🚨 GPT-6 Sol might be the model that makes GPT-6 Astra less interesting. 👀 Astra is built for the hardest problems. But early Sol leaks point to something very different: - 6x faster in one reported test - Strong coding - Heavy RL trained - Potentially much cheaper If that's real, OpenAI may not need Sol to beat Astra. It just needs to be good enough that you stop reaching for Astra. That's a much more interesting fight. 👀🔥
