What happened
web-edit 0.1a1 is a web app for editing files in a folder, released by Simon Willison. The post states its performance optimizations were written by Claude Opus 5.5 after Willison fed it a Python 3.15 profiling report generated by GPT-6 Astra. No benchmarks, repo link, install steps, or measured before/after numbers appear in the text.
Why it matters
The only transferable detail is the workflow: a profiling report was produced by one model and handed to a different model to implement the optimizations. If you want to copy that, generate an actual profiler output for your own app first, then hand that report to a coding model, instead of asking a single model to 'make it faster' blind. Everything else here — the tool itself, whether the optimizations worked, how fast it is — is unsupported by the text, so don't plan around it.
Discussion angle
Does splitting the job across two models — one to profile, one to patch — actually beat a single model doing both? Ask anyone who has tried it whether they measured the result or just trusted the diff.
