Microsoft phases out expensive AI models in Copilot cost-cutting move
Microsoft has begun phasing out third-party AI models, such as those from OpenAI and Anthropic, within its Copilot service. The primary objective is to reduce costs by replacing them with proprietary, more cost-effective solutions.
What happened?
Microsoft Copilot, the AI-driven assistant, is undergoing a transition where the company is phasing out the use of external AI models from providers like OpenAI and Anthropic. Priority is now being shifted to Microsoft's own optimised models. This strategy is being implemented to streamline operations and lower the substantial costs associated with running the Copilot service.

”Copilot goes cheap as Microsoft phases out OpenAI and Anthropic models to cut costs”
Why it matters
The decision reflects a growing trend among tech giants to internalise AI development to achieve better control over costs and performance. Relying on third-party models involves licensing fees and dependencies that can become unsustainable at scale. By developing and deploying proprietary models, Microsoft can also fine-tune Copilot for specific use cases, potentially improving both efficiency and the user experience.
Who is affected?
This shift primarily affects end-users of Microsoft Copilot, who may notice changes in the assistant's behaviour or performance due to the new models. Developers building applications on top of Copilot may also need to adapt to potential API changes. OpenAI and Anthropic lose a major customer, which could influence their market strategies and revenue streams.
What else you should know
Microsoft has invested significant resources into its own AI research and development, enabling this transition to internal models without a total loss of functionality.
