AI model providers
AI provider sub-processor terms, side by side
How much notice six AI model providers give before adding a sub-processor, and where each publishes its list, quoted with the date read.
Each provider’s DPA states a period for a new sub-processor. Some give you that long to object once they tell you; others promise that much notice before the new company starts.Of these six, five state a period to object and one a notice period.Each is quoted from the provider’s own document with the date we read it; we do not score or rank them.

How this page stays current
The pages quoted here are re-read on a schedule and every reading is kept as a dated, hashed copy. The quotes on this page are read from those copies when the page is served, so a rewritten clause appears here as the new wording, and the change appears on the provider’s record. How the record is kept.

What this page is not
It is not legal advice, and it is not your agreement. It quotes published documents on the dates shown; a signed agreement or negotiated addendum with a provider governs.
