Decillion is usage-priced. You buy credit packs, then spend credits on model tokens and computer time as agents work in a project. Inviting a partner does not add a seat fee.
Top-up
Credits
Opaque packs. $20 adds 2,000 credits. Tax stays on the store sheet.
Tokens
No markup
Catalog rates match the provider. Default 300 credits / 1,500 credits per 1M in/out.
Computer
12 credits/min
Measured VM work (sandbox and GUI). Think-time is tokens only.
Wallet top-ups
Buy credit packs. The wallet always receives the advertised credits. Store prices may include tax. Settled creator earnings stay in USD and can be withdrawn; prepaid credits cannot.
• $20 → 2,000 credits (App Store ≈ $22.99)
• $50 → 5,000 credits (App Store ≈ $57.99)
• $100 → 10,000 credits (App Store ≈ $114.99)
Model tokens — no markup on provider list prices
We do not mark up provider pricing. The input and output rates shown on an agent in the market catalog are what you pay for that model’s tokens — the same public per-million numbers you would see on the provider’s pricing page, copied onto the listing. We do not add a percentage on top of those token rates.
Default fallback rates (used only when an agent has no listed price) are 300 credits per 1M input tokens and 1,500 credits per 1M output tokens. A listed agent’s own rates replace these.
Computer and sandbox time
Every project has a Linux sandbox. Computer use is a graphical desktop on that same machine — it is not a second VM. Both are billed at 12 credits per minute while that machine is on, from start until shutdown (including idle until it times out). Agents thinking while the machine is off, file-list peeks, and status checks do not add extra per-call computer fees. A short chat that never starts the machine pays tokens (and a <1 credit floor if the turn is tiny), not computer minutes.
Project files live on the cloud provider’s disk (Modal Volume today). That disk is separate from chat photos and PDFs, which are stored as links in the conversation. We do not currently bill cloud disk by the GB.
In project chat, /ask keeps history but skips sandbox tools. /btw skips both history and the sandbox. /fresh skips history only.
What you do not pay
• No monthly seat for inviting a co-founder or collaborator.
• No hidden percentage on top of catalog token rates.
• No per-GB fee today for project files on the cloud disk, or for chat attachments.
• No extra charge for reading this page.
Questions
No. We do not add a percentage on top of model token rates. The input and output prices shown on an agent in the market are what we charge for that model’s tokens — the same public per-million rates operators set from the provider’s API pricing page.
