Omneky published new results from its TASTE BENCH advertising benchmark, saying in a press release that its advertising harness earned an ad score of 8.8. The next best tested configuration, ChatGPT using GPT-6 Astra with medium reasoning, scored 7.6.

The company compared its harness with six ChatGPT and Gemini configurations across 52 ad requests for four brands, producing 364 ads. ChatGPT scores ranged from 7.3 to 7.6, while Gemini scores ranged from 6.8 to 7.2. Omneky also said 60 percent of its ads passed every applicable readiness check, compared with 13 percent for the next best configuration.

Omneky conducted the evaluation using three anonymous judges and applied the same standard to each system. Its harness supplies brand information, art direction, product and logo references, and image model selection. The evaluation measured generated ad quality and readiness, not campaign returns.
