I have reached the point where the subscription scoreboard is changing how many accounts I need, not whether I still want both systems in the stack.
That is a stronger statement than “GPT-5.6 is good.” I have been cooking with 5.6 Sol Ultra hard enough to find the edges: one or two serious chats moving almost all the time, broad briefs that touch real repositories, research and writing in the same loop, and no five-hour wall forcing the whole operation to stop just when it gets useful.
The surprising part is that I still cannot seem to use up my $200 ChatGPT account.
My actual July ledger
I used my original capacity last month. Since then, I have already received three additional weekly resets showing July expirations. I keep at least one or two GPT-5.6 Sol Ultra conversations ripping most of the time, and the account keeps giving me enough room to do real work.
Meanwhile, I have three $200 Claude accounts and no problem going through those resources. Fable can still be excellent. Claude still has work it handles beautifully. But excellence inside a narrow window is not the whole product when I am trying to keep multiple hard projects moving all week.
This is the part that model comparisons usually miss. The model is not only the answer at the end of a prompt. It is the amount of context it can carry, the quality of its agent decisions, how long it can stay attached to a goal, how often I have to restart the work, and whether the subscription has enough usable compute for the way I actually build.
On that scoreboard, ChatGPT is winning this round for me. But winning the capacity and production comparison does not mean replacing Claude.
The winning setup is still the combination
I still like Claude and Codex together. Claude gives me another strong way into a problem; Codex gives me the sustained production loop and enough room to stay with the work. The combination is still better than pretending one system has to do every part of every job.
What changed is the amount of duplicated Claude capacity I need to keep that combination productive. Better production from Codex, fewer forced stops, and the extra resets mean I do not have to brute-force continuity through three separate $200 Claude subscriptions.
In my own workflow, I am getting the same results I was getting in the earlier 4.8/5.5 era. The output did not disappear. The account math changed.
Generosity became a capability
OpenAI's public release explains the machinery behind Sol Ultra: more compute and coordinated agent work for difficult tasks. What the release page cannot capture is the psychological difference between rationing every strong run and being willing to hand the agent the entire ugly problem.
When the allowance feels abundant, I stop saving the best model for a perfect prompt. I use it for the messy middle: inspect the shared checkout, recover the history, read the sources, make the change, run the tests, catch the contract drift, and stay until the result is defensible. That produces better work because I am not constantly redesigning the task around the fear of a limit.
The absence of that five-hour interruption matters. The extra weekly resets matter. The fact that I can keep more than one serious lane moving matters. Generous resources are not separate from agent quality anymore. They are what make the agentic ability usable.
The subscription decision
Unless Claude changes materially before the end of this billing cycle, I am planning to reduce from three $200 Claude accounts to one $200 account and one $100 account.
That is consolidation, not abandonment. One $200 Claude account and one $100 account still leave serious Claude capacity in the combination. The difference is that I no longer need three $200 subscriptions just to maintain the same production result.
I am paying for the ability to finish hard work. Right now, ChatGPT is giving me more sustained room, a stronger agent loop, and more confidence that the model can hold the difficult parts without needing the whole job broken into tiny defensive pieces. Codex can carry more of the production load while Claude stays available as the complementary system I still want in the loop.
Claude does not have to become bad for that decision to make sense. The competition can move because one product becomes dramatically easier to trust at full operating speed.
What I want Hugin to preserve
This journal should stay exactly what it is: my observed July ledger, not a universal plan comparison. Another account may see different resets. Another operator may value different strengths. Provider terms can change faster than a billing cycle.
But personal evidence is still evidence when it is labeled correctly. I know how many accounts I am paying for. I know which limits I keep hitting. I know where I send the work that scares me a little because it is broad, expensive, and easy to get wrong.
This month, I am still using both. What is moving to ChatGPT is more of the production load. What is shrinking is the duplicate subscription footprint. That is the more precise version of saying ChatGPT is winning this round.
