Claude Code

Claude Code is Anthropic’s developer toolkit for working on a local codebase from the terminal or inside VS Code. It can chat, edit files, and run commands with your approval. Because Claude Code uses the Anthropic API, you can point it to the ScitiX Model Inference API and use supported ScitiX models in the same workflow. Currently supported models are Qwen/Qwen3.5-397B-A17B, MiniMaxAI/MiniMax-M2.5, MiniMaxAI/MiniMax-M2.7, and kimi-k2.6. For model pricing, see the model catalog. This guide covers both the command-line tool and the VS Code extension.

Configure the CLI

1. Install Claude Code

Install the CLI by following Anthropic’s official instructions.

2. Configure environment variables

Create an API Key on the API Keys page, then set the following environment variables:

export ANTHROPIC_BASE_URL="https://api.scitix.ai/model-api"
export ANTHROPIC_AUTH_TOKEN="<Your API Key>"

To keep them across sessions on macOS or Linux, add these lines to ~/.zshrc or ~/.bashrc and restart the terminal. Keep your API Key secure, and never commit it to Git. Environment variables are recommended. Optionally, set a fast model for lightweight background tasks:

export ANTHROPIC_DEFAULT_HAIKU_MODEL="claude-haiku-4-5-20251001"

The older ANTHROPIC_SMALL_FAST_MODEL variable is deprecated. Use ANTHROPIC_DEFAULT_HAIKU_MODEL instead.

3. Run Claude Code

Run Claude Code from your project directory and pass the model name exactly as it appears on the platform:

claude --model Qwen/Qwen3.5-397B-A17B

Configure the VS Code Extension

1. Install the extension

Open Extensions in VS Code (Ctrl+Shift+X / Cmd+Shift+X), search for claude, and install Claude Code for VS Code by Anthropic.

2. Configure the connection

Create or edit ~/.claude/settings.json, then add the configuration below. Replace <API_KEY> with your ScitiX API Key.

{
  "env": {
    "ANTHROPIC_BASE_URL": "https://api.scitix.ai/model-api",
    "ANTHROPIC_AUTH_TOKEN": "<API_KEY>",
    "ANTHROPIC_DEFAULT_HAIKU_MODEL": "claude-haiku-4-5-20251001",
    "CLAUDE_CODE_ENABLE_TELEMETRY": "0",
    "CLAUDE_CODE_DISABLE_NONESSENTIAL_TRAFFIC": "1",
    "CLAUDE_CODE_ATTRIBUTION_HEADER": "0"
  },
  "prefersReducedMotion": true,
  "model": "Qwen/Qwen3.5-397B-A17B"
}

The fields that connect Claude Code to ScitiX are:

Field	Description
`env.ANTHROPIC_BASE_URL`	ScitiX Model Inference API base URL: `https://api.scitix.ai/model-api`
`env.ANTHROPIC_AUTH_TOKEN`	Your API Key from the API Keys page.
`env.ANTHROPIC_DEFAULT_HAIKU_MODEL`	Optional fast model for lightweight background tasks, such as `claude-haiku-4-5-20251001`. Replaces the deprecated `ANTHROPIC_SMALL_FAST_MODEL`.
`model`	The model to use, such as `Qwen/Qwen3.5-397B-A17B`.

After saving, reload the VS Code window so the settings take effect.
