🚨 GPT-6 Sol will probably end up dropping on thursday then From trying it for a little bit it feels faster than 5.6 Sol, I think it's the token efficiency maybe but idk 🤷‍♂️ Im guessing this is dropping earlier than expected due to compute capacity issues, I bet this was meant to come on dev day originally (purely speculative)
