Features

• Shows the active provider and model in the status bar
• Choose OpenAI or Anthropic from the sidebar
• Updates the selected client configs automatically
• Creates a .bak backup before changing any file
• Edit the models list from the extension (Edit models.json)

How to use

1. Open a project folder in VS Code / Cursor
2. Click the PAULOJO AI Workspace icon in the Activity Bar
3. Choose Provider, Model, and Clients
4. Click Apply

You can also use the Command Palette:

• AI Workspace: Switch Model
• AI Workspace: Edit Models

Files updated

Claude Code in VS Code/Cursor does not use ~/.claude/settings.json for the extension model picker. This extension updates keys such as:

• claudeCode.selectedModel
• claudeCode.defaultModel

(configurable via Claude Model Setting Keys)

Custom paths per client

Important: choose Anthropic to update Claude Code. Choosing OpenAI updates Codex only.

Compatibility

Each provider maps to the client that supports it:

Incompatible clients are disabled in the UI so you do not apply the wrong model to the wrong tool.

Models list (models.json)

You do not need to install anything manually.

Click Edit models.json in the sidebar (or run AI Workspace: Edit Models).
The extension creates an editable file at:

~/.ai-workspace-manager/models.json

On Windows that is usually:

C:\Users\<you>\.ai-workspace-manager\models.json

Edit, save, and the list reloads automatically.

Example:

{
  "providers": [
    {
      "id": "openai",
      "name": "OpenAI",
      "clients": ["codex"],
      "models": [
        { "id": "gpt-5.5", "label": "GPT-5.5" },
        { "id": "gpt-5-mini", "label": "GPT-5 Mini" }
      ]
    },
    {
      "id": "anthropic",
      "name": "Anthropic",
      "clients": ["claude"],
      "models": [
        { "id": "claude-sonnet-4.6", "label": "Claude Sonnet 4.6" },
        { "id": "claude-opus", "label": "Claude Opus" }
      ]
    }
  ]
}

Optional: set Models Config Path in Settings to use another absolute path.
