Reality

Announcement strategic response to DeepSeek R1. Opus delayed to February for additional safety testing. Sonnet 4 benchmarks strong but not transformative over 3.5. Context window 200K confirmed.

Implication

Maintained Anthropic competitive position. But DeepSeek timing diminished impact. Market shifted from "who has reasoning" to "who optimizes cost/performance."
