alt Hacker NewsMy workflow was usually to use Gemini 2.5 Pro (now 3.0) for high-level architecture and design. Then I would take the finished "spec" and have Sonnet 4.5 perform the actual implementation.

I use plan mode in claude code, then use gpt-5 in codex to review the plan and identify gaps and feed it back to claude. Results are amazing.
This is how I do it. Though, I've been using Composer as my main driver more an more.
* Composer - Line-by-Line changes * Sonnet 4.5 - Task planning and small-to-medium feature architecture. Pass it off to Composer for code * Gemini Pro - Large and XL architecture work. Pass it off to Sonnet to breakdown into tasks.
I like this plan, too - gemini's recent series have long seemed to have the best large context awareness vs competing frontier models - anecdotally, although much slower, I think gpt-5's architecture plans are slightly better.
Same here. But with GPT 5.1 instead of Gemini.
I've done this and it seems to work well. I ask Gemini to generate a prompt for Claude Code to accomplish X
Same here. Gemini really excels at all the "softer" parts of the development process (which, TBH, feels like most of the work). And Claude kicks ass at the actual code authoring.
It's a really nice workflow.
