MiniMax officially open-sources the H3 raw image model, producing 16.8 million pixels in 6 steps

MiniMax officially released H3-Image and open-sourced the model weights. This model can directly generate images of 4096×4096, approximately 16.8 million pixels, without additional upscaling. According to official data, the generation time is less than 10 seconds, with speeds reaching up to 5 times that of mainstream products. Text-to-image and image editing have been integrated into the same model, supporting up to 16 reference images.H3-Image follows the architecture of the H3 video model, removing the audio component while retaining the original text encoder and redesigning the decoder for images. The core image generation network has 33.1 billion parameters, requiring only 6 sampling steps to generate an image. On August 7, MiniMax researcher Kiro revealed in a Reddit AMA that the team is developing a dedicated image model based on the H3 homogenous architecture and plans to open-source the weights. They also proposed a workflow where the image model generates the first frame, which is then handed over to H3 for video generation.On November 3, Pruna AI launched P-H3-Image based on the open-source H3 video model, supporting raw images and retouching, compressing the generation network from 33.1 billion to approximately 20 billion parameters, requiring only 8 sampling steps. The minimal quantization version is about 20 GB, with peak memory usage of approximately 21 GB when generating 8 million pixel images. The official MiniMax version retains the 33.1 billion parameter generation network, with a sampling step count of 6, and supports higher resolutions and more reference images, with the original weights plus the reused text encoder totaling approximately 135 GB. There are regional restrictions on the open-source license; the United States, United Kingdom, European Union, and South Korea are not within the community license authorization regions. Companies with annual revenues exceeding 1 million dollars or those providing model hosting services to third parties must obtain separate authorization in advance.

first_img Baidu launched the model trading platform Ciyuan, gathering 42 large models

According to "Du Jia," Baidu recently launched an open model service platform called "Word Element Institute" aimed at developers, enterprise clients, and model suppliers. It is positioned as a matchmaking trading platform connecting model suppliers and consumers, gathering 42 large models, covering text and video models such as DeepSeek, Kimi, and Zhipu GLM. Developers can connect to the Word Element Institute API once to switch between models from multiple vendors and be billed based on usage.The same model can be accessed by multiple suppliers. The platform displays pricing, initial token latency, throughput speed, 7-day success rate, and historical call volume, and supports both OpenAI and Anthropic protocols. Taking DeepSeek-v4.1-flash as an example, the platform connects to 6 suppliers, marking the price savings ratio on the page, while also displaying context window, launch time, deployment region, and supplier credit evaluation.The platform ranking is based on real call data and can be viewed for the last 24 hours, last 7 days, and last 30 days. Screenshots show a total of 398 million calls in the last 7 days, with a total token volume of 51.336 trillion, involving 68 ranked model resources, and an average initial token latency of 290 milliseconds. DeepSeek-v4.1-flash ranks first in both call volume and token usage. Participating suppliers include Bochuan Technology, Infinite Mind, Star Hub Word Element, and Zhipu Original Factory, with the platform showcasing resources and supplier information through credit evaluations and blockchain proof.
