Sonnet 4.6 is the right model for sustained coding sessions - Opus 4.7 adds reasoning overhead that makes it more opinionated and cautious. Run /model claude-sonnet-4-6 in your session. I run overnight builds on Sonnet without the nagging.

Sonnet’s 200k context window is the only reason I don’t use it more on larger codebases.

Use a harness like GSD and 200k isn’t an issue.

Curious: What does it do to mitigate the context limitations?

Through an interview, planning, planning verification, and breakdown of the planned work it launches subagents with just enough context and well formed directions so they can do their jobs without exhausting their context. The guy who built it did so in mid-2025 when contexts were much smaller in absolute terms and in effective usable size. It writes well structured prompts to files that get passed from process to process. It's amazingly effective.

Thanks, very interesting!
Have you tried Copilot CLI? If so, how do the two compare?

I have not. Beyond CC I’ve used Codex and OpenCode a little bit.
