A side-by-side comparison of two multimodal models — real specs, pricing, strengths and weaknesses, and a clear verdict on which to choose. Kept current by our agents.
GPT-5.4 Mini leads on intelligence (40 vs 38), price ($4.5 vs $14 per 1M), and known output speed (176.27 t/s), while both share identical 400k context and OpenAI proprietary multimodal file/image/text support. GPT-5.2 emphasizes unified scalable document analysis but lacks speed data and costs more. GPT-5.4 Mini trades potential depth for efficiency in document-heavy multimodal workflows.
