What X6 is

X6 is a chat and agent workspace that runs on your own computer. It uses the EdStratum Labs x6 model through a standard chat completions API and adds what a plain chat page lacks: tools, a plan, approvals, file handling, and checks on its own work.

What it does

Section titled “What it does”

Researches

Searches the web, reads pages, and cites what it found.

Builds

Writes code and pages in a workspace folder, runs them, and checks them in a headless browser.

Works with files

Reads, writes, and previews files. It also produces Word, PDF, and other documents.

Delegates

Splits large tasks into sub-tasks that run in parallel, each with its own tools and summary.

How it is put together

Section titled “How it is put together”
  • One server, one page. A Python server (standard library only) serves a single HTML page with no build step. The server holds the API keys; the browser never sees them.
  • Runs live on the server. When you send a message, the server starts an agent run. It streams replies, calls tools, and waits for approvals. Closing or reloading the page doesn’t stop it.
  • Chats are stored on the server, so every paired device sees the same conversations.
  • The model’s default instructions are kept. By default X6 sends no system message, so the model’s own deployment instructions apply; its safety behavior depends on them.
