After co-inventing ChatGPT, I kept asking myself: why have superhuman chat models not led to AGI? I’ve spent the last 2 years in stealth building a new way to train models (RLCD), and a new type of frontier AI model that we are releasing today: Jev • 20-200x faster • 40-400x cheaper (w/ output tokens free) • Frontier composable intelligence optimized for decisions AFAICT the shortest path to AI-based economic revolution

If you liked the idea of Jev (ultra-fast, typed decision models instead of heavy 70B LLMs), meet Laya—the open-source equivalent. Why it matters for production pipelines: 1. Blazing Speed (<100ms): Avoids slow token-by-token generation. Evaluates options in parallel to make routing/classification decisions in milliseconds. 2. 100% Self-Hostable: Run it locally on cheap hardware (even CPUs). Zero API costs and zero data leaving your servers. 3. Native Typed Outputs: Outputs structured probability distributions directly. No messy regex or JSON cleanup needed. Top Use Cases: • Fast Model Router: Route 80% of easy queries to small models and save frontier LLMs for hard tasks. • RAG Filter: Score and prune retrieved chunks in 40ms before generation. • Real-Time Guardrails: Catch prompt injections before they reach your main agent. The future of AI architecture: Local open-source models handle the fast plumbing. Frontier models handle the deep thinking.

Most people slap the word “AI” on any Buy / Sell button and leave it there. Jev is a model that came out this week to make fast choices. You give it a situation, and it answers with a decision and a probability: buy, sell, or wait. That takes about 200 milliseconds. It is not a model trained by the Qubic network. It is a tool you call, like an API. X is full of people who wired it to a ticker. Some taped it onto Hyperliquid over a weekend. A few have already posted their losses. That shows what it is: a call returned very fast, then the bot keeps going on its own. So the real subject is not “AI can trade.” It is not mixing two things that do not have the same job. Jev gives an opinion and stops there. It does not stay attached to the error. If the trade is wrong the next day, Jev is not the one carrying the score. The account of whoever plugged in the bot is. BPP-9000 is not built that way. Qubic miners train a small network on a year of Bitcoin hourly candles. The network has to say whether the next hour is more likely to go up, go down, or stay uncertain. Errors are counted. More errors means a worse score. Ant Colony keeps the version that misses less than the last one. That work stays on the network. You can still open a page later and reread the result. The difference fits in two sentences. Jev is a judgment you ask for the length of one call. BPP-9000 is a model the network has to carry for a full epoch. I am not running my bag through a bot someone stood up on a weekend. I am waiting for a public score I can refresh. The question I keep: the day both put up an arrow, which one can you still reread the next morning?
