Microsoft has introduced MAI-Code-1-Flash for Copilot Business and Copilot Enterprise, with reports indicating the company is reducing its dependence on OpenAI models. The move is part of a broader push into AI, including the launch of seven new MAI models and potential changes to billing for GitHub Copilot. The developments suggest a shift in Microsoft's AI strategy, with some reports also mentioning partnerships and a possible transition to token-based billing.
