I am not a fan of Theo @theo but I tried T3 code after using claude and codex app and honestly it's the best. It solved my remote control problem on my wsl and vps...
We just shipped in-app visualization capabilities in T3 Code. This enables agents to build cool dynamic experiences within the thread.
Huge shoutout to @davis7 for pushing us on this (and building most of it). Didn't expect to dig it so much.
getting started with T3 Code has never been easier, excited to be a launch partner of Sign in with ChatGPT!
install t3 code, sign in to your ChatGPT accounts (yes… plural, t3 code supports multiple accounts), and send your first prompt. no external dependencies required.
available now on latest t3 code!
prolly should have left a link to the docs for existing users who dont get the fancy onboarding huh...

Huge T3 Code release just dropped. Over 380 changes. Quick highlight reel of my favorites:

- `npx t3 connect` support on Mac (run 1 command to make a Mac into a remote dev machine)
- 93.8%+ performance improvement for rendering long threads
- 80%+ reduction to data transferred and stored for threads
- In-app terminal performance overhaul
- Remote server upgrades are 5x faster and 100x more reliably
- Remote projects can now be opened in VS Code via ssh with 1 click
- OpenVSX support for custom themes! Use your favorite VS Code themes directly
- Codex skill discovery is way more reliable
- OpenCode skills actually appear in app now
- Claude can discover project-level skills now
- Fixed really annoying auto scroll behaviors and edge cases
- Claude Code compaction recommendations now surfaced in app
- Codex permission requests for MCP/ComputerUse stuff now surfaced in app
- Tons of improvements to Windows app
- More polish than I can fit into one tweet
Sorry this release took so long. I hope it was worth it. Check out the nightly builds if you want to get these features when they're (mostly) done instead of waiting for us to cut a stable release 🫡
