Claude Code

Official docs:

• Claude Code model configuration
• Claude Code LLM gateway configuration
• Claude Code environment variables

Recommended Surface

Use the Anthropic-compatible surface:

Base URL: https://api.sovrun.one/anthropic
Model:    sovereign-alpha

Environment Variables

export ANTHROPIC_BASE_URL="https://api.sovrun.one/anthropic"
export ANTHROPIC_API_KEY="sk-sov-live_..."
export ANTHROPIC_MODEL="sovereign-alpha"

If you want sovereign-alpha to appear in the /model picker as a custom entry, Claude Code supports:

export ANTHROPIC_CUSTOM_MODEL_OPTION="sovereign-alpha"
export ANTHROPIC_CUSTOM_MODEL_OPTION_NAME="Sovereign"
export ANTHROPIC_CUSTOM_MODEL_OPTION_DESCRIPTION="Sovereign stable model"

Notes

• Keep CLAUDE_CODE_ENABLE_GATEWAY_MODEL_DISCOVERY disabled unless you specifically need discovery behavior.
• ANTHROPIC_BASE_URL changes where Claude Code sends requests; it does not change the model automatically.
• Sovereign currently exposes a stable public model name rather than Anthropic-branded model IDs.

Quick Check

Run:

claude --model sovereign-alpha

or inside Claude Code:

/model sovereign-alpha
