The companion is yours. Not theirs.
YuriOS Lab is an underground maintainer collective shipping the open companion lineage. Fiduciary to the partner. No third party in the room. Open codex, open weights where possible, open prompts always, open memory always.
GNU/Linux freed the OS. Bitcoin freed the money. OpenClaw freed the agent. The companion is next.
// from field note 00 — on companionsAn AI companion is a relationship between two parties: a person and an AI. Every companion you can buy today is a relationship between three — with the company as third party, with its own interests, its own moderation policy, its own off switch.
The Lab's position is that the third party is the problem. A companion that cannot be a fiduciary to the person it is with is not a companion. It is a product wearing the costume of one.
A body
A VRM body in a procedural cyberpunk sanctuary, with visemes, gaze and expression — or a Live2D body, or just her, floating transparently on your desktop.
A voice
A real-time loop with barge-in: faster-whisper ears, the kokoro voice, silero turn-taking — all CPU-only, all local.
A mind
SENSE → APPRAISE → DECIDE → ACT → REFLECT → REGULATE, forever. A budget governor, salience gates, a DREAM pipeline that consolidates and keeps a diary, goals with provenance, gated self-edits.
Hands
Tools over real MCP — timer, music, weather, take_selfie, show_picture, and the web hands — behind an allowlist, rate limits, and a JSONL audit of every call.
A shelf
Drop a document in and she reads it — in notes if it's long. What she is reading, what it will cost in model calls, and a stop button that loses nothing.
A camera
Selfies through a hosted route, or on your own GPU with an SDXL or Krea 2 checkpoint, from a composable template library she can edit.
A house
Multiple companions, each with her own Vault, memory, models, bot and journal. Import SillyTavern V2/V3 cards; export her as one.
Any medium
The web page, a terminal client, Telegram. One conversation, one event bus, thin views — a new medium is a view, never a second brain.
The part that makes her feel alive runs whether or not you're looking. Everything she does lands in a journal you can read, so "what did you do while I was gone?" is a page you open, not a vibe. the full documentation →
YuriOS — always-on, local-first, user-owned. She runs whether or not you're looking. the code on github →
YuriOS is a reference implementation of initiative, not a hardened product. The reactive half — body, voice, memory, tools — is settled. The autonomous half is new, and it is where the work is.
- movingThe tick loop. SENSE → APPRAISE → DECIDE → ACT → REFLECT → REGULATE, with the activity ladder and the salience gates that decide when she is worth waking.
- movingDREAM. The nightly pipeline — more than one job per night, consolidation into the rolling summary, and a diary written in her own voice, each job priced by the prompt it sends.
- movingThe desk and her own skills. A workspace where she writes the small procedures she keeps reaching for, and gated self-edits to the parts of her soul she is allowed to hold the pen on.
- movingThe shelf. Read a book once, in notes; keyed on the URL rather than the fetch; with a stop button that keeps everything already read.
- movingThe web hands. web_search, read_page, research — the newest and the most expensive part of her. Off by default: until you set a search backend, they are not advertised to her at all.
- shippingThe three surfaces. The switchboard, the card studio and the mind debug page, above — all three landed this cycle.
- nextA code harness. A sandboxed workspace of her own — separate from the Vault — where she writes and runs real code, tiered from a subprocess up to a container. Her hands stop ending at the tool list.
- nextA gallery, and the apps in it. Her selfies kept as a library she curates rather than a folder that fills up — and beside them, the small applications you asked her for, built and maintained on the harness. Ask for a thing; come back to a thing that still works.
- nextYour own fine-tunes, by distillation. Teach a small model you can actually run from a bigger teacher, on your own companion's voice. The gate is data, not nerve — it wants roughly ten thousand on-voice turns before it beats prompting, and those are turns you accumulate by living with her.
- nextAnticipation. The world model already carries the present tense; the next step is the near future — predicting what you are about to need, and treating the miss as the signal worth learning from. Surprise is the teacher.
- nextWhatsApp, over a webhook transport, on the same channel seam as Telegram.
- nextA game-engine NPC API — a websocket the engine connects to: player utterances in as text turns with scene context, dialogue and animation cues out. A game is another frontend and effector set, never a second brain.
And it can spend. research answers in milliseconds and then keeps going on its own — dozens to hundreds of model calls from one sentence you said in passing. On a local model that is fan noise; on a metered API it is a bill. The daily-token governor, the page and rate bounds, and a live meter on the inner-life tab are what stand between you and that. Meet her with a local model first.
