Installing a pack by hand

Unzip the archive so that pack.json sits at the top of the version folder, then restart the app — it finds packs by scanning this directory, so nothing else is needed:

%LOCALAPPDATA%\com.openalchemy.engine-worker\runtimes\<pack_id>\<version>\

Check the file against the sha256 above before unzipping if the download was interrupted.

What's new in this release

Full release notes →
  • Every worker gets a name

    Workers still called "my worker" get a random player-style name like SilentFalcon-worker; rename yours any time or roll a new one with the dice. The Charbit wall now shows the whole cast — 183 pictures of every public character.

  • Charbit™ comes alive in the Grid menu

    The Charbit tab opens with the charbit.ai character wall and shows how many Charbit credits your transferable credits become. Engine Desktop now uses the Grid credits green, and Grid pages fill the window.

  • Send your earned credits to Charbit

    Credits your GPUs earn now settle into your Grid balance every day. Link your Charbit account and send them over from Engine Desktop or Grid.
