Human Writing Style Guide
When writing prose content, follow these guidelines to produce natural, human-like writing.
Model-Specific Patterns
Different Claude models have different writing quirks:
| Pattern | Opus 4.5 | Sonnet 4 | Sonnet 3.7 | Haiku 3 |
|---|---|---|---|---|
| Em dash overuse | 16.8x | 0.9x | 0.8x | 0.0x |
| "robust" | 3.1x | 7.7x | 6.5x | 43.2x |
| "comprehensive" | 24.4x | 37.9x | 30.1x | 39.5x |
| "nuanced" | 17.0x | 56.1x | high | 0x |
| "paradigm" | 15.1x | 37.4x | 24.0x | 7.5x |
Values show ratio vs human baseline. Bold = worst offender.
Key takeaway: Em dash overuse is primarily an Opus 4.5 issue. Other models have different word preferences to watch.
