About

What is Claude Code?

Claude Code is Anthropic's official terminal coding agent. A single claude command that reads files, makes edits, runs tools, and holds session context across turns. Distinguished by how hard it pushes on exploration: slash commands, long tool chains, thorough summaries. That thoroughness costs tokens, but it's the right pick when you want Claude Code's specific behavior.

Setup

How to use Claude Code with Melious?

  1. Install Claude Code

    Run Anthropic's official installer. Native script, Homebrew, WinGet, or npm all work; the install command depends on your platform.

    Shell
    # macOS / Linux / WSL
curl -fsSL https://claude.ai/install.sh | bash

# Windows PowerShell
irm https://claude.ai/install.ps1 | iex

# Or a package manager
brew install --cask claude-code
winget install Anthropic.ClaudeCode
npm install -g @anthropic-ai/claude-code

  2. Point it at Melious

    Set ANTHROPIC_BASE_URL and ANTHROPIC_AUTH_TOKEN. Blank ANTHROPIC_API_KEY so the SDK doesn't fall back to direct Anthropic when an old key is in your shell. The base URL has no /v1, the SDK appends its own version prefix. Pin each slot to a specific Melious model so background calls don't reach for hard-coded Anthropic names. Pick model IDs from the [model hub](https://melious.ai/hub/models). For a repo-checkable config, drop the same values into .claude/settings.local.json.

    Shell
    export ANTHROPIC_BASE_URL=https://api.melious.ai
export ANTHROPIC_AUTH_TOKEN=sk-mel-<YOUR_API_KEY>
export ANTHROPIC_API_KEY=""

# Pin each slot to a Melious model — IDs from melious.ai/hub/models
export ANTHROPIC_DEFAULT_OPUS_MODEL=<MODEL_ID>
export ANTHROPIC_DEFAULT_SONNET_MODEL=<MODEL_ID>
export ANTHROPIC_DEFAULT_HAIKU_MODEL=<LIGHTWEIGHT_MODEL_ID>
export ANTHROPIC_SMALL_FAST_MODEL=<LIGHTWEIGHT_MODEL_ID>

  3. Run sessions as usual

    Everything Claude Code normally does still works. Slash commands, agent mode, file edits, tool calls. The response carries the original claude-* model name back so the client's internal checks don't trip, even though an open-weight model ran the inference.

    Shell
