I had high hopes for the new Opus release. It massively exceeded them. Opus 5.5 is an incredible model.↗

Jev is incredible. I'm scared people are using it wrong.↗

Mario (creator of Pi) thinks this video is worth watching. He's smarter than me so he's probably right. (It's about memory in code tools, and it features a crash out at how bad Claude Code's memory is)↗

Small new feature I just snuck into T3 Code's server package. `npx t3 pair --tailscale` (nightly only for now) Generates a pairing link + QR code for T3 Code. Should make remote setup for Tailscale users 10x easier :)↗

T3 Code is now available on iOS and Android. Run “npx t3 connect” in your terminal, install the app, and now you can control Claude and Codex fully remotely. Still 100% free. Still 100% open source. Enjoy 🫡↗

"npx t3 connect" This one's been a lot of work. You can now set up remote control for T3 Code on any internet-connected box with literally one command. All for free. T3 Connect is a minimal open source tunnel layer allowing you to control T3 Code instances remotely without need…↗

How are we feeling about Opus 5 so far?↗

Kimi K3 is really, really good.↗

gpt-5.6-sol without hitting limits I've burned over $200,000 of tokens with gpt-5.6-sol. It's a great model. That said, it's a bit too easy to hit your limits on the $200 Codex Pro sub. OpenAI has been generous about resets, but that doesn't help you when you kill your 5 hour w…↗

The Codex app is dead, and I am unhappy about it.↗

Over the last month, I burned over $200k in tokens with gpt-5.6-sol. I built a lot. Instead of just reacting to the benchmarks, news, tweets, etc, I went a different route. This video is an overview of all the cool shit I built using the new model. Proper review coming soon™↗

Don't make the same mistakes I did. Here's a video on how to get the most out of Fable, full of real world examples of Fable helping me ship.↗

Codex, Claude Code, and Cursor are all great tools. They're also much more different than you think. I did a comparison of the three, but not in the usual way. I went deep on how they differ philosophically.↗

If you use any of the following with your Claude sub, your usage must got cut by 25x: - T3 Code - Conductor - zed - jean - “Claude -p” in your ci - scripts to call Claude code from other tools They’re disguising this as “free credits”. Don’t fall for it.↗
