Inference Engine Support Status for Ling-3.0-flash

·2026.07.28 01:33

Key point

This summarizes the support plans and technical bottlenecks for the Ling-3.0-flash model across major inference engines.

Details

The support status of major inference engines for the recently released Ling-3.0-flash model is as follows.

  • SGLang: Promised Day-0 support, and is developing the model based on its identified KDA + MLA hybrid attention structure.
  • vLLM: Stated that support will be provided once the model weights are open-sourced.
  • llama.cpp: Currently experiencing the biggest bottleneck. The support request for the Bailing MoE variant structure adopted by this model was closed as 'not_planned'.

Technically, the delta-net/KDA kernel is already implemented, so the attention structure itself is not an issue, but a PR to implement the Bailing MoE conversion path is needed.
