Plans
What the free tier includes, what the paid tiers add, and how to choose.
Clusy has four tiers: Free, Plus, Pro, and Max. This page explains what changes as you move up. For exact prices and current limits, check the Billing section in the app. That's the source of truth, and the numbers there are live.
The free tier
You can do real work for free. The free tier gives you the Auto model (fast, and never metered), CPU runtime (also never metered), and a monthly allowance for the metered extras.
It's genuinely useful, not a teaser. The two things that cost money on any plan, the bigger models and GPU time, are exactly what the free tier limits, while the everyday loop of Auto on CPU stays free. See the free floor for why that combination never touches your balance.
What paid tiers add
Moving up raises the ceilings:
- Models: access to the mid-tier models (DeepSeek V4 Pro, Kimi) and then the frontier ones (Claude Sonnet and Opus). See Choosing a model.
- GPUs: more powerful GPU types in the runtime picker.
- RAM: Free tops out at 8 GB, Plus at 32, Pro at 64, Max at 128.
- Allowance: a larger monthly allowance for metered usage.
- Storage: a larger workspace.
- Pay-as-you-go: paid tiers can opt into overage past the allowance.
How to choose
Don't overthink the tier. Upgrade when you hit a specific wall: you want a frontier model the agent can't reach, you need a GPU that's locked, you've run into the RAM or storage limit, or you're regularly using up your allowance. The wall you hit tells you which tier you need.
- Trying Clusy, or doing CPU-bound analysis? The free tier covers it.
- Want better models and a GPU now and then? A paid tier opens both.
- Training seriously or leaning on the best models daily? The higher tiers raise every limit.

Upgrade, downgrade, or cancel from Settings → Billing. Subscriptions and invoices go through Stripe, and there's a link to the billing portal in that same section.
