  "text_prompts": [
    {
      "text": "A photograph of fresh pizza with basil and tomatoes, from a traditional oven",
      "weight": 1
    }
  ]
}

All examples on this submit are primarily based on the pattern pocket book for Stability Diffusion XL 1.0, which might be discovered on Stability AI’s GitHub repo.

Generate photos utilizing SDXL 1.0

Within the following examples, we deal with the capabilities of Stability Diffusion XL 1.0 fashions, together with superior photorealism, enhanced picture composition, and the flexibility to generate real looking faces. We additionally discover the considerably improved visible aesthetics, leading to visually interesting outputs. Moreover, we show using shorter prompts, enabling the creation of descriptive imagery with larger ease. Lastly, we illustrate how the textual content in photos is now extra legible, additional enriching the general high quality of the generated content material.

The next instance reveals utilizing a easy immediate to get detailed photos. Utilizing just a few phrases within the immediate, it was capable of create a posh, detailed, and aesthetically pleasing picture that resembles the offered immediate.

textual content = "{photograph} of latte artwork of a cat"

output = deployed_model.predict(GenerationRequest(text_prompts=[TextPrompt(text=text)],
                                            seed=5,
                                            peak=640,
                                            width=1536,
                                            sampler="DDIM",
                                             ))
decode_and_show(output)

Subsequent, we present using the style_preset enter parameter, which is barely obtainable on SDXL 1.0. Passing in a style_preset parameter guides the picture era mannequin in the direction of a specific type.

Among the obtainable style_preset parameters are improve, anime, photographic, digital-art, comic-book, fantasy-art, line-art, analog-film, neon-punk, isometric, low-poly, origami, modeling-compound, cinematic, 3d-mode, pixel-art, and tile-texture. This checklist of fashion presets is topic to alter; discuss with the most recent launch and documentation for updates.

For this instance, we use a immediate to generate a teapot with a style_preset of origami. The mannequin was capable of generate a high-quality picture within the offered artwork type.

output = deployed_model.predict(GenerationRequest(text_prompts=[TextPrompt(text="teapot")],
                                            style_preset="origami",
                                            seed = 3,
                                            peak = 1024,
                                            width = 1024
                                             ))

Let’s attempt some extra type presets with completely different prompts. The following instance reveals a method preset for portrait era utilizing style_preset="photographic" with the immediate “portrait of an previous and drained lion actual pose.”

textual content = "portrait of an previous and drained lion actual pose"

output = deployed_model.predict(GenerationRequest(text_prompts=[TextPrompt(text=text)],
                                            style_preset="photographic",
                                            seed=111,
                                            peak=640,
                                            width=1536,
                                             ))

Now let’s attempt the identical immediate (“portrait of an previous and drained lion actual pose”) with modeling-compound because the type preset. The output picture is a definite picture made with out having any specific really feel that’s imparted by the mannequin, guaranteeing absolute freedom of fashion.

Multi-prompting with SDXL 1.0

As we’ve seen, one of many core foundations of the mannequin is the flexibility to generate photos by way of prompting. SDXL 1.0 helps multi-prompting. With multi-prompting, you may combine ideas collectively by assigning every immediate a selected weight. As you may see within the following generated picture, it has a jungle background with tall shiny inexperienced grass. This picture was generated utilizing the next prompts. You may evaluate this to a single immediate from our earlier instance.

text1 = "portrait of an previous and drained lion actual pose"
text2 = "jungle with tall shiny inexperienced grass"

output = deployed_model.predict(GenerationRequest(
                                            text_prompts=[TextPrompt(text=text1),
                                                          TextPrompt(text=text2, weight=0.7)],
                                            style_preset="photographic",
                                            seed=111,
                                            peak=640,
                                            width=1536,
                                             ))

Spatially conscious generated photos and adverse prompts

Subsequent, we have a look at poster design with an in depth immediate. As we noticed earlier, multi-prompting lets you mix ideas to create new and distinctive outcomes.

On this instance, the immediate may be very detailed when it comes to topic place, look, expectations, and environment. The mannequin can be attempting to keep away from photos which have distortion or are poorly rendered with the assistance of a adverse immediate. The picture generated reveals spatially organized objects and topics.

textual content = “A cute fluffy white cat stands on its hind legs, peering curiously into an ornate golden mirror. However within the reflection, the cat sees not itself, however a mighty lion. The mirror illuminated with a mushy glow in opposition to a pure white background.”

textual content = "A cute fluffy white cat stands on its hind legs, peering curiously into an ornate golden mirror. However within the reflection, the cat sees not itself, however a mighty lion. The mirror illuminated with a mushy glow in opposition to a pure white background."

negative_prompts = ['distorted cat features', 'distorted lion features', 'poorly rendered']

output = deployed_model.predict(GenerationRequest(
                                            text_prompts=[TextPrompt(text=text)],
                                            style_preset="improve",
                                            seed=43,
                                            peak=640,
                                            width=1536,
                                            steps=100,
                                            cfg_scale=7,
                                            negative_prompts=negative_prompts
                                             ))

Let’s attempt one other instance, the place we preserve the identical adverse immediate however change the detailed immediate and elegance preset. As you may see, the generated picture not solely spatially arranges objects, but additionally modifications the type presets with consideration to particulars just like the ornate golden mirror and reflection of the topic solely.

textual content = "A cute fluffy white cat stands on its hind legs, peering curiously into an ornate golden mirror. Within the reflection the cat sees itself."

negative_prompts = ['distorted cat features', 'distorted lion features', 'poorly rendered']

output = deployed_model.predict(GenerationRequest(
                                            text_prompts=[TextPrompt(text=text)],
                                            style_preset="neon-punk",
                                            seed=4343434,
                                            peak=640,
                                            width=1536,
                                            steps=150,
                                            cfg_scale=7,
                                            negative_prompts=negative_prompts
                                             ))
