Microsoft's Copilot Cowork moves to usage-based billing and may tap DeepSeek

Microsoft is transitioning its Copilot Cowork service to a usage-based billing model, citing the financial unsustainability of fixed-rate pricing. The company is also evaluating the integration of DeepSeek V4 as a lower-cost model option to optimize performance and overhead. This shift reflects a broader industry trend toward scaling AI costs in proportion to actual user consumption.
