A charge labeled “01 AI Pte Ltd” on your card or bank statement is a payment to 01.AI, an artificial intelligence company that bills through its Singapore-registered entity. The charge almost always comes from use of the company’s developer API platform, which bills based on how many tokens its AI models process rather than on a flat monthly fee.101.AI. API Platform Documentation The “Pte Ltd” tag is simply the Singapore corporate suffix the company uses for international billing.
Why the Amount and Timing Look Odd
01.AI’s platform charges per use. Different models carry different prices: the yi-large model runs $3.00 per million tokens for both input and output, while yi-large-turbo and yi-vision each cost $0.19 per million tokens. Spending unlocks higher tiers, up to Tier 5, which allows up to $2,000 in spending after $1,000 in cumulative payments.101.AI. API Platform Documentation
Because billing follows actual consumption, charges can appear at irregular intervals and in irregular amounts. If you (or a developer working on something for you) signed up for API access and generated activity, that is the likely source.
How to Stop Future Charges
The fastest way to stop additional billing without closing the account is to log into the 01.AI platform, remove your saved payment method, and revoke any active API keys. With no valid key, no further tokens can be consumed on your account.
To close the account entirely, email yi@01.ai with your account number and complete the SMS verification the company requires. 01.AI says it will process cancellation requests within 15 working days after verification.201.AI. User Service Agreement You remain responsible for any charges incurred before cancellation takes effect.
Getting a Refund From 01.AI
01.AI’s user agreement sets a general no-refund policy. Once payment is completed, the company will not refund unless the paid service is unusable because of an infringement dispute caused by the company itself. Refund requests go to the same support address, yi@01.ai.201.AI. User Service Agreement If your situation does not fit that narrow carve-out, the merchant route is unlikely to produce a refund, and the bank route becomes the realistic option.
Disputing the Charge With Your Bank
If the charge is genuinely unauthorized, or if 01.AI will not resolve it, you can dispute it through your card issuer. Under the federal Fair Credit Billing Act, send a written dispute to your issuer’s billing inquiry address within 60 days of the statement date on which the charge first appeared. Include your name, account number, the reason you believe the charge is an error, and copies of any supporting documents. The issuer must acknowledge the dispute within 30 days and resolve it within 90 days.3Federal Trade Commission. Using Credit Cards and Disputing Charges
Your liability for unauthorized credit card charges is capped at $50 by federal law.3Federal Trade Commission. Using Credit Cards and Disputing Charges While the investigation is open, you can withhold payment on the disputed amount, and the issuer cannot report you delinquent or send that amount to collections.
Most banks also accept disputes through their website or mobile app. Visa and Mastercard network rules generally give you 90 to 120 days to initiate a chargeback.4Competition and Consumer Protection Commission. Disputed Card Transactions and Chargeback Issuers typically ask whether you tried the merchant first, so a short email to yi@01.ai documenting the attempt can help your case even when you expect it to go nowhere.
