From the release video, something catching my attention:

> In Bun 1.4, I rewrote Bun in Rust. [...] I did it in 11 days, using Claude Code, and wrote about how, in our blog.

Everything else in the video is phrased as "we", and even the section in the blog post is "We rewrote Bun in Rust"[1].

There's no question Jarred did the work and deserves enormous credit for it. I just found the contrast interesting, because the video explicitly frames the rewrite as "I", whereas the rest of the release frames it as "we".

While it has been used by Anthropic, the main question is if it works in other Bun's 1.3 production settings. Ignoring all the improvements, if it does work and no major bug or problems occurred, We are in for some management top down "Rewrite it in Rust" action over the next few years. And perhaps even worst, management will believe in Claude feed into Claude development.

This isn't so much about Bun or Node.js any more. It is the battleground for AI and non-AI coding.

omfg, that's a long post. How is this even possible? I know we're all using AI, but Bun seems like the one singular project where there's just been a crazy increase in the amount of output, a 10x on the 10x. How are they doing this?

Unlimited full-access to one of the best LLMs / agents on the market, and 80 hour work weeks probably.

I think this was to contrast with the multi-engineer effort the task would normally be.

It's weird their promotional video repeats "you can do without installing dependencies", if I want headless browser testing is that wrong to install a project that offers that? Why would I want everything reimplemented in this massive binary? Why would Bun be anymore in touch with nuances of all these different technologies then individual projects dedicated to their own speciality? JS Runtime, Package Manager, Test…

I always thought Bun's approach was to be the JS runtime with a large well-designed std-library, this isn't really new. It's nice to have a choice of a more or less-featured runtime depending on the project's requirements -- if size and complexity are an issue, there's a variety to choose from.

Also, access to models the public doesn't have, he had full Fable 5 in May.

Jarred spins it as "pre-release" [1] but it was pre-embargo.

He likely had unlimited access to unrestricited Mythos in May, which is even better than Fable.
