Artificial Analysis@ArtificialAnlys · XHiDream 发布 O1-Image-1.5，在 Artificial Analysis 文生图排行榜中位列第三，超越 Google Nano Banana 2。该闭源模型可生成高达 2K 分辨率图像，基于自研 Unified Transformer（UiT）架构，将原始像素、文本和任务条件编码到统一 token 空间。质量仅次于 OpenAI，与 GPT Image 1.5 (high)、Nano Banana 2（Gemini 3.1 Flash Image Preview）及 Cosmos3-Super-Text2Image 相当。定价 $80/千张，现可通过 HiHarness 及 Vivago 平台使用。
HiDream-O1-Image-1.5 lands at #3 on the Artificial Analysis Text to Image Leaderboard， surpassing Google's Nano Banana 2！
HiDream's latest addition to the O1 Image model series is a closed-source model capable of generating images up to 2K resolution from text prompts. The O1 Image family is built on HiDream's Unified Transformer （UiT）， which encodes raw pixels， text， and task conditions in a single shared token space rather than splitting the task across a separate text encoder， a VAE， and an image model.
On the Artificial Analysis Text to Image Arena， HiDream-O1-Image-1.5 places second only to OpenAI's image models， delivering quality similar to GPT Image 1.5 （high）， Nano Banana 2 （Gemini 3.1 Flash Image Preview）， and Cosmos3-Super-Text2Image.
HiDream-O1-Image-1.5 is priced at $80/1k images and is currently available on HiDream's HiHarness platform （accessible via their website）， as well as on the Vivago platform.
Congratulations to @HiDream_ai and @vivago_ai on the release！
