make a new programming language:
1. sound type system, like Rust
2. compiles as fast as Go
3. looks like TypeScript
4. green threads
5. embeds anywhere
6. ??

BAML now goes brrrrr
Damn @HarivanshRathi came here to cook 🚀
BAML compiles to both Rust and its custom BEX VM bytecode.
BAML used to be in the same league as Python when it comes to perf, but it's only a matter of time till it plays in the same league as Go⌛️
thx jev

Types Beyond Decisions: box
We’re also releasing a new type that is somewhere in the gray area of decisions: a single bounding box. We warned you there’s a reason we call them System One Models!
(only on jev-preview)

a stricter flavor of TypeScript you say....
Replying to @jarredsumner
Generally, ahead of time compilation results in slower peak JavaScript execution than just-in-time compilation.
We think a stricter flavor of TypeScript and locking down modifications to builtins like Array & Object can close most of the gap.

I think we’re looking for this

No comment.
We really do earnestly believe BAML could kill all programming languages! I personally think it is >10% within the next decade. I believe @boundaryML is trying its best, but we do not yet have a plan to solve alignment and are not clearly on track to.

i know for some folks this is peanuts, but its so cool to see that in the last 48 hours at least 75 people were watching @dexhorthy and I yap on youtube every hour. love you all <3

new benchmark for tool calling... gpt-oss-20b tops out gpt-5 mini (no fine-tuning)
full results coming out soon in a blog post!

running background tasks that just "do helpful things" is so nice.
we now have a package that anyone can use for syntax highlighting BAML that auto updates whenever the grammar changes.

AI is writing more code than you will ever read, but if you don’t understand how it works, its not going to end well.
To understand the code, trace everything, because you can’t know what is possibly going to be useful in the future, and you’re going to be darn happy you have the log.

Replying to @davidcrawshaw
Why would untyped be better? Wouldn’t you want compiler errors before runtime errors? And then leave runtime errors for logic state. (Ofc assuming a fast compilation time)
Reading local code would be harder for both humans and agents without type information
Boundary retweeted
agents deserve their own programming language.
@boundaryML is already doing this incredibly well with BAML. Ive genuinely been loving it so far
super excited to be in seattle this week w/ the team~
I’ll share my insights & thoughts on BAML throughout the week!

Sharing a preview of our new programming language built with AI agents in mind this Thursday. Only 20 spots.

Someone really wants our promptfiddle.com api keys... here let me make your life easier.

Meanwhile, promptfiddle is now BYOK :(
lets go!!
One week out: Seattle Rust User Group meets Thursday, June 18 at 6pm PT, hosted by @boundaryML.
@conradirwin from Zed is in town to talk CRDTs, alongside talks from @boundaryML and the local Rust crowd.
Excited to see you there!

At @boundaryML We're building building a full compiler, VM and async runtime.
Kinda like TypeScript + V8 + Node.
marginally manageable is the highest form of flattery
Replying to @djpsychofogbear @Jonathan_Blow
5/x: and then use @boundaryML 's BAML for chunking things out and testing / iterating quickly. fuck llms and prompts etc but if you have to work with them BAML is like the only thing that makes it feel marginally manageable.

We are launching a programming language built for agents soon called BAML that has been in the making for 1+ years. You can follow @boundaryML
We are a small team of 6 developing it with care, gathering feedback from humans and agents.
Fully Open Source.
If you are interested DM me for early alpha access.
