  "steps": 50,
  "seed": 42,
  "sampler": "K_DPMPP_2M",
  "text_prompts": [
    {
      "text": "A photograph of fresh pizza with basil and tomatoes, from a traditional oven",
      "weight": 1
    }
  ]
}

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

Generate photographs 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 life like faces. We additionally discover the considerably improved visible aesthetics, leading to visually interesting outputs. Moreover, we exhibit using shorter prompts, enabling the creation of descriptive imagery with higher ease. Lastly, we illustrate how the textual content in photographs 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 photographs. Utilizing only some phrases within the immediate, it was capable of create a fancy, 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,
                                            top=640,
                                            width=1536,
                                            sampler="DDIM",
                                             ))
decode_and_show(output)

Subsequent, we present using the style_preset enter parameter, which is simply out there on SDXL 1.0. Passing in a style_preset parameter guides the picture era mannequin in direction of a selected model.

A number of the out there 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 favor presets is topic to alter; confer with the newest 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 model.

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

Let’s attempt some extra model presets with totally different prompts. The following instance reveals a mode 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,
                                            top=640,
                                            width=1536,
                                             ))

Now let’s attempt the identical immediate (“portrait of an previous and drained lion actual pose”) with modeling-compound because the model 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 favor.

Multi-prompting with SDXL 1.0

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

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

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

Spatially conscious generated photographs and destructive 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 also be making an attempt to keep away from photographs which have distortion or are poorly rendered with the assistance of a destructive 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 tender glow towards 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 tender glow towards 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,
                                            top=640,
                                            width=1536,
                                            steps=100,
                                            cfg_scale=7,
                                            negative_prompts=negative_prompts
                                             ))

Let’s attempt one other instance, the place we hold the identical destructive immediate however change the detailed immediate and elegance preset. As you may see, the generated picture not solely spatially arranges objects, but additionally adjustments the model 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,
                                            top=640,
                                            width=1536,
                                            steps=150,
                                            cfg_scale=7,
                                            negative_prompts=negative_prompts
                                             ))

Face era with SDXL 1.0

On this instance, we present how SDXL 1.0 creates enhanced picture composition and face era with life like options similar to fingers and fingers. The generated picture is of a human determine created by AI with clearly raised fingers. Notice the small print within the fingers and the pose. An AI-generated picture similar to this is able to in any other case have been amorphous.

textual content = "Picture of an previous man with fingers raised, actual pose."

output = deployed_model.predict(GenerationRequest(
                                            text_prompts=[TextPrompt(text=text)],
                                            style_preset="photographic",
                                            seed=11111,
                                            top=640,
                                            width=1536,
                                            steps=100,
                                            cfg_scale=7,
                                             ))
