Omneky Harness Outperforms ChatGPT and Gemini on TasteBench Ad Score

Omneky leads with an ad score of 8.8 compared with 7.6 for the next best tested configuration

SAN FRANCISCO, Oct. 13, 2026 /PRNewswire/ -- Omneky, an AI advertising platform, today announced that its advertising harness earned the highest ad score in the TasteBench evaluation, scoring 8.8 and outperforming all six tested ChatGPT and Gemini configurations. The next-best configuration, ChatGPT using GPT-6 Astra at medium reasoning, scored 7.6.

Across the tested configurations, ChatGPT ad scores ranged from 7.3 to 7.6 and Gemini scores ranged from 6.8 to 7.2. Omneky led the nearest competitor by 1.2 points. The comparison covered 52 ad requests across four brands, producing 364 ads for evaluation.

The results highlight the role of the harness in creative production. A harness is the software surrounding a model that supplies context and directs its work. Omneky's advertising workflow reads brand information, develops art direction, provides product and logo references, and selects an image model. TasteBench compares the ads produced by these complete workflows.

"Creative is one of the most important levers for growth, and the quality of the finished ad matters to every marketer," said Hikari Senju, founder and CEO of Omneky. "We built Omneky's harness to bring brand knowledge and creative direction into every generation. TasteBench gives marketers a way to compare the quality of what these systems actually produce."

Omneky also led the separate readiness measure: 60% of its ads passed every applicable check, compared with 13% for the next-best configuration. This supporting metric measures whether an ad meets all of the benchmark's required checks.

Omneky conducted the evaluation with three anonymous judges, applying the same standard to each tested system. ChatGPT and Gemini runs used APIs with web search and image generation; app spot-checks produced similar results. The findings assess generated creative and do not measure campaign returns.
