Buy AI compute

You can buy real AI compute, and live chain data, with an account's dollars. Four AI models that run on the 0G Compute Network are sold through Nuntio's commerce gateway, and on Monad mainnet so is live Monad data, which the gateway buys over x402. A run is paid in AUSD on Monad like any other payment, so the spender's allowance, payment cap, approved services and the account's pause all still apply.

On Monad mainnet these are the only things to buy today: there are no outside merchants yet. The first mainnet purchase was made on 15 October 2026, $0.01 for one 0G Chat answer, paid from Nuntio's own account at block 113,711,699.

#The four AI models

All four are the cheapest of their kind on 0G mainnet, and all four are sold by 0G providers that run in a trusted execution environment (TEE). Chat, voice and image run inside the enclave, and it signs the result you get. Video runs on ByteDance's model: the enclave signs that it passed the job to ByteDance and the job's final status, and the clip itself is not signed.

Voice is speech to text. 0G offers no text to speech on mainnet today.

The price of each run is set when the gateway quotes it, from what the run can cost on 0G, and is never less than one cent. You see the exact price before you pay.

These replaced the demo services that stood in for AI before 15 October 2026 (Corvane AI, Scribewell and Foldline Studio). Those, and the other demo services, are retired: see Merchants.

#Monad data over x402

On Monad mainnet the Compute page also sells Monad block: one fixed query for the latest Monad block number, read from Ankr's paid RPC.

• Your account pays Nuntio's gateway in AUSD, under the same policy as any other run.
• The gateway pays Ankr in USDC over x402, from its own wallet, up to 0.001 USDC a query. The run shows that payment's transaction on the Monad explorer.
• The data has no TEE attestation. The USDC payment shows the gateway paid for the query; it does not prove what the answer says.
• The query is fixed. You cannot choose the method, the address it is sent to, or who is paid.
• It is sold on mainnet only, and you opt in to it: Nuntio does not add it to an owner's default policy. Allow it with Allow on my policy on the Compute page, or on a spender's page.

#How a run works

1. 1

   #The price is locked

   The gateway quotes a fixed price in AUSD and signs it. The quote is valid for two minutes.

2. 2

   #Your account pays

   The run is paid with an ordinary payment from the account. The contract checks the spender's policy as it does for every payment. The payment carries a key made from the quote, so one quote can be paid at most once.

3. 3

   #The model runs on 0G

   The gateway sees the payment on Monad, runs the model on 0G and pays 0G for the work from its own 0G balance. It checks the provider's signature on the answer before accepting it.

4. 4

   #The result is kept

   The answer is kept with the purchase for 30 days. Fetching it again never pays again.

#In the app

• The Compute page lists the four AI models, and on mainnet Monad block, with their price per run. Running a model opens a panel that shows the price, the payment, the run on 0G and the signature check, then the answer. A Monad block run shows the gateway's USDC payment to Ankr in place of the signature check.
• Activity shows each run with its payment and its result tracked separately, so a paid run that is still working never reads as failed.
• A spender can buy a run only when its service is approved on their policy. When Nuntio first adds an owner as a spender of their own account, it approves the four AI models, not Monad block. An owner approves any of them for anyone else on that spender's page, under Change this policy.
• Agents cannot buy compute yet. An agent's policy can approve these services, and its page shows which, but there is no way yet for an agent to buy a run on its own.

#Who is selling

The seller is Nuntio's commerce gateway, labelled "run by Nuntio". The work is done by independent providers on the 0G network. The gateway pays them in 0G on 0G's own chain; the account's dollars stay on Monad and go only to the gateway's registered payee. There is no bridge in the path of a run.

#If something goes wrong

• The model fails after you pay. The gateway tries another provider of the same model if there is one. If the run still cannot finish, the AUSD is owed back to the account and the Nuntio team sends it back.
• The payment lands after the quote expired. The run is still delivered at the price paid.
• The answer takes a long time. Ask for it again by its purchase ID. A slow answer never triggers a second payment.

#Limits

• The contract does not enforce the quote's terms. The gateway honours them as the merchant.
• The seller is Nuntio, not an independent merchant.
• Each model has one provider on 0G today, so a provider outage means a refund rather than a retry.
• 0G's prices are set in its own token. The gateway prices each run in dollars when it quotes, and the quote holds for two minutes.
