Jev plays StarCraft shareware

Highlights

  • Jev completed Strongarm on development attempt 16, and the captured original victory screen was visually reviewed.
  • The verified run recorded 421 model decisions, 424 API attempts, 9,445,640 input tokens, and a 382.95 ms median latency.
  • The game is paused during state reads and inference, and Jev receives structured observations while screenshots are only for viewers.
  • The model was requested as jev-latest and resolved to jev-1.13.0, with 3,867 game frames captured over 17 min 37.88 sec.
  • Runs the 1998 Windows executable inside BottleShip and needs Python 3.11+, Node/npm, Chrome with WebGPU, and FFmpeg.

Quickstart

bash
python3 -m venv .venv
source .venv/bin/activate
pip install -e .
scripts/setup-runtime.sh
scripts/start-runtime.sh
python -m tsai_sc.run --env-file "$HOME/.config/tsai-sc/env" --run-dir runs/my-attempt --max-requests 2000

Watch out

MIT-licensed harness; BottleShip is Apache-2.0 and StarCraft assets are Blizzard's, not included. Tested on macOS Apple Silicon, and the single successful run does not establish a win rate.

The open System One roundup

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

Classifying 1,500 real emails

this model is actually insane at email classification i tested it on 1500 of my own emails to see how well it works and I am blown away

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

Fast browser use with Stagehand

we built blazing fast computer/browser use with Jev + @Stagehanddev. this task cost $0.001 and executed at near instant speed (in a remote browser btw) the loop: observe the page, send a11y tree as state + actions as questions, Jev decides the next action, then Stagehand Show more
