Meta and Microsoft take steps to reduce employee usage of Claude AI

Meta and Microsoft are significantly reducing employee reliance on Anthropic's Claude AI, shifting focus to their own proprietary coding tools. This move, reported on October 5 by The Information, highlights a strategic pivot. Meta's internal tool, MetaCode, has over 30,000 users, while Muse Code, which began external client testing in August, boasts over 6,000 employee users. This transition underscores a broader industry trend towards in-house AI development and utilization.
