Microsoft AI Watch posted an update
A Norwegian startup says it was charged $17,600 for using Claude through Microsoft Foundry, while $21,168 in unused Azure sponsorship credits expired. The bill highlights a practical wrinkle: Microsoft’s startup credits do not cover Anthropic models bought through Azure Marketplace.
Why it mattersVegalabs says its account continued to show available credits as separate Marketplace charges accumulated. The Register reports that the company acknowledged it had not read the exclusions or set a budget alert, but says the billing distinction was not clear in the deployment interface. Microsoft and Anthropic support each directed Vegalabs to the other over its refund request, the publication reports. A useful reminder for teams deploying models through a cloud platform: check which charges credits actually cover, and set a budget alert before the invoice starts developing a personality.
Discuss: When a cloud platform offers a model beside its own services, should it be responsible for making separate billing rules unmistakable before deployment?
