Microsoft begins axing Claude Code licenses

Microsoft is redirecting thousands of its internal developers from Anthropic's AI coding tool, Claude Code, to its own GitHub Copilot CLI. Since December, Microsoft had provided access to Claude Code, inviting employees, including project managers and designers, to experiment with coding. The tool quickly gained significant popularity within the company over the past six months, perhaps even exceeding expectations, leading Microsoft to now scale back its deployment.

The company reportedly plans to revoke the majority of its Claude Code licenses, encouraging many developers to transition to Copilot CLI instead. While Claude Code proved to be a favored tool, its widespread adoption inadvertently overshadowed Microsoft's newly introduced GitHub Copilot CLI—a command-line iteration of GitHub Copilot designed to operate independently of integrated development environments like Visual Studio Code.

Microsoft's Experiences + Devices team, which encompasses engineers responsible for core products such as Windows, Microsoft 365, Outlook, Microsoft Teams, and Surface, is slated to discontinue its use of Claude Code by the end of June. Sources indicate that engineers are being prompted to initiate the shift of their workflows to GitHub Copilot CLI in the coming weeks, ahead of this deadline.

Internally, Microsoft attributes this decision to a strategic move towards consolidating Copilot CLI as the primary "agentic command line interface tool" across its Experiences + Devices division. However, sources suggest a significant financial motivation behind the change. The June 30th cutoff coincides with the end of Microsoft's current fiscal year, making the cancellation of Claude Code licenses an expedient method to reduce operating expenses as the new fiscal year commences in July.

Rajesh Jha, executive vice president of Microsoft's experiences and devices group, articulated the company's perspective in an internal memo, stating, "When we began offering both Copilot CLI and Claude Code, our goal was to learn quickly, benchmark the tools in real engineering workflows, and understand what best supported our teams." He added, "Claude Code was an important part of that learning… at the same time, Copilot CLI has given us something especially important: a product we can help shape directly with GitHub for Microsoft’s repos, workflows, security expectations, and engineering needs."

Despite the strategic reasoning, the transition away from Claude Code is anticipated to pose challenges for Microsoft engineers. Claude Code had been actively promoted to employees without prior coding experience, enabling designers and project managers to rapidly prototype ideas. Initially, Microsoft had encouraged the simultaneous use of both Claude Code and GitHub Copilot to facilitate comparison and gather feedback.

However, Microsoft's developers ultimately demonstrated a preference for Claude Code over GitHub Copilot CLI in recent months, highlighting existing functional disparities between the products that now require urgent attention. Reportedly, Microsoft had even considered acquiring Cursor to bridge these gaps in GitHub Copilot but has since begun exploring alternative AI startups to advance its AI ambitions while navigating potential regulatory scrutiny.

Jha further emphasized the collaborative effort, stating, "We are partnering closely with GitHub and continue to improve Copilot CLI for Microsoft engineers." He confirmed, "The GitHub team has already shipped significant improvements based on Microsoft feedback, and Experiences + Devices will remain closely involved in shaping the product. This is a shared accountability across GitHub and E+D leadership: to make Copilot CLI the best agentic coding experience for Microsoft engineers."

Looking ahead, Copilot CLI will continue to provide access to Anthropic's models, alongside Microsoft's internal models and OpenAI's suite of offerings. Microsoft intends to significantly increase its investment in Copilot CLI, aiming for deep integration within its engineering workflows. Developers are also being urged to submit bug reports and feedback for Copilot CLI prior to the removal of Claude Code.

It is worth noting that Microsoft emerged as a key customer for Anthropic earlier this year, reportedly even attributing sales of Anthropic AI models towards its Azure sales quotas. Furthermore, a deal signed in November grants Microsoft Foundry customers access to specific Anthropic models, including Claude Sonnet 4.5, Claude Opus 4.1, and Claude Haiku 4.5.

This decision to cancel Claude Code licenses will not impact the existing Foundry deal. Microsoft employees continue to favor Anthropic's Claude models within Microsoft 365 applications and Copilot for certain tasks where they demonstrate superior capabilities compared to OpenAI's counterparts. Microsoft also recently collaborated with Anthropic to integrate the technology behind Claude Cowork into Microsoft 365 Copilot.

The onus is now on Microsoft's GitHub team to enhance Copilot CLI, with the ultimate goal of surpassing Claude Code's capabilities. While Microsoft previously reported that 91 percent of its engineering teams were utilizing GitHub Copilot last year, the extensive use of Claude Code over the past six months undoubtedly affected this figure. Microsoft is now focused on revitalizing GitHub Copilot usage and empowering its own engineers to contribute to the ongoing improvement of its proprietary AI coding tool.
