TL;DR
The Information reported on Oct. 5 that Meta reduced employee use of Claude Code and Microsoft lowered a forecast for internal Anthropic spending, directing staff toward tools they own or back. Neither company is reported to have said Claude performed worse, and Microsoft reportedly continues to use Anthropic models in customer-facing products. The development highlights how costly and difficult switching AI tools can be for companies without ready alternatives.
Meta and Microsoft are steering some employees away from Anthropic’s Claude tools, according to a report by The Information on Oct. 5, redirecting internal work toward products they own or support. The reported moves point to cost controls and available substitutes, not a stated finding that Claude is inferior, and do not indicate that the companies have ended customer access to Anthropic models.
Meta reportedly reduced the number of employees using Claude Code from about 60,000 to about 30,000 compared with earlier this year. The report says staff are being directed toward Meta’s own coding tools: MetaCode, which has more than 30,000 internal users, and Muse Code, with more than 6,000. These figures describe internal employee use, not the number of customers using Meta products.
Microsoft had reportedly projected spending more than $1 billion a year on Anthropic technology for internal use, including Claude Code, Claude models in Copilot and Claude Mythos. The Information reported that Microsoft cut that projection by more than a third and is guiding employees toward GitHub Copilot and OpenAI models. A separate detail in the source report says some monthly team budgets fell from about $100,000 to about $10,000; that figure is attributed to a single account and should not be treated as a company-wide budget rule.
The reported changes concern internal use and projected spending. Microsoft is still reported to use Anthropic models in customer-facing Copilot features, while customer spending on Claude through Microsoft platforms is said to be growing. Neither report says that Claude access has been withdrawn or that either company publicly judged its performance to be worse.
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.
Keep a second vendor live on real work.
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.
For businesses using AI, the report is less a verdict on one model than a reminder that vendor choice can change quickly when costs rise or internal priorities shift. Meta and Microsoft can redirect work because they have alternatives already in use. Their options include products developed in-house or tools linked to their broader commercial relationships.
Other companies may not have that flexibility. Moving a workflow can require new evaluations, prompt and tool changes, integration work and time for staff to adapt. It can also affect the quality of results and the amount of human review needed. Those costs may not appear in a model’s price per token, but they can affect the total cost of getting an acceptable result.
The report’s figures also show why internal adoption and customer availability are different questions. A company can reduce its own employees’ use of a supplier’s tools while continuing to offer that supplier’s models to customers. Readers should not interpret an internal shift as evidence that Claude is being removed from products or that all enterprise customers should make the same change.

Why These Buyers Have Alternatives
Meta and Microsoft are not ordinary customers in this market. Meta develops its own AI models and coding tools. Microsoft owns GitHub Copilot and is a major backer of OpenAI. That means each has potential alternatives to a third-party supplier, as well as commercial reasons to direct some employee activity toward its own products or partners.
The source material frames the reported moves around rising token costs, spending controls and in-house tools. It does not report a public statement from either company that Claude’s quality caused the shift. The distinction matters: a buyer can move work because of price or strategy without concluding that the product it leaves is technically worse.
The reported usage and spending figures are not a complete account of either company’s AI procurement. They describe particular internal tools and a projected Microsoft spending figure, rather than total AI spending or a decision to end all use of Anthropic technology.

What the Report Leaves Open
The reporting, as presented in the source material, does not include public confirmation from Meta or Microsoft of every usage count, spending projection or reported budget change. The precise timing and scope of the reductions, how the companies define active use, and whether the figures cover all teams are not clear.
It is also unknown how much of the projected savings will be realized after accounting for the costs of moving workloads, maintaining alternative tools and reviewing their outputs. The report gives no comparative evaluation results for Claude, MetaCode, Muse Code, GitHub Copilot or OpenAI models on the companies’ internal tasks. That means the reported shifts do not establish which tool performs best for any particular workflow.
Microsoft’s ongoing use of Anthropic models in customer-facing products is reported, but the source material does not specify which features rely on them, how usage may change, or how customer demand is measured. The developments should be understood as reported internal changes, not a confirmed end to the companies’ relationships with Anthropic.

Track Spending and Product Use
The next useful signals will be whether Meta and Microsoft confirm the reported figures, and whether later reporting shows further changes in internal use, budgets or customer-facing products. Any update should distinguish employee adoption from commercial availability and planned spending from actual spending.
For organizations making their own AI decisions, the practical response is not necessarily to switch providers. It is to learn what a change would involve before it becomes urgent: test more than one model on representative work, keep records of the results, and account for review and rework alongside token charges. Those steps can help buyers compare alternatives without assuming that a lower model price automatically means lower operating costs.

Key Questions
Have Meta and Microsoft stopped using Claude?
No such complete cutoff is reported. The account describes a reduction in some internal use and projected spending. Microsoft is also reported to continue using Anthropic models in customer-facing Copilot features.
Did the companies say Claude performs worse?
The source material does not report that either company said Claude performed worse. It describes cost, spending controls and available alternatives as the reported reasons for redirecting some employee work.
How much did Meta reportedly reduce Claude Code use?
The Information reported that the number of Meta employees using Claude Code fell from about 60,000 earlier this year to about 30,000. The figures concern internal employee use, and their precise scope has not been independently detailed here.
What was Microsoft’s reported spending change?
Microsoft had reportedly projected more than $1 billion a year in internal Anthropic spending and later cut that projection by more than a third. That is a reported change to a projection, not a confirmed measure of final annual spending.
What should other companies take from the report?
The report does not establish that other businesses should leave Claude. It shows that switching can be easier for companies with deployed alternatives; other buyers may need to account for testing, integration, staff adjustment and output quality before estimating savings.
