From the Files API Reference page, referring to organization about storage:
Individual files can be up to 512 MB, and the size of all files uploaded by one organization can be up to 100 GB. Please contact us if you need to increase these storage limits.
From the Assistants documentation page, referring to both vector store usage and vision on the files endpoint:
By default, the size of all the files uploaded in your project cannot exceed 100 GB, but you can reach out to our support team to increase this limit.
Reaching out is sending a message through “help” on the platform site. The correct way. Glad to have figured it out for you.
Paying $5 into credits gets you 100GB. So does $1000+, months or years, and tier 5…so you do have an interesting point about scaling. The typical production app is chatbots, though, the only way you could talk to a vector store a week ago, and that gives you 100MB dynamically per each of your thousand customers to service them with 200 million tokens. And a vector storage bill for resulting 200GB = $20 a day. They’d probably up your limit when you are buying a new 1TB SSD a week in billings of idle data.
