GPT 6 Sol and Opus 5.1 are both coming within the next 2 weeks. These are the releases that actually matter. Fable 5.1 and GPT 6 Astra are incredible models that nobody can afford to run consistently. Session limits die in minutes. Weekly limits die in days. We do not need smarter models right now. We need intelligent models that are affordable enough to actually use in our workflows. GPT 6 Sol and Opus 5.1 are supposed to be exactly that. The biggest week in AI is not about the frontier. It is about making the frontier usable.
