Qwen3.5 27B

NVIDIA
Qwen3.5 27B is a large multimodal causal language model built with a 27B parameter architecture. It uses a 64-layer transformer with 24 attention heads, 4 KV heads, and a 5,120 hidden size, paired with a 17,408 intermediate dimension. The model supports a native 262K token context window, extendable to ~1M tokens, and integrates a 27-layer vision encoder with 1,152 hidden size. It combines Gated DeltaNet and attention layers, enabling efficient long-context reasoning, strong multimodal performance, and broad multilingual support across 200+ languages.

Note

Model is served in multimodal mode by default; to restrict the engine to text-only processing, use the --language-only flag.

Model Benchmarks

Each model was tested with a fixed input size and total token volume while increasing concurrency to measure serving performance under load.
