About
We run open models. You run agents.
Voidstone is an inference platform for coding agents. We serve frontier open-weight models and sell the capacity as flat monthly plans, priced in lanes instead of tokens.
Pre-launch. Accounts are open; the API and checkout open soon.
01
Open models
Frontier open-weight models from Moonshot AI, Z.ai, Xiaomi, DeepSeek and OpenAI. New ones join as we add GPU capacity.
02
Lanes, not tokens
A plan is a number of lanes: how many requests you run at once. What runs through them is never metered.
03
The APIs you already use
OpenAI- and Anthropic-compatible endpoints, so the agent you use today works with a new base URL and key.
Your prompts aren’t kept.
We don’t store your prompts, your code or the model’s responses. A request goes to the model, the answer comes back to you, and that’s the end of it.
We don’t train models either, so nothing you send is used to train one. Our cost is the GPUs that run them, and that’s what a plan pays for.
What we do keep
- Your account
- Your email, your name if you add one, and a hash of your password. Your team and your role in it.
- API keys
- A name, the first few characters and a hash. The full key is shown once, when you create it. When each key was last used.
- Account activity
- Sign-ins, sign-outs and changes to your account or team, with the time and IP address.
- Billing
- Your plan, its status and any extra lanes. Payments go through Stripe; your card details stay with Stripe.
- Messages to us
- What you send through the team contact form: company, team size and your message.
Why flat, and why it holds.
Coding agents made heavy use normal. They read whole repositories, run the tests and try again, all day. Priced per token, that work gets rationed; sold as “unlimited”, it gets capped.
We price what the work costs us instead: GPU time, cut into lanes. A lane can only do as much as the hardware behind it, so the heaviest team on a plan costs us the same as the lightest, and there’s no training run to pay back behind the price.
Run your agents without a meter.
