Jev Social
Local Instagram, TikTok, and LinkedIn research app where Jev makes confidence-gated typed choices over the platform and next socai operation, while deterministic Node code validates each decision and the socai CLI performs read-only browser capture.

Highlights
- Jev chooses the platform and each next read-only socai operation, including which post or profile to open.
- Deterministic Node code validates every choice; unsupported, malformed, and low-confidence decisions do not execute.
- Stores each choice, confidence, command, result summary, and elapsed time for every run.
- The recorded Instagram run produced four source-linked records in 63.969 seconds.
- Login gates, decision failures, and step limits produce partial results rather than a success claim.
Quickstart

MIT-licensed. Needs Node 20+, an OpenRouter key with Jev access, and a current socai CLI; the published timings are individual local observations, not a benchmark.

AI multiple choice, not essay writing
WTF is Jev by @typesafeai? Here’s the tl;dr ELI5: Think AI multiple choice, not AI essay writing. It doesn’t chat. It makes decisions your software can act on: “Spam or not?” “Which tool should this agent use?” “Does this need a human?” The exciting part: roughly 200x faster Show more
Screening agent actions with Jev
Tested TypeSafe’s Jev (no-text, probability-only model) as an AI agent safety monitor. Checking each action first worked well caught most attacks with almost no false blocks, and much faster than Gemini.
@CompleteSkeptic
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
