Why Anthropic Bought Bun
- Anthropic acquired Bun to ship the Claude Code SDK with a fast, compact JavaScript runtime.
- Owning Bun lets Anthropic optimize runtime features and performance for AI-driven code execution.
Bun's Unique Appeal
- Bun's unique, nonstandard features and Zig implementation make it attractive for quick scripts and small apps.
- Fast local runtime for AI-driven code execution is a key use case beyond just local developer ergonomics.
Runtime Speed Matters For LLMs
- LLMs often run code (scripts) behind user-facing responses, so a tiny, fast runtime matters for latency.
- Anthropic likely sees Bun as a nucleus to run model-invoked code both locally and remotely.
