If Anthropic wants to own code development in the future, owning the full platform (including the runtime) makes sense. Programming languages all are a balance between performance/etc and making it easy for a human to interact with. This balance is going to shit as AI writes more code (and I assume Anthropic wants a future where humans might not even see the code, but rather an abstraction of it... after all, all cod…

"the full platform" there are more languages than ts though? Acquisition of Apple Swift division incoming?

I think there's a potential argument to be made that Anthropic isn't trying to make it easier to write TS code, but rather that their goal is a level higher and the average person wouldn't even know what "language" is running it (in the same way most TS devs don't need to care the many layers their TS code is compiled via).

Bun is such a great runtime. If you haven't tried it, try it. It's got bells and whistles.

This will make sure Bun is around for many, many, years to come. Thanks Anthropic.

Why Bun?

Easy to setup and go. bun run

Bells and whistles. (SQL, Router, SPA, JSX, Bundling, Binaries, Streams, Sockets, S3)

Typescript Supported. (No need to tsc, bun can transpile for you)

Binary builds. (single executables for easy deployment)

Full Node.js Support. (The whole API)

Full NPM Support. (All the packages)

Native modules. (90% and getting better thanks to Zig's interop)

S3 File / SQL Builtin. (Blazingly Fast!)

You should try it. Yes, others do these things too, but we're talking about Bun.

What is the business model behind open source projects like bun? How can a company "aquire" it and why does it do that? In the article they write about the early days We raised a $7 million seed round Why do investors invest into people who build something that they give away for free?

The post mentions why - Bun eventually wanted to provide some sort of cloud-hosting saas product.

Quote from the CEO of Anthropic in March 2025: "I think we'll be there in three to six months where AI is writing 90% of the code and then in 12 months we may be in a world where AI is writing essentially all of the code"

Do you have a source for the quote?

So many comments about reasoning here, yet none about the very obvious one, it's not stability of the infrastructure, it's future direction of a product like Claude Code. They need to know how to continue their optimisation machine to fit developers needs the best way possible (for good or for worse).

I guess we should wait for some opt-out telemetry some time soon. It'll be nothing too crazy at first, but we'll see how hungry they are for the data.

If I had the cash, I could sell dollar bills for 50 cents and do a $7b run rate :)

If that was genuinely happening here - Anthropic were selling inference for less than the power and data center costs needed to serve those tokens - it would indeed be a very bad sign for their health. I don't think they're doing that. Estimates I've seen have their inference margin at ~60% - there's one from Morgan Stanley in this article, for example: https://www.businessinsider.com/amazon-anthropic-billions-cl...

The leaders of Anthropic, OpenAI and DeepMind all hope to create models that are much more powerful than the ones they have now.

A large portion of the many tens of billions of dollars they have at their disposal (OpenAI alone raised 40 billion in April) is probably going toward this ambition—basically a huge science experiment. For example, when an AI lab offers an individual researcher a $250 million pay package, it can only be because they hope that the researcher can help them with something very ambitious: there's no need to pay that much for a single employee to help them reduce the costs of serving the paying customers they have now.

The point is that you can be right that Anthropic is making money on the marginal new user of Claude, but Anthropic's investors might still get soaked if the huge science experiment does not bear fruit.

Why would they want to bet on nascent technology whereas Node.js bas existed for a god 15 years?

Because they needed something that could produce a single binary that works on every platform. They started shipping Claude Code with Bun back in July: https://x.com/jarredsumner/status/1943492457506697482

They could use the Node.js equivalent: https://nodejs.org/api/single-executable-applications.html#s...

As someone who have been using Deno for the last few years, is there anything that Bun does better? Bun seems to use a different runtime (JSC) which is less tested than V8, which makes me assume it might perform worse in real-world tasks (maybe not anymore?). The last time I checked Bun's source code, it was... quite messy and spaghetti-like, plus Zig doesn't really offer many safety features, so it's not that hard t…

I’ve been using Deno too. Although npm support has improved and it’s fine for me, I think Deno has more of a “rewrite the world” philosophy. For example, they created their own package registry [1] and their own web framework [2]. Bun seems much more focused on preexisting JavaScript projects.
