Microsoft is testing Kimi K3 inside Copilot, with claims of up to 60% lower inference cost

Microsoft is reportedly in the process of adding Kimi K3 to Azure and testing it inside Copilot for features that currently run on OpenAI and Anthropic models.
- The report says Microsoft engineers are evaluating whether Kimi K3 can power flagship Copilot features.
- A source cited in the image says the company has already tested other open-source models, including older DeepSeek and Kimi models.
- The appeal is cost: the post claims Kimi K3 could cut inference spend by up to 60% per token.
- If Microsoft later self-hosts the open-source model, the cost could fall even further.
