EP 631 : ChatGPT Co‑Creator Debuts TypeSafe Jev, Salesforce Koa, Google Gemini 3.8 Live

What if an AI could make split‑second judgment calls inside your software without ever hallucinating? In today’s episode we break down Diogo Almeida’s newest creation – TypeSafe’s Jev – a “frontier‑intelligence function call” that only selects from pre‑defined options, delivers answers with confidence scores, and does it for $42 per billion input tokens with free output. Developers can call Jev via simple API endpoints, treating it like a high‑speed, hallucination‑free lookup table. That translates to responses in 70‑500 ms, up to 200× faster and 238× cheaper than Claude Fable 5.1, making it a potential default engine for sorting requests, scoring records, or even screening other AIs for jailbreak attempts.Next, Salesforce’s AI lab rolls out Koa, a reasoning model built on Nvidia’s Nemotron 3 Super. Trained on a fully synthetic dataset that mimics irate callers and deal‑closing reps, Koa cuts errors by three‑fold on Salesforce’s internal CRM benchmark and runs entirely inside Salesforce’s own infrastructure, keeping customer data private. Because Koa never leaves Salesforce’s cloud, it also sidesteps latency and compliance headaches that plague third‑party APIs. The company also launches AIforce and a beta of ClaudeForce for customers who still want external models.We also hear from Google, which just unveiled Gemini 3.8 Live – a voice‑first model that can keep talking while it thinks. The Gemini 3.8 Live rollout also introduces an “Extended Thinking” mode that improves coherence on long monologues. Plus a quick look at Odyssey 3’s new world model, Meta One’s paid AI tier, and a surprising “last AI built by humans” paper from Chinese researchers that maps five levels of recursive self‑improvement.Stay ahead of the curve: listen now, share this episode with fellow builders, and subscribe for your daily AI briefing.Tools mentioned: Jev (TypeSafe), Koa (Salesforce), Gemini 3.8 Live (Google), StepAudio 3, siift, Proofrr, Sum Buddy.
