Ask HN: Claude Code with Multiple Models?
GPT-5 seems stronger at generating diverse ideas, pros/cons, and perspectives, while Sonnet 4.5 feels better at decision-making and writing code. Has anyone tried running them together in Claude Code? Did it improve results?
I'm asking claude code to collaborate with codex. You can do it by adding codex as a mcp server. They added `codex mcp-server` command for user to use codex as a mcp server recently. And it did improve the plan and code quality; I ask it to review the plan and generated code. Full command is like this: `claude mcp add codex -- codex mcp-server`
Nice. I will give it a try. thx
Sonnet 4.5 is objectively worse at writing code unless it’s like make me a color picker. IME at least as someone who is going through millions of tokens daily.
Codex high is kind of a beast, even better than Opus which Anthropic decided to limit for their max uses. https://github.com/anthropics/claude-code/issues/8449
Check out https://opencode.ai/ it’s similar to Claude code, but works with many models.
