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

Average score by model
What we weighted
Across 36 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 (8.83) ranks 2 on just 2 samples and also wins 100%, so its second place is promising but still lightly evidenced.
Anthropic holds the upper-middle: Claude Sonnet 4.6 (8.45, 66.7% over 6 samples) is the best-evidenced of the rest, with Claude Haiku 4.5 (8.13, 50%) close behind. The genre is full of average-versus-rank gaps: GPT-5.4, strong elsewhere, ranks only 6 (7.84, 20% win) and sits below Gemini 2.5 Pro (7.55, 25%) despite the higher average, while Gemini 2.5 Flash posts a respectable 8.29 yet wins none of its matchups and lands at rank 7.
This genre weights Appropriateness highest at 25, with Clarity, Structure and Actionability each at 20 and Tone at 15, so it rewards documents that fit the business context and give usable next steps. That is why win rate, not average, drives the order: Flash's polished-but-unfitting answers lose head-to-head. Gemini 2.5 Flash-Lite trails last (7.38, 0% over 6 samples), and the top-to-bottom spread is 1.7 points.
Samples run 1 to 6 per model, so the fine ordering is provisional and a few prompts can move the middle. The leader's edge over second is only 0.25, and single-sample results like GPT-5.5 (7.73) are unconfirmed. 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; Opus 4.8's second place rests on only 2 samples. GPT-5.4 underperforms its usual level here.
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.
