Microsoft could discontinue Claude Code internally as it seeks to push users to GitHub Copilot

Claude models will remain available in Copilot CLI and other AI tools

Microsoft has reportedly canceled most of the Claude Code license it uses internally, although the Anthropic tool has become a hit with workers and the community at large.

Using Anthropic licenses may come as a shock given the company’s long history with and investments in OpenAI, but that could be about to change as the company shifts direction to offer its own alternative.

Engineers are now required to use GitHub Copilot CLI, with users having until June 30, 2026 to remove Claude Code from their workflows.

Microsoft tells engineers to use GitHub Copilot CLI, not Claude Code

Although the company has not publicly explained the reasons for its decision, the June 30 deadline corresponds to the end of Microsoft’s fiscal year. Switching to a company-owned alternative could provide huge savings.

GitHub Copilot CLI would provide tighter integration with Microsoft repositories and better alignment with its own enterprise security expectations, since Microsoft could effectively tailor GitHub to its own needs.

“Claude Code played an important role in this learning,” explained executive vice president Rajesh Jha (via The edge). “At the same time, Copilot CLI has given us something particularly important: a product that we can help shape directly with GitHub for Microsoft’s repositories, workflows, security expectations, and engineering needs. »

As for Claude Code, it seems that Anthropic’s alternative has met with great success among workers. Developers reportedly prefer it to Copilot CLI, and even non-engineers have started testing it. Microsoft had previously encouraged employees with limited coding knowledge to experiment with Claude Code.

Although GitHub will be the preferred ecosystem going forward, Claude models will remain available via Copilot CLI. In fact, the company has a growing partnership with Anthropic that even sees Claude models being offered through consumer-facing Copilot and M365 features, as it looks to diversify after a partial move away from OpenAI.
