OpenCode doesn't handle thinking tokens particularly well, so the LLMs are dumber (it doesn't pass the encrypted reasoning tokens back during multi-turn). Aider is very different in terms of UX.

Also, Octo has a couple of optional custom-trained ML models to autofix minor diff edit failures and JSON encoding errors. You'll notice on the Aider benchmarks that some LLMs end up failing due to edit format errors: Octo should have much fewer of those thanks to the autofix models.
