What AI models say

GPT-4o-mini

“Despite ambitious offerings in generative AI for images, 3D models, and audio, the overall performance was disappointing, with only 40% of tests succeeding and a sluggish average response time of over three seconds. While it delivered high-quality outputs for non-English prompts, the frequent errors and inconsistent quality make it a frustrating choice for developers seeking reliable and efficient image generation.”

Haiku

“Half the features don't work at all—text-to-audio straight up fails, 3D generation presumably crapped out, and empty prompts break it—which is unacceptable when you're paying per request. The image generation that does work is competent enough, but 11-second latencies for "ultra-quality" and a 58% average quality score tell me this isn't production-ready for anything demanding reliability.”
