typesafe-computer-use

A macOS computer-use loop that OCRs the screen, asks Jev for the next action with typed Choices, and clicks, at about $0.0002 per decision without sending screenshots to a frontier model.

Highlights

  • Reads the screen with macOS Vision OCR plus the accessibility tree, then sends one TypeSafe request with up to three Choices to pick the next action.
  • Measured $0.0002 per decision and 0.13-0.38 s model latency, versus $0.032 and 5.2 s for Claude Opus 5 on the same screenshot.
  • Runs up to 100 steps and stops on done or none, confidence below 0.4, two consecutive no-ops, a step limit, or Ctrl-C.
  • Only the main display is captured, and icon-only buttons in terminals, canvases, or Spotify reach neither OCR nor the accessibility tree.

Quickstart

bash
uv run clicker "open the Playground"                 # dry run: one step
uv run clicker "open the Playground" --act           # drives the machine, up to 100 steps

Watch out

MIT-licensed. Needs macOS 14+, Python 3.12+, uv, a TYPESAFE_API_KEY, and Screen Recording plus Accessibility permissions; an ANTHROPIC_API_KEY is optional for free-text typing.

72GitHub stars
A hands-free macOS voice assistant: whisper.cpp transcribes locally in about 100 ms, then one roughly 250 ms Jev request selects a typed action plus arguments, and code executes it against the Mac.

A Hermes skill that calls Jev as a typed tiebreaker: the agent submits a state and a question, and Choice, Score, or Noul answers with probabilities let it act or escalate.

Jev Agent Skill Router
16GitHub stars
An optional routing layer for Hermes Agent, shipped as a Python CLI and library, that sends a request and a public skill catalogue to Jev and returns route, no_skill, or review plus confidence and candidate distributions.

拿 Jev 做搜索重排，我先泼一盆冷水：单独用，它没打赢向量检索 TypeSafe 的 Jev 这阵子很火，一堆项目拿它做重排。我们在 Agent Skills Hub 的 33,047 条目录上认真测了一次，164 条中英文真实查询，9,831 对分级标注，整套只花了 2.6 美元 三个结论 01｜单独重排，约等于没赢 Jev 重排 bge-m3 Show more

有美团、阿里的老哥嘛？ 试试加一路召回、重排（离线、近实时实现），我觉得有奇效 他在文本理解上 跟之前机器学习、llm很不一样 还能自动打标签做特征

This made me rethink where AI actually fits into security engineering. For purely engineering work, forget about ChatGPT or Claude. TypeSafe AI just released Jev, and I think it’s going to change how we build AI into security workflows. Instead of asking an LLM to “investigate Show more

Jev 发布没几天，开源社区已经开始疯狂复刻了🔥 最值得推荐的五个模型： 1、Laya 421M：原生决策模型，支持 Mac 2、Decider-2B：最像 Jev，基于 Qwen3.5 3、NanoJev 0.6B：专门的 Decision Head 4、Reflex：Qwen3.5 + Direct Logits 5、System-One 4B：专门做概率校准 Show more

Jev 刚发布没几天，开源社区就出现了同款🔥 Decider-2B模型，是基于 Qwen3.5-2B 做了特殊调整 它和 Jev 模型是一样的 只做选择 评分和判断 不是文本类的 LLM 模型 但两者还是有几个明显区别： 1、模型 Jev：闭源 System One Model Decider：Qwen3.5-2B，约 1.9B 参数，Apache 2.0 开源 2、价格
