Jev × LIBERO

A fine-grained robot control study loop for LIBERO tasks: Jev layers an intent, a contact or motion family, and one of 27 control inputs, while reversible MuJoCo previews evaluate each candidate before execution.

Highlights

  • 27 inputs cover Cartesian translations, wrist rotations, gripper open/close, and hold.
  • Layered decisions: Jev selects an intent, a contact or motion family, and an input, each choice informing the next.
  • Preview branches run for up to 8 environment steps or 0.4 simulation seconds before a control is executed.
  • Runs against the official API with jev-latest or OpenRouter's typesafe/jev-1.13, the CLI default.
  • Recorded episodes: microwave in 14 decisions and 111 steps, top drawer in 20 and 155, alphabet soup in 40 and 314.

Quickstart

bash
git clone https://github.com/Dimweaker/jev-libero.git
cd jev-libero
pip install -e .
export TYPESAFE_API_KEY="YOUR_API_KEY"
jev-libero run --provider typesafe --task top_drawer --seed 1 \
  --out runs/drawer-s1 --max-decisions 100 --budget-usd 0.10

Watch out

MIT-licensed; requires Python 3.10 or 3.11 plus a LIBERO, robosuite, and MuJoCo environment and a TypeSafe or OpenRouter key, and episodes make paid API calls guarded by --budget-usd.

This is actually insane. This uses @typesafeai Jev model, as a plugin in Claude to review all the un-nesseasary tool calls, and it takes 1s to run! Like, literally, 1 second to take my Claude session from nearly 1M to ... 86K tokens! 😮 Ask your claude to install it and be  Show more

found the perfect use case for @typesafeai Jev: instant compaction in 2026, why is compaction still a summarization prompt? Jev can make it instant by scoring every tool call and dropping what’s irrelevant

We're seeing extraordinary results from @typesafeai. Default mode in 𝚏𝚡 is auto, with a safety reviewer analyzing every command. That reviewer runs on GPT Luna today. Jev is up to 18x faster (p95) *and* more accurate. It's coming to @vercel AI Gateway and likely new default.

We benchmarked fx auto mode (safety) classifier with @typesafeai's Jev. tl;dr: ~5-18x faster and more accurate than 𝚐𝚙𝚝-𝟻.𝟼-𝚕𝚞𝚗𝚊, our current top choice
