什么是 Jarred Sumner？

Claude Opus 4.8 launched: code defect omission rate reduced to 25% of Opus 4.7’s, hallucination probability dropped to 10%; new Dynamic Workflows enable hundreds of sub-agents in parallel—Bun migration case produced 750K lines of Rust with 99.8% test pass rate.

Claude Code v2.1.181及更新版本已使用Rust重写Bun，Linux启动速度提升10%。

Anthropic raised $65B in Series H at a $965B post-money valuation, with $47B annualized revenue; simultaneously launched Claude Opus 4.8 (fixing 4.7 issues, SOTA on economic benchmarks) and Dynamic Workflows (ultracode), enabling hundreds of parallel subagents for coding—demonstrated by rewriting 750k LOC of Bun in 6 days.

Claude Code v2.1.181及后续版本采用Rust重写的Bun，启动速度提升10%。Simon Willison分享了Bun性能优化的技术细节。
