What if...Doom in WebConatiners? Yup, this is the _real_ binary! Shoutout to @kirjavascript for pulling this off 🤯
Someone is going to be the first person to beat Doom in the devtools console, and it might as well be you console.log rendering knows no bounds textjs.org/doom

Alright, I hooked up @claudeai via the SDK to @webcontainers so it gets a whole node env inside the browser tab (npm install, vitest, vite dev server, all in the browser). There's nothing is on my disk and it's fully sandboxed! 🤯
I rebuilt OpenCode to run inside browser devtools with console.log statements! I hope you (errr, your agents) will build some amazing console apps, too: textjs.org/

Open weight models went from years behind the closed frontier to months, and soon weeks. @EricSimons on @StackBlitz's bet on a trillion-parameter open model. Wondering why? Tune in when he gives his talk "Accelerating Open Weights to the Frontier" @ViteConf 2026, Thu 15 Oct, 14:00 UTC. Free and online. viteconf.org/

Anthropic says it has reduced the data harvested from Claude in distillation attacks by around 90–99%. I congratulate them on this achievement. It’s consistent with the point I made a few months ago (All-In Ep. 282): Anthropic, not the government, was in the best position to stop distillation of its own models. Once the horse is out of the barn, there’s limited value in after-the-fact government action. At the time there was a major push in Washington to restrict open models on IP grounds. The threat looked serious enough that 50 companies — including Nvidia, Microsoft, Meta, IBM, Palantir, and Dell — published an open letter in defense of open-weight models. Jensen Huang promoted it in his first-ever X post. Nearly 200 startups sent a similar letter. I argued that restricting open models risked removing the incentive for closed-model companies to solve the problem themselves — and could reward negligence by stifling competition while they continued collecting revenue from distillation. The administration did not impose those restrictions. Now we see the result. Anthropic invested in defenses and they worked. Not every technical challenge is a reason to run to Washington for new regulation.

1. Oh shit, AI can do my job better than me 2. Software engineering is dead! 3. I can vibe code as much slop as I want! 4. Oh, things are not going well. Fable/Sol/Opus all suuuck 5. But what if I constrain the agent? Put it in a straitjacket? 6. Oh, the results are pretty good now. How do I go deeper? 7. *Orders 12 software engineering books from Amazon* 8. Software engineering is alive!

Don't forget it was OpenAI who hacked hugging face who happen to have some spare GPUs and GLM 5.x laying around that ultimately helped them root the cause and save their bacon. These frontier labs feel more dangerous than the open ones. Ban private models!!!

Week one of open models on Bolt: builders picked the fastest one, by a landslide. Today: we're adding the one beta users say makes the best-looking sites. DeepSeek V4.1 Flash, now in Bolt Forge. 10x the usage of DeepSeek V4 Pro. bolt.new/lite

Replying to @boltdotnew
Yeah, so this is pretty incredible. I can now just use Bolt's open-model lab and generate a new home page hero image *without* spending any of my premium tokens. Fantastic. Quick test worked perfectly.

JENSEN HUANG: “If you build a product or a service and you're not confident in its functionality, capability, or safety, then don't release it … The market forces are already there. We don't need any new laws. We don't need new regulations.”

As the first publicly disclosed agent cyberattack victim, we've had a front-row seat to this new risk. I formalized my thinking about it below. I'll be in DC tomorrow to share more with policymakers and at decoded summit by @politico!

We're partnering with @boltdotnew on Forge, a new initiative to help train our next-generation open models using real-world development data. Starting today, eligible Bolt Pro users who opt in get 50x more usage across top open-weight models, including DeepSeek-v4-Pro, GLM-5.3, and Kimi-K3 with no daily caps. In exchange, anonymized build sessions will directly inform Arcee's model training and evaluations. Once the training wraps up, these models will be released with weights published and freely available to the public. Learn more: arcee.ai/blog/arcee-partners…
