Details
- Microsoft says Anthropic’s Claude Opus 5.5 and OpenAI’s GPT-6 Sol are rolling out in Microsoft Copilot.
- The models will be available across Word, Excel, PowerPoint, Chat, Cowork, and Copilot Studio.
- Users can select the model that best matches a task, expanding Copilot’s existing model-choice capabilities.
- Microsoft’s Work IQ supplies organizational context from files, meetings, chats, and other business data.
- Work IQ is intended to ground responses in an organization’s information rather than relying on a model alone.
- Availability may vary by license, access level, and region.
- The update extends Microsoft’s strategy of combining models from multiple providers within its productivity and agent platforms.
Impact
The rollout strengthens Microsoft’s position as a distribution layer for competing frontier models while reducing customers’ need to choose a single AI provider. Model choice paired with Work IQ could make Copilot more useful for specialized work, but licensing, regional availability, and data-processing requirements will determine how broadly enterprises adopt the feature. It also increases competitive pressure on standalone assistants by embedding Anthropic and OpenAI capabilities directly into Microsoft’s workplace software.
