the NEW ChatGPT. is it any good?

Jev is a new type of AI based on System 1 thinking. wtf does that mean? Daniel Kahneman coined this idea of System 1 and System 2 thinking. basically, S1 makes decisions super fast; S2 thinks slowly about a problem. think: difference between reacting after feeling your hand on a stove vs using mental maths to calculate 69 x 43. since the end of 2024, AI models have been getting better (much, much better) at S2 "long and slow" thinking. that left a gap for S1. until Jev. that's what i dive into in episode 3 of Lenny's AI Builders (the LAB) + a bunch of other ai news you probs should know about (such as a big one for Claude!). watch LAB 0003 on YouTube grab the inbox rules + copyable prompt: https://notes.lennoxsaint.com/posts/lab-0003 and let me know if you'll be checking Jev out!

i've got 2 for the price of 1 for you: LAB-0005 and LAB-0006. the headlines for 0005: a big maths claim from OpenAI. a model price fight. Grok 4.7 on a real job. what agents might do to app checkout. and a local image model i want to test. how to use GPT-6 Astra to create brand design assets (spoiler alert: the local image model is wild. it does *anything*. without guardrails - scary stuff if put in the wrong hands) check out episode 0005 here: headlines for 0006: Opus 5.5 drops 1.5 hours...
i gave two AI setups the same four hours i built BuilderBench around work i actually use AI for: writing, editing video, designing pages, making motion graphics, using apps, researching decisions and fixing workflows. the first pilot compared Opus 5.5 with Claude and GPT-6 Sol with Codex. same frozen task pack. four hours of offline work, plus a live founder conversation. Extra High reasoning and Standard speed. i scored the anonymous work, then locked my ratings before revealing the names....
7 ai updates that changed how i build this week: we've entered the token scarcity era use a handoff.md for long-running agent tasks check out CUA (Computer Use Agent) if you use Claude agent portability is the new meta; don't get locked in to one app ... ... ... [this one's a fkn doozy!] i'm not gonna make it that easy for you ;) want the last 3 updates? you know what to do! watch LAB 0004 on YouTube speak soon x Lenny
