OpenAI
Pick it if: Content creators and marketers who need text, image, and video generation in a single workflow
Its edge: The only commercial AI platform to exceed human expert performance on computer-use benchmarks (OSWorld 75% vs 72.4% human baseline) while also offering native image and video generation in the same subscription.
The catch: Complex, overlapping pricing tiers (6 plans) and $25B ARR growth have outpaced customer support infrastructure, resulting in unresolved billing disputes that dominate Trustpilot.
