Anthropic engineer explains why Claude's writing got worse although the model got smarter

An Anthropic engineer explains that recent Claude models' writing style has become denser and more technical due to optimization for math, code, and other AI-oriented tasks. Opus 5.5 attempts to address this, but Opus 4.6 remains the preferred choice for pure writing quality.
Why it matters
Understanding trade-offs in model optimization reveals that improving capabilities in technical domains can affect general usability and writing naturalness for humans.
