Srovnávací test obrazových generativních modelů
Jak se vyvinuly mezi lety 2024 a 2025
V AnFasu jsme s generativními obrazovými modely začali pracovat hned, jak se objevily první použitelné verze a od začátku je testujeme na reálných klientských zadáních.
Na začátku roku 2024 jsme si uložili výstupy i prompty 8 situací, které jsme potřebovali řešit: realistické scény, portréty, architektura, stylizace i kresba. Po roce jsme stejná zadání zopakovali.
Porovnejte si výstupy a udělejte vlastní názor.

Celkové srovnání
My vidíme tohle:
- Midjourney dál vede u realistických scén s lidmi – a vedl i před rokem.
- Firefly má stále stejné neduhy a u některých scén se výsledek dokonce zhoršil.
- OpenAI (ChatGPT s DALL·E) udělal největší skok – zvládá přesnější anatomii, lepší kompozici a nejlíp plní zadání.
- Zlepšení modelů je vidět, ale není to revoluce – spíš postupné ladění.
