Now it's time to test the model to draw clear conclusions not just from benchmarks, but from the real vibes of working with it. And also wait for external evaluations on the rest of the benchmarks from those who go on testing via the API. We'll keep you posted

I notice slight improvements but there they are, the blue boxes surrounding everything.

New Model Costs 20% More Than GPT 5.4 Despite Token Efficiency
By
–
Because the price of the model doubles (!!) its predecessor, buuuut this is something that's mitigated by the more efficient use of tokens But in combination, as a result, it leaves us with a model that's 20% more expensive than GPT 5.4 xhigh when it comes to evaluating
