❗️Anthropic accidentally billed a free user… $16.6 million Imagine opening your email and seeing a $16.6 million invoice from Anthropic despite being on the free plan and never using the API. That’s exactly what happened to a user in South Korea. Even stranger, the day before, the invoice was $1.67 million, meaning the amount increased 10× overnight. At first, the user assumed it was a phishing scam, but the email and payment link both came from Anthropic’s official domain. The only reason nothing happened was because the bank automatically declined the attempted charges for exceeding the card’s transaction limit. The incident comes just weeks after auditing startup Vaudit reported finding around $1.7 million in AI billing overcharges across $34 million worth of invoices, with many of the issues allegedly linked to Claude Code billing. The company also pointed to months of GitHub reports from developers describing inconsistent and contradictory Anthropic invoices. @aipost 🏴
