Developer of 20+ years here, can't give you an accurate multiplier but I am faster.
Because spotting holes in specs has never been one of my strengths. And working without technical colleagues much of the time, it's a boon to be able to "rubber-duck" my ideas with something that is at least more intelligent than plastic.
Grabbing multipliers from thin air, the coding bit may only be 2x faster with a poorer-quality outcome, but working out what's needed is a good 5x faster.
And yes, I'm using the same adversarial AI MO as @wood_spirit, combined with Matt Pocock's excellent /grill-me and /grill-with-docs skills [1] and Plannotator [2] to review the plans.
I actually use LLMs a lot to rubber duck my problems and help develop plans. Then I manually code, to ensure my skills don't deteriorate. I feel like I'm a lot faster, with few of the downsides. Do you have any thoughts on this process?
If you can type code fast and accurately, it sounds a great process to use. You're using LLMs for the bit where they bring great value, and yourself as a higher quality coding agent :)
Can't speak for GP or OP, but I see about 10x the output and 2-4x the value of what I would be able to get by hand. Within the gap between 2-4x and the 10x is really a lot of design documents, user/dev documentation and testing that I might not have rolled to nearly the extent that I do/get when using AI.
I haven't been using multiple AIs adversarially as OP, but might consider giving it a try with Codex and Opus. That said, my AI workflow has been pretty similar... lots of iterations on just design, then iterations on documentation, testing, etc... then iterations on implementation, testing, validation and human review in the mix.
My analogy is that it's really close to working with a foreign dev team, but your turnaround is in minutes instead of days, where it's much more interactive.
Having tried something similar, the perceived speedup does not, in the steady state, last.
To get a quality, lasting, result you're ultimately having to carefully study everything otherwise you end up quickly accumulating cognitive debt and the speedup soon shrinks as you're constantly having to revisit the initial approaches.
I use the latest codex with gpt5.4 and Claude opus every day. they hallucinate every day. If you think they don't, you are probably being gaslighted by the models.
I use linux at home (with a HiDPI screen) and MacOS for work. The screen works well with both computers. I mostly just use a text editor, a browser, and a terminal though.
Linux has bugs, bug MacOS does too. I feel like for a dev like me, the linux setup is more comfortable.
Same here. I stick to 100% scaling and side step the whole hi dpi issue. I even have a single USB type c cable that connects my laptop to the laptop stand and that laptop stand is what connects to the monitor, keyboard, and mouse.
I know people will say meh but coming from the world of hurt with drivers and windows based soft modems — I was on dial up even as late as 2005! — I think the idea that everything works plug and play is amazing.
Compare with my experience on Windows — maybe I did something wrong, I don't know but the external monitor didn't work over HDMI when I installed windows without s network connection and maybe it was a coincidence but it didn't work until I connected to the Internet.
I use a fork of sqlx in SQLPage [1]. I think my main complaint about it is runtime errors (or worse, values decoded as garbage) when decoding SQL values to the wrong rust type.
