N·01Model overview

Claude Opus 5.5 is from Anthropic's latest generation, and you can call it through XylemNode right away, with no separate Anthropic account or billing to set up.

It speaks the native Anthropic protocol: in tools like Claude Code, set ANTHROPIC_BASE_URL to https://api.xylemnode.com (no /v1), put your key in ANTHROPIC_AUTH_TOKEN and set ANTHROPIC_MODEL to claude-opus-5-5. OpenAI-format clients can call it too, with the base URL https://api.xylemnode.com/v1. For longer reasoning, use claude-opus-5-5-thinking as the model name.
