r/ClaudeCode on Reddit: Opus plan mode = GodMode ($100 plan)

August 13, 2025 -

Been using the $100 Claude Code plan for 2 months. The default /model (Opus for 20% of usage, then Sonnet 4) was meh. Opus burned out in 15 mins on basic tasks, like driving a Ferrari to grab the mail. The new "Opus Plan Mode" is a game-changer! Worked 8 hours today, never hit the Opus limit. Opus handles the big thinking, Sonnet cranks through the work. I push back on plans until they're spot-on, and I 1 shot complex tasks all day. I skip heavy configs since Claude Code updates often as I'm here to get stuff done fast, not master it. If you haven't tried Opus Plan Mode, you're missing out!

Does it use opus on the initial process of every query then dispatch work to sonnet, or it just switch to opus when it detected the query is a planning task?

I use Serena MCP and the usage is much less! Serena creates guidelines that let’s Claude find what file it needs to edit and the context much faster and straightforward way as compared to how it usually does it! Saves alot of tokens and avoids context bloating.

New mode lets Opus handle planning while Sonnet executes the work. Basically automates what everyone was already doing manually. Super useful!

So, “Opus for planning / Sonnet for everything else” was there when it was Opus 4.1 and Sonnet 4

then they removed it with Sonnet 4.5, and added it again couple of days later

Then REMOVED IT AGAIN?!!

guys, seriously, the workflow of planning -> executing using Opus for planning and Sonnet for everything else is just perfect in terms of results,

Bring. It. Back.

🙏🫶

You can still use it but you have to put in settings.json the variable cat .claude/settings.json { "model": "opusplan" } Then when you try to select /model it will appear Trust me, i’m an engineer!🤣🤣

Havent used planning since 4.5 released. Ive not had the need. I plan through .md files.

Now that Pro has access to Opus this is a great way to make your usage last longer!

But its not worth it. Opus 4.5 is stellar better than Sonnet. It's faster and it's rare to make mistakes.

This is what the pro users should be using and executing the plan with sonnet.
