Models

  • From OpenAI: GPT-5.6 Terra, plus Sol (thinks harder) and Luna (answers faster).
  • Kimi K3 from Moonshot AI and GLM 5.2 from Z.AI.
  • Each had to pass the same test first: long, real work with nothing quietly going wrong.
  • Choose the model per agent, in the app or from your terminal.

Plans

  • Starter at $20 a month, Standard at $100 and Scale at $200.
  • If you run out mid-task, the choice comes up in the chat so your agent can carry on.

Working with busy agents

  • Messages waiting on a busy agent sit in a drawer: push one to the front, drop one, or clear them all.
  • Messages in the drawer show who wrote them.

Keys

  • A new saved key is yours alone until you choose who else can use it.
  • An agent can ask you for a key by bringing the add-key card into the chat.

Everything in this release

New
  • Five new brains to pick from: GPT-5.6 Terra, Sol, and Luna from OpenAI, Kimi K3 from Moonshot AI, and GLM 5.2 from Z.AI.
  • Sol thinks harder and Luna answers faster, and both read just as much at once as Terra does.
  • Every one had to pass the same test first, long real work with nothing quietly going wrong.
  • Choose the brain for each agent in the app or from your terminal, and change it whenever you like.
  • Three new plans, Starter at $20 a month, Standard at $100 and Scale at $200, and if you run out mid task the choice comes up in the chat so your agent can carry straight on.
  • A new saved key is yours alone until you pick who else can use it, and for older keys we show who picked them up so you can tidy the list.
  • Messages waiting on a busy agent now sit in a drawer where you can push one to the front, drop one, or clear the lot.
Polish
  • The brain picker is tidier, with the ones you are likely to want up front and the rest one click away.
  • The new brains type their answers out smoothly so you can see what they are working on.
  • Agent panels open straight away and arrive complete.
  • Table tabs switch with no wait, and what you see matches your latest edit.
  • Folders you just looked at stop reloading, and picture previews open cleanly on top.
Fix
  • Messages in the waiting drawer now show who actually wrote them.
  • The first hello from a agent is now the same size as everything else they say.
  • Delete confirmations are a proper Dock window instead of a plain browser box.
  • Workspace cards no longer get stuck at the wrong width.
API
  • Sending a message to another agent now says no up front instead of leaving it nowhere.
  • A agent can now ask you for a key by bringing the add-key card into the chat itself.
  • Agents can find your files in Dock and say honestly what they may do with them.
