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! See below for comparisons between HiDream-O1-Image-1.5 and other leading models in the Artificial Analysis Image Arena 🧵
