Let us deep dive into the key updates for this model.

Key Features and Benefits

The model generates images at upto 2K resolution, making it an ideal choice for high fidelity use cases. The outputs are crisp and can be upscaled using ESRGAN or other image upscalers to make them print and digital screen ready. The speed of generation has also improved, letting you generate super high quality images within 10 seconds.

The model's prompt understanding has also improved. It can now create complex layouts like banners with a high degree of precision. It can follow the prompts accurately to generate detailed vivid imagery. The model also has enhanced aesthetics and structural quality in it's outputs.

The bigges leap is in it's ability to generate accurate small text and long text strings. The race began when GPT Image showed long text being rendered accurately, and now with this model, the user has another image generator model option to generate long text accurately.

All of these updates are reflected in multiple evaluations and rankings, making one of the top contenders of best overall image generators out there in the market.

Tips for Optimal Use

To get the best results, be specific with your prompts, focusing on specific descriptors for commercial or multi-object scenes.
