2026 September Subprocessor Update: TypeSafe (non-enterprise plan)

View evidence

LangChain announced that Typesafe will be added as a subprocessor effective September 26, 2026, to provide inference for the Jev model via Gateway Credits on non-enterprise plans. Gateway Credits is explicitly unavailable on Enterprise plans, and the use of the Typesafe subprocessor is opt-in, requiring customers to explicitly select the model ID.

WHY IT MAY MATTER
