- Claude Opus for general discussion, design, reviews, etc.
- Codex GPT-5.4 High for task breakdown and implementation.
I often feed their responses to each other (manual copy/paste) to validate/improve the design and/or implementation. The outcome has been better than using one alone.
This workflow keeps Claude's usage in check (it doesn't eat as much tokens), and leverages Codex generous usage limits. Although sometimes I run into Codex's weekly limit and I need to purchase additional credits: 1000 credits for $40, which last for another 4-5 days (which usually overlap with my weekly refresh, so not all the credits are used up).
Do you mean Claude Code? If so, that's what I use(d) primarily for development, and Claude Desktop for general chats. My issue with Opus was that, every time I start a new task in Plan mode, it'd use 50k - 100k tokens and that'd by about 20% of the session limit. A bit of back and forth and its done for most of the work day. Just not feasible at all. The tasks I wanted it to perform were fairly small and contained, "Look at these three files @@@ and add xxx to @file. DON'T read any other files. If you need more context, ask me.". That worked sometimes but not always, still burned a lot of tokens.
I use both at the same time:

Have you tried Claude console client?

Yes I meant Claude Code client. Indeed Opus is a token eater, I usually use Sonnet because or that.
