Developed by: PixArt-Σ Model type: Diffusion-Transformer-based text-to-image generative model Model Description: This is a model that can be used to generate and modify images based on text prompts. It is a Transformer Latent Diffusion Model that uses one fixed, pretrained text encoders (T5)) and one latent feature encoder (VAE).

Example prompts

Great starting points for PixArt-Sigma.

Imagine an ultra-HD, fantastical world where floating islands hover in the sky, connected by glowing bridges made of light. Waterfalls cascade off the edges of the islands, but instead of falling to the ground, the water disappears into a shimmering mist before reaching the bottom. The islands are covered in lush, alien vegetation, and the sky is filled with multiple moons and swirling galaxies. Describe the scene, highlighting the surreal beauty and the sense of wonder.
Picture an ultra-HD, frozen moment in time on a battlefield where warriors and creatures are suspended mid-action. Swords are locked in combat, arrows hang in the air, and magical energy glows in vibrant colors, frozen like lightning. The ground is cracked and glowing with energy, and the sky is a swirling mix of day and night. Describe the scene, focusing on the dynamic poses, the glowing energy, and the sense of a moment frozen forever.
Envision an ultra-HD, futuristic desert where colossal mechanical animals roam the sands. These creatures are made of polished metal and glowing circuits, with gears and pistons visible beneath their transparent skin. The sun reflects off their surfaces, creating dazzling light patterns. In the distance, a massive mechanical whale floats above the dunes, casting a shadow over the landscape. Describe the scene, focusing on the intricate details of the animals and the vast, otherworldly desert.
Picture an ultra-HD, unrealistic underwater world where a massive active volcano sits at the center of a bioluminescent forest. The lava glows bright orange, contrasting with the neon blue and green plants that sway in the current. Schools of glowing fish dart through the water, and giant, translucent jellyfish float above the forest. Describe the scene, emphasizing the surreal beauty and the interplay of light and shadow.
A fierce, otherworldly warrior woman with iridescent, holographic hair that shifts colors from violet to emerald. Her eyes glow with an ethereal light, and intricate metallic tattoos pulse with energy on her skin. She stands atop a floating island made of crystal and neon, surrounded by swirling cosmic clouds and digital glitches. In the distance, towering alien structures loom, bending the laws of physics. Ultra HD details highlight every strand of her hair, the gleam of her armor, and the surreal landscape behind her.
