Microsoft Corporation is facing a proposed class-action lawsuit filed in San Francisco's federal court by consumers who allege the tech giant's partnership with OpenAI has led to illegally inflated prices for generative AI products. The lawsuit claims that Microsoft's exclusive cloud computing agreement with the creator of ChatGPT violated federal antitrust laws by restricting competition and artificially driving up subscription prices for the AI chatbot. The plaintiffs also allege that Microsoft leveraged the agreement to develop its own competing products, such as Copilot, while limiting OpenAI's access to necessary computational resources. In response to the lawsuit, Microsoft has stated that it is reviewing the matter and believes its partnership with OpenAI fosters innovation, competition, and the responsible development of artificial intelligence.
