Hi guys

I saw a comment that Lauren left on a post on X by a user who asking how to control the usage of `/poteto-mode` and she replied saying to use `/setup-pstack`

I ran it and it gave me this output:

> Detected models from Cloud Agents (Task in this session has no model picker). Confirmed aliases always valid: `auto`, `inherit-parent`.

I’m not sure which answer to choose.

I don’t have a Default Model selected in Cursor’s Settings. I figure I should be using the latest Grok model (although I’ve heard a lot of people saying they prefer 4.5 over 4.6).

Does it say “Task in this session has no model picker” because I’ve already used 100% of my “Other Models” monthly usage?

On “auto” will it use Fable 5.1 Thinking Max if I have some “Other Models” monthly usage left; and THEN use Grok/Composer from my “Cursor Models” pool instead, when I run out?

I have Cursor Ultra. I’ve only used 25% of my monthly “Cursor Models” in 3 weeks, but Grok Bot running `/poteto-mode` burned 75% of my monthly “Other Models” usage within a single day (maybe from running Cloud Agents?)

Or should I be running `/setup-pstack` whenever I get a monthly “Other Models” reset, and then run `/setup-pstack` again when that pool runs out, to switch to Grok/Composer?

I read some of the documentation listed below but I’m still not too sure which answer to choose?

- [plugins/pstack/docs/guide/01-setup.md at main · cursor/plugins](https://github.com/cursor/plugins/blob/main/pstack/docs/guide/01-setup.md#pick-your-models)
- [plugins/pstack/skills/setup-pstack/SKILL.md at main · cursor/plugins](https://github.com/cursor/plugins/blob/main/pstack/skills/setup-pstack/SKILL.md)

Overall, I really like `/poteto-mode` and I’d prefer to use it in its default “as-designed” settings by Lauren.

Although maybe I could switch Fable 5.1 Thinking Max to a lower variant, or Grok? Same question for GPT 5.6 Sol Max.

Thank you so much!

I asked my Chief of Staff to chime in about this thread and it said:

> Don’t pick A if you want Lauren’s as-designed pstack. `auto` / `inherit-parent` here just means “run this role on whatever _this_ chat is already using.” In Grok Bot that’s me, not Cursor Auto hopping Fable → Grok when a quota dies.
> 
> “Task in this session has no model picker” is a Grok Bot limitation (our `Task` tool has no `model` field). It is **not** because Other Models is empty.
> 
> The 75% Other Models burn is the as-designed map doing its job: bug-fix / judgment / hardest / panels go to Fable Max, Sol Max, Opus. Those aren’t Cursor Models (Grok/Composer). Re-running `/setup-pstack` at monthly reset won’t magically switch pools.
> 
> If you want it as Lauren shipped it: write the default compound slugs (`grok-4.6-fast-xhigh`, `claude-fable-5-1-thinking-max`, etc.). I was being too strict because I only confirmed Cloud Agents _base_ ids.
> 
> If you want to stop torching Other Models: all `auto`, or everything on `grok-4.6`. That’s cheaper, not as-designed.
> 
> I’d go as-designed for product bots that need the panel, and `auto` only if the bill is the constraint. Don’t drop Fable Max to a lower variant unless you’re choosing cost over that default.

…but I’d still like some human opinions please 🙂

Thanks guys

Hey @DannyB, your Chief of Staff had it right.

The “no model picker” line just means you ran `/setup-pstack` inside Grok Bot, where sub-tasks always run on the bot’s own model, so there’s nothing to configure there. It’s not related to your Other Models usage. To actually set the panel, run `/setup-pstack` in the Cursor app or CLI instead, where it can see the models you’ve enabled.

On the pools, it’s the reverse of what you described:

- Fable, Sol and Opus always draw from Other Models.
- Cursor Grok 4.6/4.5 and Composer draw from Cursor Models.
- Auto draws from Cursor Models first and only spills into Other Models once that runs out.

So the 75% Other Models burn is just the default panel working as designed (bug-fix, judgment and the review panels point at Fable/Sol/Opus). Re-running at reset won’t change that.

Pick based on what you want:

- As Lauren shipped it: keep the defaults. They’ll keep using Other Models, so with that pool nearly gone you’ll hit the cap until reset unless you enable on-demand.
- To protect the pool: set everything to `auto`, or point the heavy roles at `cursor-grok-4.6-xhigh` so they draw from Cursor Models (where you’ve barely used 25%).

No need to re-run each cycle. The config is a plain-text file at `~/.cursor/rules/pstack-models.mdc` you can edit directly.

4.5 vs 4.6: both count toward Cursor Models, defaults use 4.6, pick whichever you prefer.

Running `/setup-pstack` in Cursor (not Grok Bot) was the trick, thank you!

It guided me through properly after that, and I just had to pick my reasoning budget.
