🔗 Better Models: Worse Tools

🫧 Open on Bubbles Armin theorizes that this is because more recent Anthropic models have been specifically trained (presumably via Reinforcement Learning) to better use the edit tools that are baked into Claude Code. This has the unfortunate effect that other coding harnesses, such as Pi, may find that their own custom edit tools are more likely to be used incorrectly. Claude’s edit tool uses search and replace . OpenAI’s Codex uses an apply_patch mechanism instead , and OpenAI have talked in the past about
