It's interesting that the benchmark they are choosing to emphasize (in the one chart they show and even in the "fast" name of the model) is token output speed.

I would have thought it uncontroversial view among software engineers that token quality is much important than token output speed.

Fast can buy you a little quality by getting more inference on the same task.

I use Opus 4.1 exclusively in Claude Code but then I also use zen-mcp server to get both gpt5 and gemini-2.5-pro to review the code and then Opus 4.1 responds. I will usually have eyeballed the code somewhere in the middle here but I'm not fully reviewing until this whole dance is done.

I mean, I obviously agree with you in that I've chosen the slowest models available at every turn here, but my point is I would be very excited if they also got faster because I am using a lot of extra inference to buy more quality before I'm touching the code myself.

I'd love to hear how you have this set up.

This is a nice setup. I wonder how much it helps in practice? I suspect most of the problems opus has for me are more context related, and I’m not sure more models would help. Speculation on my part.
