OpenAI names GPT-5.6 preferred model for Microsoft Copilot
OpenAI announced Thursday that its new GPT-5.6 model will become the preferred AI model for Microsoft's 365 Copilot. The move comes after reports that Microsoft was increasingly using its own in-house MAI models in apps like Word and Excel to cut costs. OpenAI's announcement aims to signal that the partnership remains strong, though it does not negate the earlier reporting about Microsoft's cost-cutting efforts.
