“Funny enough, I sent this one from voice to text on my iPhone as I was getting my hair ready in the bathroom before stream because I wanted to have it ready to use if I wanted to demo it during stream.”

“This is a podium mic. I did not think I would ever want one of these. Not only has this fundamentally changed how I use my computer, I forced my whole team to try it and every single one of them ended up buying one of their own and I bought them one for the office as well.”

- Blender

“In particular, when you give it Blender access and tell it to create something like this, it's so far ahead in this type of 3D design work that it's unfair to even compare to other models.”
Coding software42
- T3 Code
cited in 25 videosspeaks highly of it

“By default, T3 code auto settles threads that you have not touched for at least 3 days, which I think's the right call. I bumped it to seven cuz I usually have better discipline about clearing out my inbox, but I'm not good enough at it here, which is why my sidebar is a little chaotic.”
- GitHub
cited in 15 videoscritical of it

“I'll be real with y'all. A lot of my problems with Git are coming from GitHub because it's just a slow and miserable platform.”
- Claude Code
cited in 13 videos

“And despite the fact that I'm using Opus and Claude Code right now in T3Code, which by the way uses your actual Claude Code with your actual Claude Code sub, this will now spin up with T3's built-in orchestration all of these other agents using their native harnesses.”
- Codex
cited in 8 videosfirst cited August 2026positive about it
“If I don't want to sit there and download all my medical records for my surgeries, I don't ask my assistant to do it like I used to, I ask Codex to go through my inbox and go through all of my dashboards for my medical on my browser and get it all for me.”

AI software62
- Opus
cited in 14 videoscritical of it

“I fell for Opus 5 when it came out. It seemed like it was working really well. But when you combine the absolute slop it would output in text trying to describe what it was doing with the code that would often miss really important stuff, the model felt more like a liability than an actual thing you could rely on when you worked every day.”
- Soul
cited in 14 videosspeaks highly of it

“The reason I so strongly believe that this feature porting works well is because the app I'm using every day for doing my code on my phone is a Swift UI port of the React Native app that I built 95% with Soul and like fiveish to maybe 10 now with Astra that I built in a single thread, one thread for almost the whole app.”
- Fable 5.1
cited in 10 videosspeaks highly of it

“While I think Claude Opus 5 is ranked way too high on this, I would honestly say Fable 5 is ranked a little low because the gap between Fable and Soul feels very real in my day-to-day usage and Fable 5 is still my preferred model for actually writing and landing code in real projects.”
