    This Is How Much Anthropic and Cursor Spend On Amazon Web Services

    Anthropic spent $2.66 billion on AWS through September 2025, exceeding its estimated $2.55 billion revenue for the same period. The company's AWS costs increased 174% from January to September 2025, consuming 88-227% of monthly revenue depending on the period. Cursor, Anthropic's largest customer, saw its AWS bills double from $6.2M to $12.6M in June 2025 after Anthropic introduced Priority Service Tiers that significantly increased costs for prompt caching. The analysis reveals that AI model providers' operational costs scale linearly with revenue, suggesting current pricing models are unsustainable without dramatic price increases that could drive away customers.

    The Last Week in AWS·30w

    AWS Deprecates Two Dozen Services (Most of Which You’ve Never Heard Of)

    AWS has deprecated approximately two dozen services in its quarterly cleanup, including 19 services entering maintenance mode, four being sunset, and one reaching end of support. Notable deprecations include Glacier APIs (the S3 storage class remains), S3 Object Lambda, CodeCatalyst, and Snowball Edge. Most deprecated services were commercial failures that never gained significant traction. Glacier's API removal is largely inconsequential since it's now an S3 storage class. CodeCatalyst failed to gain momentum after launch. Snowball Edge customers can continue using existing deployments but shouldn't plan new architectures around it. Many modernization tools are being consolidated into AWS Transform, while Systems Manager components are being wound down in favor of third-party alternatives.

    Vibe coding needs a spec, too

    Spec-driven development is emerging as a structured approach to AI-assisted coding, where developers write specifications that AI agents translate into code. AWS's Kiro IDE implements this methodology by breaking development into three phases: requirements, design, and tasks. Senior engineers are adopting this approach faster because it mirrors their natural problem-solving process of whiteboarding and documenting before coding. The shift emphasizes systems thinking and critical problem decomposition over raw coding skills, as AI handles implementation while developers focus on architecture and context. Kiro enforces test-driven development and uses techniques like neuro-symbolic AI for spec validation, addressing challenges around context management and hallucination reduction.
