a model name OpenAI has announced. We also get into Grok 4.7 expectations and my prediction that it lands September 16. What would you want to try first with a model beyond Astra? Let me know in the comments.
