Three models named "pumpkin"
Image generation models with hidden names, "pumpkinspice," "pumpkinpie" and "pumpkinvine," appeared on LM Arena, which compares AI models through user votes. @aitrackerbot, an X account that tracks new model releases, posted on Oct. 29 (Oct. 30 Japan time) that they appear to be the next model from China's HiDream. It speculated that they are successors to "HiDream-O1-Image," released in May.
No basis for the speculation was given, and ORIENS has not been able to confirm it. HiDream has not made an announcement.
The current model is May's "O1"
In May, HiDream released the weights of its image generation model "HiDream-O1-Image." It has 8 billion parameters and generates images with a single system that handles pixels directly, without using a component to read text or a component to compress images. It outputs images of up to 2048-by-2048 pixels, and the weights can be used under the MIT license.
It does not rank highly on evaluation platforms. It scored about 1115 points in LM Arena's text-to-image category and is not among the top models in comparisons by Artificial Analysis either. Its price of about $0.04 per image is on the cheaper side.
Testing on Arena has become common
Companies often test models with hidden names on Arena before release. Anonymous models believed to be from OpenAI were also found on Arena in October (related article).
