Microsoft is testing its own AI model, MAI-1-preview, to reduce its reliance on OpenAI's technology for its Copilot assistant. The model is currently being evaluated on LMArena and aims to enhance Microsoft's AI offerings while competing with other major players in the field. Microsoft continues to support OpenAI but acknowledges the growing competition between the two companies.

Microsoft has launched a new AI browser that closely resembles OpenAI's recently unveiled Atlas, raising questions about originality and competition in the AI space. The new browser incorporates advanced features and functionalities that mirror those of Atlas, highlighting the rapid evolution and intense rivalry among tech giants in artificial intelligence development.
