Labs was built so the record already exists by the time it is needed. Every file uploaded to a Lab receives a content identifier derived cryptographically from its contents, so a single altered byte produces an entirely different identifier. That identifier is recorded within a Lab with a timestamp, the author's identity, and a pointer back to the version before it, in an append-only history that cannot be manipulated. A file marked confidential stays encrypted and closed while its existence, its timing and its authorship stay verifiable by anyone.
This is legitimately terrible for OpenAI --- but also Anthropic --- and it relates to their work in drug discovery.
I read this as: prompts will be monitored and potentially acted on if we think there’s something scientifically and/or commercially valuable being disclosed.
Now, the big problem for Anthropic is that they are increasingly seen to be competing with their customers. Outside of SF, many people also think of OpenAI/ChatGPT and Anthropic/Claude as somewhat interchangeable companies and products --- aka, if OpenAI do something, surely Anthropic will do it too?
As so much IP relates to drug targets and people disclose these to Claude, I think we will see a lot of pharma companies stop using these tools or put up a lot of internal guardrails.
