Catalogue only

This model is catalogued for reference. It is not hosted on LLM EU yet, and no first-party endpoint serves it here. Requests to it go to the provider directly, under that provider's own terms.

Summary

Hunyuan Hy3 is published by Tencent as open weights with 298.8B parameters under Apache-2.0. It takes text and returns text. The published configuration records no context window, so this card carries none. It is a base checkpoint without instruction tuning. The card is catalogue-only: LLM EU does not run this model. The publisher lists 1 language.

    When to use it

    Strengths

    • open weights are published on Hugging Face and can be downloaded without a vendor agreement
    • Apache-2.0 licence, so commercial self-hosting is permitted without a separate agreement

    Limits

    • catalogue only — LLM EU does not run this model, and nothing on this card implies an LLM EU endpoint
    • no evaluation has been run by LLM EU
    • the published configuration records no context window, so the card carries none
    • at 298.8B parameters, self-hosting needs multiple high-memory accelerators
