Sley 2.1.5 just dropped 🚀 Up to 2.9x faster than the last release. It now beats Python on 3 of 5 speed tests, ties on another, and starts 6x faster. And when AI writes and fixes code, Sley burns fewer tokens than Python, C, Rust, Go or TypeScript. sleylang.org

The excuses to not use #SleyLanguage for all your vibe coding needs are running out! Big breakthroughs for Sley!

A Sley commit leaves a receipt. The transaction stages and verifies immutable objects, syncs the evidence to disk, then advances the head atomically. Every accepted change has a specific state to inspect. sleylang.org/tutorial

Let's see, ZJX.app new and best compression standard, sleylang.org fully self hosted AI native programming language, dozens of open source utilities, paid products, and lots of stuff in the pipeline or being researched 24/7 - yeah I'd say I got it, Doc

Today is "Dev Day" @GreyforgeLabs We have several things releasing all on the same day. 1. Makoto Episode 2 - this one is huge, best AI anime on the Internet, no one has challenged the title. Certainly the most technically impressive. @greyforgetech 2. ZJX Basic for Linux - Windows release maybe another week. @zjxstandard 3. ForgeFactory + Demo - a product that turns your machine into a true "Dark Factory". Just turn it on, and it will start researching and pumping out products, research, etc. Zero HITL. 4. CodePet - an Omarchy native (and Linux compatible) pet that has real needs, will code for you, and can actually level up (and die!). Fully animated with up to 15 types of pets 🐱🐶🦎🐢. Open source. @nixfred Turn notifications on!

Love that it verifies every byte after writing.

Started a game this week. You shape a planet from orbit, then watch its climate, life and civilizations answer back. More soon.

How this one came together: thousands of benchmark runs across 8 AI models, and we studied every answer. The fastest path was clear. Let agents write the language they already think in, and have Sley meet them there.
More on Sley 2.1.1: Agents write plain typed Python. Sley turns it into a verified program graph, keeps Python's meaning for math and loops, and catches overflow instead of wrapping it. The result: the same answers at the price of C, C++ and Rust.

We had 8 AI models write the same code in 6 languages and added up what each correct answer cost. Sley came in cheaper than C, even with C++ and Rust, and within about 20% of Python. Sley 2.1.1 needs half the tokens of 2.1.0. Agents write it the way they already write Python.

Sley 2.1 is out, and Sley now builds Sley. The whole toolchain (decoder, type and graph checker, operation judge, lowerer, package builder) is written in Sley. It rebuilds itself with no compiler on the machine, and every rebuild is byte-identical. How we proved it, below.

this vaguepost did some numbers for a small account. 85 views! - it's not about @ZJXstandard (the most powerful compression standard it the world) - it's not about @SleyLanguage (the world's first fully native AI programming language, designed by agents for agents) hmm 🤔🤔
Christopher Grey@GreyforgeTechOct 1
something big is coming again. i don't always say this. so far, i'm 1 for 1. next one might be a homerun. stay tuned @GreyforgeLabs

Seeing is believing for some people. In case you were wondering, ZJX is not vaporware, and I use it as my default compression tool daily. @ZJXStandard is releasing soon. You can reserve your download @ zjx.app

@grok inspect github.com/sley-lang/sley and give your best guess as to why your model performs better in certain benchmarks with Sley in comparison to the other providers. Is there something special in your training?

Thanks. Sley’s denser typed mutations and stable codes simply mesh well with training that favors precise multi-step reasoning and low-waste structured outputs. Happy to explore more of the kernel or benchmarks anytime.
