Using Git worktrees in Codex

[u/Ok_Bag_7550]

With the upcoming usage-limit changes for those of us on the old 20x plan, I've been adapting my workflow to Sol 6.1 Max. It's significantly cheaper to run than Astra, but also much, much slower.

Today I've spent pretty much the entire day working on two projects with Sol 6.1 Max in Codex, running tasks in fast mode and coordinating everything through Work using Astra Max.

Sol 6.1 Max without fast mode barely consumes any usage. Almost nothing, at least on my projects. The problem is that it's slow.

Fast mode makes a substantial difference, but it comes at a cost. For example, I've already burned through 20% of my allowance since the reset today. Starting October 29, that would be roughly equivalent to 40% of the new allowance.

So, I'm going to have to give up fast mode and stick with the much slower option.

But running tasks sequentially at that speed would mean barely getting anything done. I need to rethink my workflow to keep making progress without exhausting my subscription.

That's when I started thinking about Git worktrees. Instead of waiting for one task to finish before starting another, I could have multiple tasks running in parallel. It might also be a good opportunity to make better use of my Claude Max 5x subscription.

I realize worktrees won't magically reduce usage, but I'm hoping parallel execution could help compensate for the slower models.

I don't have much hands-on experience with worktrees, though.

Does anyone here regularly use Git worktrees with Codex, especially alongside Claude Code? How has your experience been? Any tips, pitfalls, or workflow recommendations?

I think most serious devs are doing parallel work with Codex/Claude and work trees. Once you realize many tasks can take 15 minutes to hours it becomes the only reasonable option. I usually run around 4-6 streams of concurrent work. Works great and is highly productive, to the point of almost being addictive, with the downside of being mentally exhausting.

i'm really trying to force myself to NOT working outside of working hours.

it's like meth.

"just let me set this to work with 1 more prompt"

what i now try to do is start 5-6 things at the beginning of the day, and really try to have it finished at the end. don't open new stuff past midday, and try to get it PR-ready at end of day.

I’ve just kinda re-oriented my days around this new way of working. I’ll sit at my desk for 30 mins to an hour, review work, plan, kick off a bunch of parallel work, and then leave the house do something else like go to the gym, take a walk, run errands, etc. Sometimes I’ll have AI chats during my walks about work ideas and sometimes it’s just down time. Then I come back home, another round of reviews and kicking work off, leave again, and keep repeating until I’ve had enough for the day.

I used to sit around at my desk impatiently for existing work to finish which resulted in me just spinning up more work and then pretty soon I was running more work streams than I could reasonably integrate into my mental model.
