TL;DR
The Information reported on Oct. 5 that Meta reduced employee use of Claude Code from about 60,000 to about 30,000, while Microsoft lowered a forecast of more than $1 billion in annual internal Anthropic spending by over a third. The reported moves concern internal use, not an end to Claude access or a confirmed rejection of Anthropic’s products on quality grounds. They show how large buyers can shift workloads when they have alternatives, while smaller firms may face substantial switching costs.
Meta and Microsoft have reportedly scaled back internal use or planned spending on Anthropic’s AI tools, directing employees toward alternatives including Meta’s own coding products, GitHub Copilot and OpenAI models. The Information reported the changes on Oct. 5; the developments matter as a sign of cost-conscious vendor switching, but do not show that either company has ended Claude access or judged it inferior.
According to The Information, Meta cut the number of employees using Claude Code from about 60,000 earlier this year to about 30,000. The report says Meta has steered staff toward MetaCode, which has passed 30,000 internal users, and Muse Code, which has passed 6,000. These figures describe employee use of the tools, not the number of external customers or a direct comparison of product quality.
The same report says Microsoft had projected more than $1 billion a year in internal spending on Anthropic technology, including Claude Code, Claude models in Copilot and Claude Mythos. It has since cut that projection by more than a third and directed employees toward GitHub Copilot and OpenAI models. The source material also reports that Microsoft continues to spend on Anthropic models for customer-facing Copilot features and that customer spending on Claude through Microsoft platforms is growing.
The reported explanation is cost and spending control, alongside access to substitutes, rather than a stated finding that Claude performs worse. A separate account cited in the source says some Microsoft team budgets fell from around $100,000 a month to around $10,000. That figure comes from a single report, and the source does not give enough detail to establish how widely the budget reductions applied.
Meta and Microsoft pulled back from Claude. Here’s what switching actually costs.
The Information reports both companies steering their own employees away from Claude. Read as a verdict on Claude, it misleads. Read as a demonstration of switching — and who can afford it — it’s the most useful enterprise-AI signal this month.
Staff steered to GitHub Copilot and OpenAI models; stricter token budgets. One unconfirmed report: some team budgets ~$100k → ~$10k/month.
Microsoft reportedly still spends heavily on Claude for customer-facing Copilot — and that spending is reported to be growing.
Reported drivers: rising token costs and owned alternatives. Neither company is reported to have called Claude worse.
Meta builds coding tools; Microsoft owns Copilot and backs OpenAI. This is ordinary vertical integration.

A few hundred tasks with pass criteria.
Logic, prompts, tools in your layer.
Tokens are the cheap half.
Know what you’d rebuild.
On the evidence reported, Meta and Microsoft didn’t reject Claude. They brought spending in-house where they could and kept buying where they couldn’t — Microsoft remains a large Anthropic customer for the products it sells. The signal is the mechanism: the most sophisticated buyers treat models as interchangeable suppliers behind a layer they control.Meta could halve its Claude usage because it had built somewhere else to go. Build somewhere else to go.
The Cost of Switching AI Tools
The reports illustrate a distinction between having the option to switch and being able to switch cheaply. Meta and Microsoft have alternatives in place, so they can redirect some employee work without relying on one external provider. The companies’ scale and engineering capacity may make that choice more practical than it would be for a firm with no deployed substitute.
For other organizations, a lower price per token may not mean a lower overall cost. A switch can require teams to rerun evaluations, adjust prompts and tool connections, retrain users and review output for quality. It can also disrupt established workflows. Those costs are not captured by an API price alone, and the reporting does not quantify them for either company.
The figures do not establish a broader verdict on Claude. They do, however, focus attention on how businesses manage dependence on AI vendors: whether they can compare models on their own work and redirect tasks if prices, budgets or availability change. That ability can have value even when a company chooses not to switch.

Alternatives Already in Place
Both firms named in the report have reasons to use tools other than Anthropic’s. Meta develops its own models and coding products; Microsoft owns GitHub Copilot and is a major backer of OpenAI. Those existing products give the companies potential substitutes for some internal work. They also mean the reported employee shifts take place within organizations that have commercial interests in competing AI tools.
The reported changes are limited to internal use and plans. They should not be read as proof that the companies have stopped using Anthropic technology across their businesses. The source says Microsoft continues to use Anthropic models for customer-facing Copilot features, while customer use through Microsoft platforms is reportedly growing. Internal procurement and customer-facing product choices are separate, and the available information does not give a complete account of either company’s total Anthropic usage.

What the Reports Do Not Establish
Neither company is reported to have said Claude performed worse, and the source material does not include statements from Meta, Microsoft or Anthropic confirming the decisions or explaining them directly. The exact current spending and usage figures, the timing of each change and the methods used to calculate them are not provided.
It is also unclear how much of the reported shift reflects price changes, internal budget limits, product strategy or differences in performance on particular tasks. The account of monthly Microsoft team budgets is attributed to a single report and should not be treated as a company-wide policy without further confirmation. The scale of any productivity effects or switching costs is not established, nor is the share of Microsoft’s customer-facing Anthropic use affected.

Evidence Needed on Usage and Costs
The next useful information would be direct confirmation from Meta and Microsoft about how their employee usage and Anthropic spending changed, which teams or products were affected, and what reasons shaped the decisions. Anthropic’s response, if any, could clarify whether the companies’ commercial arrangements or access have changed.
For buyers weighing similar choices, the reported moves make internal comparisons relevant: performance on representative work, review and rework time, integration effort, and the full cost of running each workflow. Until more detail is available, the report supports a limited conclusion: two large customers reportedly redirected some internal work toward alternatives they already had. It does not establish that Claude has been dropped or that switching will save money for other organizations.

Key Questions
Have Meta and Microsoft stopped using Claude?
The report does not say that either company has ended all Claude use. It describes reduced internal use or lower planned internal spending. The source says Microsoft continues to use Anthropic models in customer-facing Copilot features.
Why are the companies reportedly shifting internal work?
The reported reasons are rising token costs, tighter spending controls and available alternatives. The source does not report that either company said Claude’s quality was the reason.
How much did Microsoft reportedly cut its spending forecast?
Microsoft reportedly lowered a forecast of more than $1 billion a year in internal Anthropic spending by more than a third. The source does not provide a final spending figure.
Does this show Claude is worse than competing models?
No quality comparison is established by the report. It describes internal spending and tool-use decisions, with cost and in-house alternatives cited as the reported drivers.
What can smaller companies learn from the reported moves?
The reports highlight the value of measuring model performance on a company’s own tasks and understanding the cost of changing tools. Switching can involve engineering, evaluation and staff time, so a lower token price alone may not show the full financial effect.
