Claude Code VS Code

The Claude Code VS Code extension can also be configured to use TensorX models.

This guide covers the VS Code extension. For the terminal CLI, see Claude Code CLI.

Installation

1. Open VS Code Extensions (Ctrl+Shift+X / Cmd+Shift+X)
2. Search for "Claude Code"
3. Click Install

Configuration

Open VS Code settings (Cmd/Ctrl + ,) and search for "Claude Code". Click "Edit in settings.json" and add:

{
  "claudeCode.environmentVariables": [
    {
      "name": "ANTHROPIC_BASE_URL",
      "value": "https://api.tensorx.ai"
    },
    {
      "name": "ANTHROPIC_AUTH_TOKEN",
      "value": "<YOUR_TENSORX_API_KEY>"
    },
    {
      "name": "ANTHROPIC_MODEL",
      "value": "z-ai/glm-5.1"
    },
    {
      "name": "ANTHROPIC_SMALL_FAST_MODEL",
      "value": "z-ai/glm-5.1"
    },
    {
      "name": "ANTHROPIC_DEFAULT_HAIKU_MODEL",
      "value": "z-ai/glm-5.1"
    },
    {
      "name": "ANTHROPIC_DEFAULT_SONNET_MODEL",
      "value": "z-ai/glm-5.1"
    },
    {
      "name": "ANTHROPIC_DEFAULT_OPUS_MODEL",
      "value": "z-ai/glm-5.1"
    },
    {
      "name": "API_TIMEOUT_MS",
      "value": "3000000"
    },
    {
      "name": "CLAUDE_CODE_DISABLE_NONESSENTIAL_TRAFFIC",
      "value": "1"
    }
  ]
}

Important: You must set ALL model variables (ANTHROPIC_MODEL, ANTHROPIC_SMALL_FAST_MODEL, ANTHROPIC_DEFAULT_HAIKU_MODEL, ANTHROPIC_DEFAULT_SONNET_MODEL, ANTHROPIC_DEFAULT_OPUS_MODEL). Missing any will cause Claude Code to try calling Anthropic models directly, resulting in errors.

Available Models

Model	Value	Best For
GLM-5.1 ⭐	z-ai/glm-5.1	Coding, reasoning, general use
MiniMax-M2.5	minimax/minimax-m2.5	Reasoning, functions
Kimi-K2.5	moonshotai/kimi-k2.5	Vision, functions, long context
MiniMax-M2	minimax/minimax-m2	Coding, fast responses

Switching Models

To switch models, update all model values in your VS Code settings.json:

1. Replace z-ai/glm-5.1 with your chosen model ID in all five places
2. Restart VS Code or reload the window

One-Time OAuth

Like the CLI, the VS Code extension requires a one-time Anthropic OAuth for interactive features. A free Anthropic account works - you won't be charged by Anthropic as all requests route through TensorX.
