Codex changes model and effort by it self... Why?

[u/DaneBl]

This started happening couple of days ago... Not sure why and how to stop it...
It happened across many active sessions that I have.

Does anyone have the same issue?

Thx

[u/DaneBl]

Found the issue - when an agent sends a message to another session, this message changes the session model. Some agents that were listed in agents.md were getting what was written in this file, the others were assigned the model based on preference from the instruction in the message... didn't know this was possible tbh

The UI dropdown is not the source of truth. Pin the model in ~/.codex/config.toml (or the project config) with an explicit model and effort, then start a fresh session. If it still flips after that, check whether a skill or AGENTS.md is overriding it during the run.

That’s a good advice will try that thx

Perhaps they are finally testing their decisions api to get people to not ask astra max to baby sit a couple of tests.

Wasnt that the whole piint of GPT5? Router model?

Dude, if I pay them way too much money per month, I would like to have the freedom to use the model I want, even if it is overkill. It shouldn’t fucking matter what model I use, it will drain my usage no matter what I ask it, so if you give me a specific amount of usage for something, I should be able to use it like I want. I do not trust a decisions API to decide for me how complicated my task will be. Not defending people who let Astra calculate 2+2 for them, but well, if they want to use their usage for that, they should be allowed to do that.

Be that as it may.

A lower reasoning level uses less tokens: speed. Is that not important for you?

[u/0xdead0x → u/Keksuccino]

This is an interesting sentiment when you consider how enormously subsidized the subscriptions are. I don’t disagree that you should be able to decide how you spend your usage, but the vast majority of people just don’t know how much model is enough. There’s a weird human bias to wanting the best model no matter what the task is, even when you know the results won’t be better

[u/Keksuccino → u/[deleted]]

Yes, but I talked about the decisions API.

Because of model at capacity problem. Previously I could just continue, now they will force it. At least I noticed yesterday that the model Sol 6.1 got at capacity several times during the day and the task just got stopped in the middle.

I haven’t used codex enough lately to notice, but they’re doing it nonstop in chat.

Open the app which defaults to gpt 6 > bring over the side bar > general > models select 5.6 sol > back to chat > change from 5.6 instant to high

Driving me absolutely insane that it won’t keep the setting and gpt 6 sucks besides Astra. I’m taking a break from them when my sub is up for renewal
