Great move by OpenAI. With coding agents, if you have access to a fast and cheap model, you can afford to let it rip, making lots of mistakes, and iterate until it gets things right. With the right scaffolding (AGENTS.md, SKILLS.md, etc.), a fast and light model can do great things. And when it's done, you can still have the heavyweight model come in to clean up any messes.
Plan in Opus 4.6 and let a fast model rip anecdotally seems to work very well for me. Having Opus be extremely specific with files to edit makes it even better.
Except this thing routinely ignores my AGENTS.md instructions. Very unreliable.
