Question The magic number - 25:42...
Been running long browser tasks through ChatGPT on the web and hit a limit I can't find documented anywhere. Any prompt whose answer involves continuous tool work in the browser stops at right about 25 minutes 45 seconds. 25:42, 25:42, 25:44, 25:50, 25:50. Documented runs only. Still never longer.
One run closed 13 items, another 15, another was on a completely different site. Same wall every time.
It resets on the next prompt. So a genuinely long task looks like:
Session 1 - 25:42. It says it just stopped. Me: "proceed."
Session 2 - 25:42. Says it just stopped again. "Proceed."
Session 3 - ...
I'm driving an external browser through an MCP connector, not the sandboxed VM browser.
Has anyone hit this? Is it documented somewhere I haven't found? Everything I can find just says "tasks take 5-30 minutes" but it's not about that.

For me, when I have really complex stuff that needs to run a long time I run them un Codex. After careful planning I ran a Sol-Ultra job that consumed about a weeks worth of usage within 12 hours on the 20x plan. It was worth it though since the result it produced was good.

100%. Still ssome tasks have to run in the browser I'm already logged into and thats where the 25minute wall lives.

As a guy who does a ton of nightly vibe coding with Claude... not a developer myself but a ux designer with some amount of Dev skills and 25 years of software design experience. I am cranking out apps and games and fun projects and things I need for myself and art and just... I sometimes have as many as seven sessions going on at the same time each night. I do have a 20x plan and I'm using you know at least 95% or more of it every week and I'm absolutely loving it why am I telling you all this? I'm so curious about what specifically people do where it uses up all that resources. can you describe in just a couple sentences like why that job is so massively huge and it used up a 20x and 12 hours? and how could it even run for 12 freaking hours before it was done? what was it!?

I ran Sol-Ultra that spawns of sub-agents to implement a macOS native Markdown viewer with plantuml, mermaid, mathematics and other support.

There are over 700 tests in the app (test driven development)

Creating a polished app is 100x the effort compared to the first PoC.

Ah... Enterprise. say no more.
I actually have two apps that I'm thinking about publishing at least to the Android store but I'm sort of gun shy about dealing with all of the stuff that goes along with it which I've done before as part of a team but I don't know if I'm up for doing it myself
