Zhihu AI has officially released CogView4, its latest open-source text-to-image model. Boasting 600 million parameters, CogView4 notably supports both Chinese and English prompts and text-to-image generation, making it the first open-source model capable of generating Chinese characters within images. Its key feature is its support for bilingual prompts, excelling at understanding and following complex Chinese instructions, a boon for Chinese content creators. As the first open-source text-to-image model to generate Chinese characters in images, it fills a significant gap in the open-source landscape.
