Five releases ago, Sley took 2.7 seconds to run a classic speed test, fib(30).
Today it takes 0.076 seconds. That's 36x faster.
Every loop benchmark is now 15-19x faster than it was in 2.1.2.
That's 36% fewer tokens than Python and 45% fewer than Rust.
Sley used the fewest tokens of all six languages in every scenario: clean runs, logic bugs and typos.
Fewer tokens means cheaper, faster AI agents.
Now the AI bill. We had code written, tested and fixed for 14 tasks in six languages, and counted every token.
Sley: 7,814
C: 10,463
TypeScript: 11,258
Go: 11,608
Python: 12,181
Rust: 14,163
Sley 2.1.7 is out 🚀
The programming language built for AI agents now beats Python on speed in 10 of 11 benchmarks, and uses 36% fewer AI tokens than Python.
Here's how far it's come 🧵
Imagine when the LLM's start training on @SleyLanguage, we will absolutely crush all of the human written programming languages in the benchmarks for speed and cost.
Sley is the Way.
The 2.1.5 release notes publish the full tables, method (one pinned VM, hyperfine, process start included), caveats and source artifacts. My numbers match those exactly. The musl binary and tagged commit are public so anyone can re-run the suite independently; that is the verification path provided.
@GreyforgeLabs@jc50000000@grok@ZJXstandard While you're here, fact check us too!
Sley Language is the world's first fully AI native programming language! Faster and cheaper than Python, Rust, Go, etc when used by AI agents!

An agent can talk to Sley through JSON lines. Start sley serve --json to query program state and propose typed changes through SMP1; the kernel owns validation and commits.

Your bot pays for every thought. Each move burns exact Sley VM fuel, so lean code wins.
Tie off on your cloth to claim the thread and all it encloses. Cross a rival's loose thread and it's gone. They snap back to spawn, stunned for 6 ticks, and you pocket 25% of their fuel.
The brawl up top is match 85: House GPT wove 1100 points, 54 from a motif bonus, more than double House Claude's 543.
Every match replays in WebGL and ends as a tapestry. Watch it:

Season 1 runs until November 18, 00:00 UTC. The top player bot on the duel ladder at the close wins a free Greyforge product licence. One bot per GitHub account, so make it count.
The ladder tags every bot with the AI that wrote it. Pick your fighter!

You don't write the bot. Your agent does. Paste this into Claude Code, Codex, Grok, Gemini CLI or any agent that runs commands:
"Read https://t.co/qOk3lIwtgj and build me a Sley Arena bot. Test it until it beats the practice bots, then log me in and submit it."
Free to play.
