A respectable bake. You'd come back tomorrow for another.
Summary
Microsoft dropped its internal use of Anthropic's Claude Code after experiencing unsustainable budget overruns due to token-based billing for AI code-generation tools. The incident highlights a critical problem for enterprises adopting frontier AI APIs: the lack of predictable pricing and spend controls. This creates a counternarrative to Anthropic's $900B valuation, as its highest-profile enterprise user found the cost model unworkable. The article warns that without predictable pricing tiers or embedded spend controls, enterprise AI deals risk cancellation post-pilot regardless of product quality.
