Key Takeaways
Microsoft Corp. is canceling internal access to Anthropic's Claude Code, an AI-powered programming tool, after its token-based billing model led to unexpectedly high costs. The move signals a broader enterprise reckoning with the true price of generative AI, even for a company with deep investments in the technology.
"As we began offering both Copilot CLI and Claude Code, the goal was to learn quickly, benchmark these tools in real-world engineering workflows, and understand what best supports our teams," Rajesh Jha, Microsoft's executive vice president of Experiences + Devices, said in an internal memo. While calling Claude Code an "important part of this learning process," Jha emphasized that Copilot CLI is a product Microsoft can "shape directly with GitHub to better suit" its internal needs.
The decision comes as the real-world costs of deploying AI models at scale are creating budget crises. AI software prices in the U.S. have risen 20 to 37 percent over the past year, and Microsoft's own GitHub is shifting away from fixed-rate plans toward usage-based billing. The problem is not isolated; Uber Technologies Inc. reportedly burned through its entire AI budget for the year in just four months, largely due to widespread adoption of Claude Code within its engineering teams.
This pullback highlights a critical tension in the AI market. For model providers like Anthropic, which recently surpassed OpenAI in business adoption for the first time according to a Ramp analysis, widespread use is a validation. However, the sticker shock from token-based pricing is forcing their largest customers to cap usage. This threatens the revenue growth needed to justify high valuations and potential IPOs. The alternative is for AI labs to lower prices and absorb the losses, worsening their unit economics.
Microsoft's decision is not just about cost control; it's about competitive positioning. The company, which has invested $13 billion in OpenAI and provides significant cloud resources to Anthropic, found its own GitHub Copilot CLI losing ground internally to Claude Code. Despite 91% of its engineering teams using GitHub Copilot before the introduction of Claude, the Anthropic tool became highly popular among Microsoft's developers over the past six months for its perceived advantages.
To manage the transition, Microsoft is requiring engineers to migrate their workflows to GitHub Copilot CLI by the end of June. This has reportedly put immense pressure on the GitHub team to rapidly iterate on Copilot CLI, addressing bug reports and feature requests from internal users to close the gap with Claude Code before the deadline.
In response to growing customer concerns about unpredictable costs, Anthropic has announced a new /usage command for Claude. The feature provides detailed breakdowns of token consumption by different components, offering the transparency needed for teams to optimize prompts, disable costly tools, and manage their budgets more effectively.
