i wonder what's going on behind the scenes at openai after pausing frontier RL over safety concerns and shelving 6.1 Astra right before DevDay, openai seems to have shifted toward smaller, cheaper models like 6.1 sol with 6.1 terra expected next week. meanwhile anthropic is moving fast with nearly its entire 5.5 family out and fable 5.5 coming soon maybe they're doing something bigger with how it's allocating compute internally
