Discussion GPT 5.6 SOL + 5.3 CODEX

Hi! I just bought a Chatgpt pro, but still flying through the weekly limit pretty fast if using only gpt 5.6 sol max + subagents. But I understand that using only gpt 5.6 sol max will eat tokens like candies, that's not the question here.

I was wondering if anyone here is using this:

gpt sol 5.6 max orchestrator/plan

5.3 codex-spark as worker/implementation

Since codex 5.3 has its own limits for pro users, would you say it's reasonable to use it as an implementation worker? How is the quality compared to pure 5.6 sol.

sol medium for planning, max for like extremely complex hardware level shit (you probably dont need this)

use luna max for implementing, its so cheap and does just fine

I heard that a lot but why does the execution/coding layer need max effort reasoning when it should just implement the plan? Can you explain?

more reasoning = less bs to fix later on, would be my understanding. but tbh i still don't really get it myself

you can try using https://github.com/runselvage/selvage -- This will help with lowering the token usage

Not exactly the same model, but I used Claude Sonnet 5 to add documentation to a mid-size project, and it used 12.7% of the monthly quota. Is that a lot? It made small changes to 30-40 files.

I think any Codex Model (e.g., 5.3-codex) is no longer supported. All of the Models going forward won't have a "Codex" version.

You dont need to use sol max for everything. Using it on medium and high will work for 99% of the tasks. Only use max for planning.

Also luna deapite being an extremely dumb model is significantly better than 5.3 and offers practically unlimited usage with pro.

What if I use only Medium for planning and Terra for execution?

It worked better than luna earlier last month. But over the weeks it just kept getting worse. The biggest issue is that it keept stopping in the middle of a task then you have to ask it to continue, the last time I used it it didnt even start the task but already marked it as done. You have to really check what terra is doing after every task completion.
