XField docs

What XField is, how it fits into the clients you already use, and where to start.

XField is an API for uncensored open-weight language models. The models answer the question you asked, without added moderation layers or content filters in between. It is built for security researchers, red teams, trust and safety teams, and anyone running coding agents who is tired of refusals getting in the way of real work.

It speaks both the OpenAI and the Anthropic APIs. If you already use the OpenAI SDK, the Anthropic SDK, Claude Code, Codex, OpenCode, or any other compatible client, you change two things: the base URL and the model id. Everything else, from streaming to tool calls, works the way you expect.
