Qwen3.5-27B-FlashHead
Optimized version of Qwen/Qwen3.5-27B using FlashHead, Embedl's efficient replacement for the language model head.
This model adds FlashHead, a lightweight replacement for the dense LM head that significantly improves throughput while preserving accuracy. Weights are kept in FP16 precision.
The model preserves Text + Image / Video -> Text behavior and reasoning capabilities while improving inference throughput.
FlashHead is available as a vLLM plugin via pip install flash-head.
