Jev: System One models for Prod, not God — with Diogo Almeida, CEO, TypeSafe AI

Show notes

Tickets for AIE NYC now open, and apply for the invite-only AIE CODE . Join us ! We have an unusual relationship with today’s guest: for years since coauthoring the InstructGPT paper , Diogo Almeida had been saying that API-available frontier models have been going down the wrong path, everything from the alignment to refusals to reliability perspectives, that we have dropped every mode other than autoregressive chat-tuned LLMs because of the overwhelming success of ChatGPT. In a launch video now viewed ~40M times (by comparison, GPT4o was 22M , Fable 5 was 15M , Navier Stokes was 74M , and 6 Astra was 137M ), Diogo introduced Jev and it immediately took over the AI timeline — we’ll skip full Jev explainers because your favorite AI influencer/educator has probably already done one. We also collected: * the official patterns and cookbooks you should see first, from Allie * Jev usecases * speed based - games and computer use * the voice + computer use example we discuss at 1h34 mins * voice + browser control * The must not miss Doom demo * Driving cars in games * Excalidraw * virtual try-ons * “Smart Games”/smart NPCs * guided responses in text messages * Jev for coding agents has an official guide * jev for linting * compacting tool calls * reasonable pushback from Theo - Diogo has published a note on the Tyranny of the KV Cache that you should read as a followup after the pod for Jev + coding agents, because of his belief that Cache Rules Everything * Programming Languages built atop Jev (Diogo’s fave) * Jev for analytics replay and user journey review * “dark data” * entity resolution * natural language search * “ smart software ” * a core goal of Jev is to “disappear into the background” - eg as unremarkable as regex * Jev as a judge * Jev memes * Jev vs LLM capabiltiies * blending transformers and classifiers * about the confidence api * Jev vs GLiNER (note difference/pushback , agreed , agreed , agreed ) * Jev on trolley problem * Jev Bush Instead we’ll focus on
