Stable Diffusion開発元の、Stability AI Japan — External AdvocateのD̷ELLと申します。
今回、Stable Diffusion最高モデル Stable Diffusion 3 80億パラメータ（8B） を搭載したAPI「Stable Image」の、最上位サービス 「Stable Image Ultra」 の体験会を実施しました。
実施内容をレポートにまとめましたので、報告させて頂きます。

概要

  • Stability AIからStable Diffusion 3 2B のモデルがリリースされ、世界を席巻した
  • Stability AI APIでは、最上位モデルの Stable Diffusion 3 8B が利用可能
  • 性能を体験してもらうために、色んな人に利用してもらったら凄かった

経緯

先日、Stability AIから待望の Stable Diffusion 3 Medium（2Bモデル）が発表され、大きな話題を呼びました。しかし、 Stability AI APIではさらに上位の Large / Ultra（8Bモデル） が利用できることをご存知でしょうか？

先日モデルリリースされた Stable Image Medium は 2B モデルですが、Stable Image Large は その4倍のパラメータを持つ 8Bモデルです。Stable Image Ultra は、8BモデルであるLargeを調整して更に性能を向上させた、名実ともに 全世界最高･最上位の画像生成AI となります。

Stable Image Ultraの紹介は以下の通りです。

当社の最も高度なテキストから画像への生成サービスであるStable Image Ultraは、これまでにない迅速な理解で最高品質の画像を作成します。Ultraは、タイポグラフィ、複雑な構図、ダイナミックな照明、鮮やかな色合い、芸術作品の全体的なまとまりや構成に優れています。Stable Diffusion 3を含む最先端のモデルから作られたUltraは、Stable Diffusionのエコシステムの最高峰を提供します。

Stable Diffusion 3 8Bの性能を最大限に引き出すように調整されたAPI、ということですね。

その優れた性能をぜひ体験していただきたく、先日Google Colabファイルを提供させていただきました。 こちら からご確認いただけます。

コメント：「SD3を使ってみて、先日公開されたmediumよりも良い感じに生成できて楽しかったです。これまでにSD1、SD2、XL、cascadeと試してきましたが、SD3はそれらの良いところをうまく取り入れているように感じました。プロンプトの効きと生成結果がとてもよく、体験としては非常に素晴らしかったです。まだultraはAPIのみでの利用ですが、APIに抵抗がない方にはぜひ試してみてほしいです。」

illustrated in an anime style with the focus on the upper body, from a slightly angled front view. A Japanese woman wearing a lace trimmed blue evening dress off shoulder style is sitting at the counter of a luxury hotel’s top-floor bar. The dress shows a collarbone and the feminine curves of her body. She is wearing a jewely necklace and has her silver hair up and red eyes. With a melancholic expression, she gazes out at the fog and rainy skyscraper cityscape through the window. The woman is holding an envelope in her hand, with the word “Invitation” written on it. The bar is elegantly decorated with dim lighting, cocktail glass on counter table, creating a sophisticated and intimate atmosphere. The city lights and rain outside the window create a reflective and moody ambiance. nega:behind, v-neckline, nsfw

Create a high-resolution, upper-body image of a cute anime girl with blue eyes and long, flowing gray hair. She has tanned skin and is an elf with delicately pointed ears. She is smiling warmly and looking directly at the viewer, giving a friendly and inviting expression. She is wearing a light, pastel-colored camisole that complements her complexion. Her hair cascades gracefully around her shoulders, with a few loose strands framing her face. The background should depict a sunny lakeside scene with clear blue skies, a sparkling lake, and lush greenery. Ensure the background is detailed yet softly blurred to keep the focus on the character. The style should be kawaii and highly detailed, capturing the charming and whimsical essence of anime art. Ensure the image is high quality and high resolution, with careful attention to the character’s features and expression.
