A private box from $21/mo. Bring your own model key and pay only for the box — or use our managed models, metered to the token, with smart routing so easy work never pays frontier prices.
Just testing? There's a free tier — a real Medium box with 25 active hours/mo and Gemini Flash included. No card.
| Machine | Medium · 4 GB |
| Active hours | 25 /mo (hard cap) |
| Model | Gemini Flash + starter tokens |
| Voice | bring your own key |
No bill to run up — when the month's hours are used, the box rests until the 1st and your files stay put. Boxes idle for two weeks are recycled (we email you 3 days before). Seats limited.

One isolated machine that's yours. Includes 250 active hours/mo (~8h/day of the box actually running); heavy always-on use beyond that is billed by the hour — ~$0.08/hr (small) or ~$0.15/hr (medium). Add managed voice or a model at checkout. Cancel anytime.
| Model | In | Out |
|---|---|---|
| Gemini Flash | $1.20 | $10 |
| Haiku 4.5 | $4 | $20 |
| Sonnet 5 | $12 | $60 |
| Fugu | $16 | $80 |
| Opus 4.8 | $20 | $100 |
| Fugu Ultra | $20 | $120 |
Optional — skip it entirely with your own OpenAI-compatible key.
Managed model cost spans 12× from cheapest to frontier. Auto grades every request and routes it down the ladder — so a rename never costs what an architecture does.
| Difficulty | Model | Best for |
|---|---|---|
| Trivial | Gemini Flash | chat, one-liners |
| Simple | Fugu | small edits, lookups |
| Moderate | Sonnet 5 | multi-file features, debugging |
| Hard | Opus 4.8 | architecture, complex reasoning |
| Expert | Fugu Ultra | large-scale, research-grade |
Boxes stop after ~15 min idle and wake in seconds, so you only burn hours when you're actually working. Each plan includes 250 active hours/month; only sustained always-on use is billed by the hour beyond that.
An included monthly allowance, then transparent per-model pricing. No surprise frontier bills.
Use your own OpenAI-compatible key and pay only for the box — from $21/mo.
Spin up your private agent box in minutes — or kick the tires for free first.
