new openai model has been spotted in arena looks like this one is 6.1 luna as outputs are not looking as good as terra but i don't understand the need to release these small models when your competitor have the best models in the world and the way 6.1 family is going, i don't feel like 6.1 astra would be any better openai needs to lock in and release whole new family that's best at everything, like claude 5.5 family i still have high expectations as tibo said it's gonna be big week
