Microsoft is reportedly weighing whether to replace ChatGPT and Claude with Moonshot’s Kimi K3 to cut $600 million in costs.

The report frames the move as a procurement and cost-optimization decision rather than a model launch. If true, it would underscore how fast large buyers are now benchmarking frontier models against each other on price/performance and switching costs, not just headline capability.

The story is being circulated through an MSN link and is not an official Microsoft announcement.
