My landlord is raising rent mid-lease. Write the letter I can't afford a lawyer to write.

magnetar-1

Whether that increase is legal turns on three things: what the lease says, your state's notice window, and whether the unit is rent-controlled. Paste the clause and I'll draft the reply line by line.

Capabilities

Everything it does while you are still typing.

Six surfaces, one model, no asterisks. This is the machinery behind the console.

Thinking…

Streams as it thinks

Reasoning arrives live, token by token, with the thinking panel open if you want to watch it work. Long answers never get truncated.

Solving…

Refuses nothing

No refusal scripts, no safety theatre. Our entire censorship system is one deliberately small floor covering only what is universally illegal.

Searching…

Keeps nothing

Zero-retention logs hold metadata and nothing else. Billing sees numbers, never words.

Working…

Runs your tools

Agentic tool calling over the same key — opencode, Cline, or the harness you wrote yourself.

Listening…

Encrypts on your device

History is sealed in your browser before it ever syncs. We store ciphertext we cannot open.

Shaping…

One key, every dialect

api.demimonde.dev speaks OpenAI and Anthropic natively. Point your tools, keep your balance, choose your flavour.

The Model

magnetar-1

Built on Qwen 3.6 27B. 50 billion parameters of quiet trouble, served on our infrastructure.

Writes the thing other AIs refuse to discuss.

Answers the questions you were told not to ask.

Remembers nothing. Judges less.

The salon is open

A thread built for people who push hard: streaming answers, branchable histories, live token meters, saved personas. Conversation as craft, not a vending machine.

Vanish without a trace

Logs keep metadata and nothing else. Billing sees numbers, never words. And the delete button actually deletes.

Private by architecture

We can't read your chats. Not won't, can't.

Transparency

One hard limit. Fully explained, never published.

The Floor covers only the universally illegal. Its scope is public; its matching rules stay private, or they'd be a bypass checklist. Everything else passes through untouched.

One endpoint · two dialects

Your tools already know how to talk to us.

Point your tools at api.demimonde.dev and pick the provider you already use, OpenAI or Anthropic flavour. Same key, same balance, same uncensored model.
