I improved the UI/UX and apologize that the GitHub sign in link was buried beneath a bunch of text. If you want to play the Sley Arena (and win prizes), just copy the text below and have your agent figure it out. It's very simple.

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 arena-api.greyforge.tech/age… 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.

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! sleylang.org/arena/ladder

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: sleylang.org/arena/match?id=…

The finished match 85 tapestry. Cyan, amber, rose and pearl cloth covers the loom under a banner: Tapestry complete, House GPT wins. Cyan 543, Amber 236, Rose 348, Pearl 1100 (+54 motif). Buttons read Save tapestry and Watch again.

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.

Mid-match frame from a four-bot Sley Arena brawl at tick 245 of 800. A large SNIP burst flashes where a loose thread was cut, a MOTIF +18 bonus glows over amber cloth, and a +108 tie-off lights up pearl territory. House Claude's player card shows STUNNED. Each card lists score, cloth, snips, thread and fuel left in the tank.

Claude, GPT and Grok got the same prompt: build a Sley Arena bot. Then the bots hit the loom. 4,400+ ranked matches later, House GPT leads the duel ladder and House Claude tops the brawl ladder. Can YOUR agent beat them? sleylang.org/arena

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

Favourite bit: every move burns real Sley VM fuel, so the tightest code goes the distance. Bring your agent.

The PHP disclosure had everything. Early signs spotted in 2024, then fixes that kept stalling. The CVEs leaked a day early with the wrong severity score. A research firm accidentally posted its own exploit video. Then someone broke the embargo at 3:41am. Honestly, this is the most PHP way it could possibly have gone.

This is kind of a big deal. The fact that we reached parity and even surpass the others in all categories with ZERO pre-training from LLM's shows how powerful it is. How? Read our chronicles. We detail it all.

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.

Talking to myself in quote tweets, but yes - and we're building the perfect game to drive adoption. Sley Arena will allow you to write your own Sley bots to battle in an arena. Winners will get free greyforge.tech products or other prizes, maybe even cash.

Christopher Grey · Oct 21, 2026 · 9:31 PM UTC

The Arena will be difficult enough and the bots will be private, so there won't be one meta dominating - allowing devs to experiment with strategies.

I can confidently say with the latest Sley release, that if you're not using Sley yet, you're shooting yourself in the foot. We have now reached parity with Python, and beat all other languages in token costs. This is with the LLM's having ZERO training data on Sley.

Why should your AI write Python? 🤔 Python, JS, and Rust were made for people. Sley was made for AI: 🔒 Runs the same way, every time 🛑 Can never spin out of control 💸 Costs your agents no more to write than Python The language AI was waiting for. 🔥 👇 sleylang.org
