Jeview: unofficial local visualizer for Jev (TypeSafe) proxies calls via 127.0.0.1:4777, logs to SQLite, maps live
An independent developer published Jeview on GitHub, a local proxy-visualizer for TypeSafe's Jev (System One) that logs every call to SQLite and draws them on a live map. It runs as a gateway between user code and api.typesafe.ai, needs only Node 24+, and has zero dependencies. It is not affiliated with or endorsed by TypeSafe AI.

AI Overview
- Unofficial Jeview gateway sits between code and TypeSafe, forwards each Jev request with your key, logs calls to local SQLite, and draws a live map at 127.0.0.1:4777
- Needs Node 24+, has zero dependencies, launches via ./launch.sh which finds Node on PATH, nvm, or Homebrew
- Two demos route real Jev calls through Jeview: a Pixel Knight side-scroller and a support-inbox triage, each costing about ten cents an hour while running
- Project explicitly states it is independent and not made or endorsed by TypeSafe AI

Show HN: Onesie – An expressive CLI for System One models like Jev
Frodi Karlsson released onesie, an MIT-licensed CLI for using System One models (such as TypeSafe's Jev) in shell pipelines, scripts, and local agentic workflows. It adds caching, batching, deduplication, streaming, multi-question requests, and calibration of classifier thresholds against labelled data. It targets TypeSafe's Jev, Jev via OpenRouter, Berget's System One models, and any Jev-compatible API.

this-that-model-1.0: A typed decision model that decides in 30 ms, for a millionth of a cent
Researchers released this-that-model-1.0, a 2B-parameter typed decision model that reads answers directly from hidden states, outputs one of n declared options plus a thresholdable number, and generates zero tokens. It decides in 30.9 ms on one laptop GPU versus 8758 ms for a frontier API call, and scores 0.941 (Brier 0.042) on a third party's 68-question cohort versus 0.765 (Brier 0.133) for hosted service Jev. It is open-sourced on Hugging Face, targeting software branches that need decisions, not prose.

I open-sourced CasaJev: a Jev agent loop that builds and reuses verified tools
A developer released CasaJev, an Apache-2.0 open-source local harness for TypeSafe's Jev that lets an agent build small tools when none fit a task, then register and reuse them on later tasks. In one example, building a tool took 29.29 s versus 2.07 s to reuse it. It is an early prototype with limited OS validation and the author is seeking contributors and feedback.
