Microsoft has added Claude Sonnet 5, an AI model built by Anthropic, to its Copilot assistant, according to a report from Let's Data Science surfaced via Google News.
Copilot is Microsoft's AI helper that appears across its products, and the move means the model powering some of those interactions can now come from Anthropic, the company behind the Claude family of models. Sonnet is Anthropic's mid-tier line, positioned to balance speed and capability.
The available source is a single brief report, so the finer points — which Copilot features use the model, whether it is offered to all users or a subset, and the terms of the arrangement — are not spelled out in the material provided here. Readers should treat those specifics as unconfirmed until Microsoft or Anthropic publishes more detail.
What is clear from the report is the headline fact: a well-known Anthropic model is being integrated into one of the most widely deployed AI assistants on the market.
Why it matters: giving a mainstream product like Copilot access to a model from a rival AI lab is a signal that big platforms are increasingly willing to mix and match the best available models rather than rely on a single supplier.
