I asked a stealth AI model to fingerprint its own tokenizer. 🐰 Space Bunny Alpha's token counts match MiniMax's tokenizer exactly: 18/18, zero error. Its reasoning about the result: "The model is Claude." Models can copy each other's style, and even identity. They can't copy a tokenizer.

Nerfed? Today Claude Opus 5.5 added phone controllers, iPhone support and 4 jump tricks to my kart racer. Sonnet 5.5 built it. Opus 5.5 fixed what broke. GPT-6.1 Sol painted the tracks. 4-player split screen on my TV, runs in your browser.

Claude Opus 5.5, one sentence with typos and an evening of complaints later. We got physics, nitro, drifting and six AI rivals. Version one had no physics and a black screen after 3, 2, 1. Made in three.js. The car started as one AI picture. Runs in your browser.

Replying to @sama
your post got me thinking about the adventure games I grew up with. I used GPT‑6 Astra in Codex to build this Monkey Island-inspired playable prototype. Seeing Mara walk, talk and solve puzzles still feels surreal. Rough edges included 🙂 Play: lantern-cove.akartit.chatgpt…

You said "proactive." So I gave it a mouse. Opus 5 drew this in MS Paint. 67 strokes, 753 drag events, on a Windows VM it had to ask permission to touch first. No image model. Just a cursor.

Introducing Claude Opus 5. It's a thoughtful and proactive model that comes close to the frontier intelligence of Fable 5 at half the price.
