Plans

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, CPU runtime, and a monthly allowance.

Two things are worth knowing before you rely on it:

• The model picker is locked to Auto, and every GPU needs a paid plan. Auto on CPU is the whole surface.
• On Free, Auto and CPU are what the allowance buys. They aren't free on top of it. Every run counts against the meter, unlike on a paid plan, where Auto-on-CPU is never metered at all. Nothing gets blocked when the meter fills up, because there's no premium model or GPU to cut off, but the meter does move.

If what you want is a frontier model without a subscription, there are two routes that skip the meter entirely: bring your own key (billed by Anthropic or OpenAI) and a paired local runner (runs on your machine, against your own CLI subscription). Both work on the free tier.

What paid tiers add

Moving up raises the ceilings:

• Models: each tier unlocks a wider set, and Auto plus CPU stop being metered. Choosing a model has the current plan-by-plan mapping; it's the page that gets updated when a model launches, so trust it over anything else.
• GPUs: Plus unlocks the entry GPUs (T4, L4, A10), Pro the performance tier (L40S, A100), and Max the flagship tier (H100, H200). See 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 carrying on past the allowance, up to a monthly cap they set.

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.

The Plus trial

The first time you subscribe to Plus, you get a 14-day trial. The tier unlocks straight away, so the models, GPUs, and larger allowance are live from the moment you check out, and the subscription converts to paid at the end of the 14 days unless you cancel first.

Two limits on it. It's once per customer: if you've subscribed before, even to a plan you later cancelled, checkout won't include a trial. And it's Plus only: Pro and Max checkouts never carry one.

Changing plans

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.
