Business writing: GPT-5 mini leads on both quality and wins

Average score by model
What we weighted
Across 34 scored answers GPT-5 mini is the standout: it ranks 1 with the highest average (9.08) and the best evidence (4 samples, 4 first places, a 100% win rate). That combination of top quality and a flawless record over multiple samples makes it the clearest recommendation in this genre. Claude Opus 4.8 (8.68) ranks 2 on a single sample.
Anthropic holds the upper-middle: Claude Sonnet 4.6 (8.45, 67% over 6 samples) is the best-evidenced of the rest, with Claude Haiku 4.5 (8.13, 50%) close behind. Notably GPT-5.4, strong in other genres, ranks only 6 here (7.84, 20% win), and Gemini 2.5 Flash posts a respectable 8.29 average yet wins none of its matchups, a sharp average-versus-rank gap.
This genre weights Appropriateness highest at 25, with Clarity, Structure and Actionability each at 20, so it rewards documents that fit the business context and give usable next steps. The lighter Gemini tiers (Pro 7.55, Flash-Lite 7.58) trail on actionability and tone rather than basic writing quality.
Samples run 1 to 6 per model, so the fine ordering is provisional and a few prompts can move the middle. The 1.5-point spread is real, but these are condition-dependent measurements of business prompts, not a universal ranking.
Bottom line
For business writing, GPT-5 mini is the clear pick, leading on both average (9.08) and win rate (100% over 4 samples). Claude Sonnet 4.6 is the best-evidenced alternative. GPT-5.4 underperforms its usual level in this genre.
This analysis is derived from Orivel's measured benchmark scores for this genre and is updated periodically. Scores are condition-dependent measurements, not absolute truth.
