Hy3

huggingface.co·Infrastructure

Hy3-GGUF is a quantized language model hosted on Hugging Face in GGUF format. It employs a custom tokenization scheme that defines numerous specialized tokens for structured interactions.

The model includes distinct tokens for sentence beginnings, padding, user and assistant roles, as well as tags for reasoning segments, tool call blocks, individual tool calls, argument keys and values, and tool responses. These tokens support formatted output such as reasoning tags and tool-related structures. The implementation appears in a template that generates these tokens dynamically using a placeholder variable.

It is provided as part of the Hugging Face ecosystem of models. The page belongs to the organization or user AngelSlim and sits within the platform's collection of foundation models intended for open-source use and local inference runners compatible with the GGUF format. Hugging Face positions its model repository as a means to advance artificial intelligence through open source and open science.

No pricing, licensing details, or specific end-user roles beyond the general model-hosting context are stated.
