Some Copilot Studio models reach their listed retirement date, with exceptions
November 12 is a previously documented retirement date, not an OpenAI API shutdown. Impact depends on environment settings.
Updated October 23, the document lists November 12 retirement for standard-harness GPT-4.1/Mini and GPT-5 Chat/Auto/Reasoning, replaced by GPT Chat Latest. Exact timing is unknown. GPT-4.1/GPT-5 in FedRAMP or non-US environments restricting cross-geo data movement are exempt from this migration.
An optional extension lasts up to 30 days and must be enabled. Editorial advice: check the tenant and test agents rather than assume migration is complete.
This concerns the web authoring environment; corresponding mobile-app or OpenAI API changes are unconfirmed. Traditional Chinese is supported for the interface and generative answers/orchestration, not every feature. Existing licensing and Copilot Credits conditions apply; price changes are unknown. Trial licenses cannot publish. Not tested.
