MSFT gained almost 4% today because they announced a higher-than-expected price for Microsoft Office 365 Copilot, which has AI features built in. The AI uses the same Large Language Model (LLM) as Open AI's ChatGPT. For example, Copilot includes a feature called Business Chat. According to the company,

"Business Chat works across the LLM, the Microsoft 365 apps, and your data ' your calendar, emails, chats, documents, meetings and contacts ' to do things you've never been able to do before. You can give it natural language prompts like 'Tell my team how we updated the product strategy,' and it will generate a status update based on the morning's meetings, emails and chat threads."

This is going to be a productivity game changer. For example, today's LLMs can take a set of meeting notes, and generate a TODO list of action items from the tasks discussed in the notes. You can also do things like generate a 2-paragraph Executive Summary from a 10-page strategy document.

Copilot "will cost $30 per user per month on top of what most business customers already pay." So it's almost double what business users pay today per user.

"Microsoft's Chief Financial Officer Amy Hood has said the company's new AI products will become the software company's fastest business to hit $10 billion."
