Highlights
- Hosted on Hugging Face under the account k2021211255 as Aster-JEV-27B.
- Chat template renders image and video content blocks alongside text.
- Tool calls are emitted as <tool_call> blocks with <function=...> and <parameter=...> tags.
- Reasoning effort accepts xhigh (default), medium, or low; other values raise an exception.
- Uses <|endoftext|> as the padding token.
Questions about this entry
Short answers drawn from the linked project or page.
It is a model repository published on Hugging Face under the account k2021211255. The material available shows a chat template that handles text, image, and video content, renders tool definitions, and supports configurable reasoning effort.
The repository is hosted on Hugging Face. The material available for this entry shows model files and a chat template but no loading or serving instructions, so consult the model card on Hugging Face for runtime details.
Yes. The chat template renders available functions inside a <tools> block as JSON and instructs the model to reply with calls in the form <tool_call><function=name><parameter=key>value</parameter></function></tool_call>.
The template accepts xhigh, medium, and low, with xhigh as the default. Passing any other value raises an exception. Thinking can also be disabled through the enable_thinking flag.
The chat template renders image content as <|vision_start|><|image_pad|><|vision_end|> and video content with a video pad token. System messages are not allowed to contain images or videos.
No license is stated in the material available for this entry. Check the model page on Hugging Face for the license and any usage terms attached to the repository.
