GPT‑5.2 Lands: Rolling Out to Microsoft 365 Copilot on Day One

It was the worst kept secret in the AI world, but today (maybe two days late according to some), OpenAI announced GPT-5.2, and Microsoft started rolling it out to Microsoft 365 Copilot and Copilot Studio on day one.

The aspect that caught my eye the most in OpenAI's introduction post were the side-by-side comparisons of different content formatting and interactive visual elements between GPT-5 and GPT-5.2. This is an area where the latest GPT models had really been outpaced by Claude and the later releases of Gemini over the course of this year (and probably the reason Microsoft's Frontier office app agents call Claude rather than GPT-5).

It seems that in this area, GPT-5.2 may have caught up, or maybe even overtaken. This is definitely an area that is really important to real world business uses that go beyond basic chat.

Another interesting advance which I saw pointed out by Timothy Lynch is the increase in performance in long context scenarios versus GPT-5.1. It continues to be my view that context limitations rather than intelligence are the biggest practical limiter for AI assistant efficacy in the majority of business scenarios, so increases here could drive big impact.

If you're interested in AI, you're probably already actively refreshing your ChatGPT and Copilot tabs to see if it's arrived yet. For everyone else, this is a step forward rather than a revolution. This will be helpful, and may the best, at least until Anthropic or Google strike back.
