Godspeed thinks with the AI account set in Hermes, the program that runs your assistant. Change it there, and the chat and your routines both follow. The notebook's chat shows the new model within five minutes, after you reload the page.

With an API key, in Settings

#
  1. In your notebook, open Settings. Your AI is near the top.
  2. Choose the service, fill in Model and Key, and check that Use it for the daily routines and the chat too is ticked.
  3. Click Test and connect. It sets Hermes as the steps below do, then checks that your routines reach the new AI.

With a ChatGPT plan, in Settings

#
  1. In Settings, under Your AI service, choose ChatGPT (sign in with your ChatGPT plan).
  2. Click Sign in with ChatGPT, open the page it shows, type the code there and sign in.
  3. It says "Connected. Your ChatGPT plan" with the model it found.

On Windows

#

In your notebook, click Settings, then Open the Windows assistant. The Hermes app opens: change it in the app's settings, under Model. Or use PowerShell, which asks step by step:

  1. Press the Windows key, type PowerShell and press Enter.

  2. Paste this line and press Enter:

    PowerShell
    $s = "$env:LOCALAPPDATA\Godspeed Mission Control State"; if (-not (Test-Path "$s\installation.json")) { $s = "$env:LOCALAPPDATA\Godspeed Mission Control Full Alpha State" }
    $a = Get-Content "$s\assistant.json" -Raw | ConvertFrom-Json; $env:HERMES_HOME = $a.home; & $a.executable model

    The first line picks your state folder. A Windows install made before 2.0.0-beta.11 keeps the older name, which ends in "Full Alpha State", also after updating.

  3. Carry on from step 2 of On a Mac or Linux computer. Its lists are numbered: type a number and press Enter.

On a Mac or Linux computer

#
  1. Open a new terminal window and run:

    Terminal
    ~/.local/bin/hermes model
  2. It shows the AI it uses now, then a list of AI services. Choose with the arrow keys and Enter.

    • A ChatGPT plan: choose OpenAI, then ChatGPT or Codex Subscription.
    • An API key: choose the company your key is from.
  3. Sign in:

    • ChatGPT: open https://auth.openai.com/codex/device on any device, type the code it shows and sign in.
    • API key: paste your key when it asks.
  4. Under "Select default model:", choose a model.

  5. You see a line that starts "Default model set to:". Close the window.

On a server

#
  1. In your Telegram chat with Godspeed, send /model --global. (/model alone changes it for this chat only.)
  2. Pick a model from the buttons.

Telegram exists only on a server installed with the one-line command, and its buttons offer the AI services already set up there. On a server without Docker, follow the Mac and Linux steps in its terminal.

For one chat only

#

Under the notebook's message box, Model picks another model and Reasoning effort (with a ChatGPT plan) sets how hard it thinks, until you close the chat.
