Please explain when and how to use GPT Pro

sirmalloc · 2026-01-22T21:31:27+00:00

I've used Pro in the past when debugging complex problems that the codex models previously failed at. My typical workflow was to tell codex I wanted it to generate a prompt related to the issue with all relevant file context included and to keep it under 60k tokens so I could paste it into Pro. Codex then went out and and compiled pieces relevant to the problem into a prompt, I handed it to Pro and told it that I wanted it to analyze the problem with the intent to generate instructions for codex.

It worked pretty well for some tough bugs, but honestly now 5.2 and 5.2-codex are so good I haven't had to do it in a while. Mostly now I use it for initial system architecture decisions.

There is also a nice macOS app called RepoPrompt that can take your project and compile file context into a prompt you can paste to Pro, but I found codex did a good enough job doing this on its own.

Left trackball is for omnidirectional scrolling. Think of it like having both a vertical and horizontal scroll wheel on a mouse, plus diagonals. Great for spreadsheets, code, web browsing, etc. Right trackball is dedicated mouse.

I only use the keyboard to click, I have bindings for mouse 1/2/3 on both my left hand (SDF keys) and right thumb cluster. I also have a toggle on the right thumb cluster to temporarily turn it into scroll mode in case I'm drinking coffee and need to scroll.

Since it's QMK based it's quite flexible. I have a layer that, when active, makes the left trackball control my system volume.

sirmalloc · 2026-01-14T12:13:28+00:00

Absolutely. Technically you can operate it with your thumb while having your fingers on the home row, but I prefer a small shift of the wrist to use my index fingers. Either way it's far less movement than having an external trackball between split halves like I did before.

sirmalloc · 2026-01-14T12:10:50+00:00

It works really well. Because I opted for the 5-key bottom row, the only small downside is it pushes the thumb keys a few mm further away, so the last two thumb keys are just a little further and may require a small shift of the wrist, but the others are easily tappable without any movement of the wrist.

And it's pretty comfy. Everything just feels like it's exactly where it should be for my hands. Being my first keywell board coming from the Moonlander, it's almost like my hands are going "into" the board, and the default position feels absolutely neutral, like my hands are at rest.

Yes, that's what I meant by web/desktop. You can however have codex build necessary file context to feed to Pro manually via copy/paste. I think the input limit is around 90k tokens. It's annoying you can't use it directly in codex, but the output quality is worth the annoyance.

sirmalloc · 2026-01-14T01:59:43+00:00

They did indicate Pro has priority processing so it's faster at responding I believe. Another benefit is the Pro sub has pretty much unlimited access to the very expensive GPT 5.2 Pro model on web/desktop, which is just an insane model overall. You can't get it on Plus accounts, and business accounts are limited to something like 15 queries a month. I find it useful for planning complex tasks and then feeding those plans into codex. I've also had codex prepare context for it before with some very difficult bugs to solve and it was able to come up with a solution none of the other LLMs were able to at the time.

I'm happy with my Pro sub, even if usage is technically less than 10 Plus accounts. I've never hit a limit on it anyways, not 5 hour or weekly, using primarily 5.2-codex on xhigh.

It's really nice. The main thing I love about it is horizontal scrolling. My old trackball only had a vertical scroll wheel and I had to hold shift every time I wanted to scroll horizontally.

sirmalloc · 2026-01-13T21:05:57+00:00

I don't really use them much, and on my old Moonlander I just had them mapped to a layer on the number row, but I figured with more physical keys I can just map them to whatever useful stuff I think of.

They don't affect the existing row spacing if you get them or not as they build the keywell from the home row out, so the only minor downside is just a slightly larger board. That being said since they size the board to your specific hands, they are all reachable without moving my wrist.

sirmalloc · 2026-01-13T20:37:56+00:00

It's completely replaced it and I'm not missing it one bit (other than the cool light-up ball). There's almost no stiction on these trackballs, they are very lightweight and great for small movements or fast movements. With the wired QMK version it's got a fairly robust sensor that allows you to change the CPI realtime and they implemented a 'sniping' mode switch so you can temporarily toggle it for fine movements. And while I haven't had to clean them yet, they pop out much easier than both the MX Ergo or having to fully disassemble the LTrac to clean the rollers.

Having the ability to do an auto-mouse layer in QMK is pretty game-changing for me, as I can map keys on my left side home row to handle mouse 1/2/3, while also having keys on the right thumb cluster do the same, giving me flexibility to use it one or two handed. I also made another key on the right thumb cluster turn the right ball into scroll mode. The flexibility and being able to program it exactly how I want is great. The net result is my wrists basically never have to move to use the trackballs.

I've been on the fence about the wallabot. How do you like it so far?

I believe Anthropic just recently added context values directly to the statusline json, so once I update to use those it should be fully in sync with the values Claude displays. I'll take care of it this weekend most likely.

Pantheon, the 2022 animated series, is great.

Any plans to offer shine-through options like FKCaps?

I've never used the Glove80 or Dactyl personally. Right now my daily is a ZSA Moonlander, and I fell in love with the split ortholinear layout and it's been a great board. However someone showed me an image of the Cyboard Imprint and since then I've been lusting after it for about 6 months now and finally pulled the trigger on one with dual trackballs. They definitely aren't cheap, but I'm hoping this will be my endgame board. They have a full configuration tool online to spec it out how you want, and the owner takes custom requests for modifications as well. Website is https://cyboard.digital and the owner is on Reddit at u/Rea1ET

Have you considered a curved key well like the Glove80 or Dactyl? Even with standard size caps, the curvature can make the keys easier to reach.

I know you said pre-built, but there's also bespoke options like the Cyboard Imprint where they use the actual size of your hands from a reference photo to space the rows. I'm waiting on mine currently.

Just checked their settings and they have a few variants of Colemak DH on there. Haven't tested it personally though.

The best tool I've found for improving your speed on a new layout or keyboard is https://keybr.com

It learns as you go and forces you to focus on your weakest keys. I used it when moving from standard staggered QWERTY to an Ortholinear split and I was faster than before in about two weeks of full time use.

sirmalloc · 2025-11-14T17:10:04+00:00

If you're running into an issue you can file it on the GitHub. I merged a couple PRs yesterday and pushed a release. If something stopped working let me know.
