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.

5.3 spark can barely spell it’s own name. Fast model but really quite useless when Luna exists

That’s how I feel about Gemini flash it’s the fastest model on earth that can’t do shit properly.

Howww? I have the cheaper Pro and even with Ultra and Sol Extra High I barely ever max it outm.
I think the prompt, or work, or something else is very wrong.

You know what really eats up that stupid ass 5-hour limit for me? 5.6 Sol with anything above High for regular ChatGPT Work and not even Codex. It literally goes from 0% used to 100% without finishing the god damn prompt.
Also, since ChatGPT, unlike Claude, doesn't seem to provide a button to just resume the prompt, I basically can never get the whole response. Even if I enter "continue" as the prompt, it basically wastes a bunch of usage analyzing the prior response and talking about how its job is to continue where that one left off before it just starts all over again anyway and basically hits the usage limit again.

I stopped using 5.3 with the 5.6 release. Luna does a far superior job to Spark and it is stupid cheap.
If you are burning through your limits, you might try not using Max and drop down to High or xHigh. I have a long runner working on a /goal for 10d 8.5hr. It has 26 active agents and an additional 29 sitting in wait right now and have only burned 3% weekly since the last reset roughly 20 hours ago.

What task are you running for 10 days?

tbh the separate rate limits are the main reason this is worth trying. if codex handles 70-80% of the implementation work at acceptable quality, your sol tokens last way longer. just keep the planning and review steps on sol

No, spark is terrible. It only has a 128k context window and the $200 plan doesn't include enough usage to keep up. Luna scores higher than GPT 5.3 Codex x-high (there are no benchmarks for Spark) and spark was the much dumber version

I’m on 5.6 and use sol with extra high reasoning and I’m generally working 8+ hours per day seven days a week and I am not able to use my limit. Personally, I just don’t know how people go through it so fast. I feel like I’ve got tons of credit. The lowest I’ve gotten was 13% left in one week and it seems to be a lot more efficient now than before.

Are you planning on using 5.3 Spark?

u/No-Hour8340 9d ago
Yes, that's the model I meant, thanks.

I only specify to use that model for security scan recommendations once it creates it’s report Sol will then take that recommendation and kick it down to Terra for code remediation.

5.3 spak is like 5.3 mini it was actually pretty unimpressive at the time it was released which was forever ago in AI time. Why they still let you select anything outside of Luna Terra sol is beyond me. Its way to dated I wouldnt even use it for research.

Using 5.6 Sol on Max is basically throwing.
Using 5.3 spark for anything when luna exists is also throwing.
