The happy ending :)

[Theo - t3.gg @theo]

In the 24 days since Opus dropped, I shipped...

- I built ts-rust, a complete rewrite of the Typescript Compiler in Rust that is 2-3x faster than the official version

- Got 245 prs into T3 Code, an AI coding app with over half a million users. I shipped over 60 PRs in the last 48 hours alone.

- Created Slopalytics, a better model bench site with data from Artificial Analysis and T3 Code

- Started Slophouse, my new internal Clickhouse db for managing the anonymized usage data from T3 Code

- 46 PRs into Lakebed, my cloud for building apps with agents

- Over 1,200 commits into lust-lang, a subset of Rust that compiles 100x faster

- Started fckbench, t3os, and more I'm forgetting

Rough estimate is 22 years of work, in 21 days.

Is all of this real stuff that will ship to users? Absolutely not. But a lot of it is.

Now who can get this done with a 27b model on their GPUs at home? :)

Sol completes the tasks less than 5 percentage points off Opus, but at less than a tenth of the cost!! $0.80 vs $10.53. Incredible performance from @openai 💪

@theo you will really make me install the Nightly.....

New branding for T3 Code: "We burned the tokens so you don't have to"

We've probably burned $10m+ in tokens collectively just contributing to T3 Code

People seem shocked that the author of Clean Code doesn't read code anymore. But that should not be surprising.

Why did I write Clean Code? What is the goal of keeping code clean? To get it out of the way of the real job -- thinking.

GPT 6 Luna is literally cheaper than DeepSeek V4.1 Flash. We're so back

[OpenCode @opencode]

GPT 6 Sol, Luna and Opus 5.5 now available in OpenCode

[dax @thdxr]

in the next version of opencode2

you can connect multiple accounts for the same provider and switch between them

if you use this against me i will be mad

@narcelio Cara comentei a mesma coisa hahahaha… galera tá vivendo em outra dimensão

[Douglas Mendes @DougTheDev]

15 years working in software development, and I’ve never seen a single codebase that actually looks like the image on the right: perfectly clean, beautiful, and with every single thing organized 😂

I really understand the criticism around vibe coding, but come on… the image on the right is not even close to the reality of software engineering hahaha.

[Douglas Mendes @DougTheDev]

I think you guys mostly disagree on the scale. Large software systems are extremely hard to keep entirely in your head, and no human can retain every detail.

That’s exactly why we build abstractions, split systems into modules, define boundaries, and reduce cognitive load into chunks that humans can actually understand and maintain.

I watched the video, and I think he makes a good point.

[Douglas Mendes @DougTheDev]

@NickADobos @theo Based!

[Nick Dobos @NickADobos]

@theo Yup. Brains don’t scale to codebases.

You cannot expect to keep all code in your head. Especially in a team environment.

Navigating the labyrinth of code others have built, (including past you) is a core part of the skill of software engineering

This is Fire 🔥

[Theo - t3.gg @theo]

If you understand your whole codebase, the codebase isn't that important.

Real software is larger than what your brain can comprehend.

GPT-6 Astra × Higgsfield:

OpenAI's strongest model yet for coding, reasoning, and complex knowledge work, paired with real-time 3D generation.

You can build a playable game from a single prompt: mechanics, story, and every asset generated by Higgsfield MCP.

Coming soon to Higgsfield.
