Everyone is interested in using less tokens to accomplish the same task.
Marginally better answers?
Claude Code and co. can now analyze an enterprise codebase to debug issues in a system with multiple services involved.
I don't see how that would have been possible at all in the past.
Personally, I would have used all those tokens to generate synthetic data for IDA (iterated distillation and amplification) so that the more efficient 1000 token/answer chat model can answer more questions, but apparently that doesn't justify an insane datacenter buildout.
