And half as good. I didn't have great experiences with Anthropic models in the past, but Opus 5.5 seems to have turned a major corner. It is churning through tasks significantly more quickly and efficiently.

Suggest trying it out yourself: Ask for something difficult from GPT-6 Sol and Opus 5.5 and watch what each one does. The difference is stark.

Edit: Defining "difficult" as a complex coding or systems task (or even series of them in a single prompt).

Based on my benchmark[1] it is the same price as Opus 5.5 and just as capable.
