Each accepted AI turn in Plan mode costs 1 credit after Mythos saves its response. Editing or saving the draft yourself, approving it, or cancelling it does not spend another Plan credit. The Build after approval is charged separately.
What a credit is
A credit is the unit you spend on an AI action. A new project, an edit, a template remix, or an accepted Plan AI turn has a fixed price. A Plan turn reserves its credit when the turn starts and keeps it only after a durable response is saved. Failed Plan turns and failed Builds are refunded.What actions cost
Packs
You buy credits in one-time packs using USDT on TON, USDT on Solana, or USDC on Solana.
Both packs include a private repository per React + Vite project, the option to connect your GitHub account so Mythos can create a new private repository you own with two-way sync on one selected active branch, and a priority preview queue. Ultra adds direct Telegram support. Credits from any pack never expire.
Buy credits
1
Open the pricing page
Go to Pricing from your dashboard or the credits menu.
2
Pick a pack and rail
Choose Pro or Ultra, then select USDT on TON, USDT on Solana, or USDC on Solana.
3
Use the universal invoice
The invoice shows the network, token, receive address, exact unique amount, and a QR/payment link. It works for a compatible wallet or exchange withdrawal.
4
Send the exact amount
Pay sender-side network or withdrawal fees separately so the full amount arrives. For USDT on TON, use the receive address shown by Mythos and do not add a memo or comment. Solana payment links include the invoice reference.
5
Wait for on-chain confirmation
Once the selected network confirms the transfer, the credits land in your balance automatically.
Mythos uses direct on-chain checkout. There is no separate wallet or exchange mode and no card subscription to cancel; choose a supported rail and follow the same invoice.
If an AI action fails, you are not charged
Each Plan AI turn or Build settles against a durable result. A failed Plan turn releases its one-credit reservation, and a failed Build refunds its Build charge.Referrals
