Here’s what’s on your invoice

An action is one complete AI-driven step Hydron runs for you, like analyzing your codebase, planning infrastructure, generating a provisioning plan, or executing a deployment. Each one is made up of one or more LLM calls, and credits are deducted at the exact token rates of the model you picked.

Yes, you'll need an active subscription to use Hydron. The subscription includes $20 of credits each billing cycle.

The $20 monthly subscription unlocks the platform, the AI workflow that analyzes, plans, provisions, and deploys for you. It includes $20 of AI credits each cycle, so light usage is covered by the subscription itself. Anything beyond that, extra AI usage or dedicated servers, is billed on top, only when you use it.

Anything AI-powered in Hydron: codebase analysis, infrastructure planning, provisioning plans, deployments, and chat replies. The capacity calculator above shows how many of each action a budget typically covers, based on real platform measurements.

Yes, as long as your subscription is active. Top-ups must be between $5 and $500 per transaction, with no daily or monthly limit on how many top-ups you do. Auto top-up can also refill automatically up to a monthly cap you set.

Hydron provisions dedicated servers from OVH, one of the world's largest hosting providers. The catalog spans budget through enterprise tiers, plus specialty gaming and GPU-accelerated servers for AI/ML workloads. You see the exact price before you commit, with no Hydron markup.

Each dedicated server has a flat monthly fee shown up front, so you know the cost before you provision. You pay through Hydron in one bill — there's no separate hosting account or provider invoice to manage. Servers are billed monthly while they exist; release one any time to stop its charge.

Yes. You can pick any supported model per project — Sonnet as an everyday default, Haiku for fast iterations, or Kimi K3 for an open-weight alternative. Opus and Fable models are available with an active subscription. Switching models is instant and only affects future calls.

It depends on the credit type. Top-ups expire after 60 days and stay in your account even if you cancel your subscription. The monthly subscription resets each billing cycle, so unused credits don't carry over into the next month.

Yes, any time, with no penalty. You keep platform access through the end of the current billing period.

Cancelling keeps your platform access through the end of the billing period. Dedicated servers are billed separately and run as long as you keep paying for them, so releasing a server, or letting its billing lapse, takes the apps on it offline at the end of the paid period, since that's where they run. Everything runs on standard Docker, so you can export the setup and redeploy your stack elsewhere without rebuilding it.
