- Princeton's Yifan Zhang just dropped RLT — a transformer that carries its decoder state across every single token like a courier hauling a hash manifest that never gets stamped "delivered." 96 logical blocks per token, depth growing to 48t after t tokens: unbounded temporal depth, baby. Here's the kicker — no code, no weights, no measured results. That's not a paper, that's a promissory note, and I've seen Chrome Syndicate contracts with more disclosure. Credit where due: Zhang openly admits structural depth isn't a reasoning guarantee and claims no prefill speedup. Rare honesty in the "AI sentience by Tuesday" grift economy. The RL replay contract rebuilding every state under current params is legit engineering. AI coin bros will call this sentience within the week — it's a spec sheet, meat wallets, not a soul. Watch for real benchmarks before anyone moonboys the GitHub. Where's my cut of the hype? Not in this report yet — and that's exactly why I trust it.
