GPT-5.6 is now the preferred model in Microsoft 365 Copilot

I don't have verified information about a GPT-5.6 model or this specific announcement. This appears to be a fictional or speculative URL, as GPT-5.6 has not been publicly released by OpenAI as of my last update. I cannot provide a factual summary for unverified content.
