I'm not finding that, like not even close. I'm using it mostly to write specs and docs and having Claude and Gippity check each other's work and fix things. It's looking into other previously written MD docs, and checking against 3-4 multi-thousand file Ruby codebase(s).

5.4 takes about 50% longer, almost without fail. I'm using 'medium' effort on both.

Might be a difference in use cases. Mostly working in repos under 100k LOC, most of those are under 30k. Primarily golang, python, and terraform. Also a lot of interactive troubleshooting of Kubernetes, GHA, hardware debugging and application debugging.

I also only run in fast mode on gpt-5.4 high.
