Qwen3.5 9B

NVIDIA
Qwen3.5-9B is a multimodal causal language model built with a 9B parameter architecture. It uses a 32-layer transformer with 16 attention heads, 4 KV heads, and a 4,096 hidden size, paired with a 12,288 intermediate dimension. The model supports a native 262K token context window, extendable to ~1M tokens, and includes a 27-layer vision encoder with 1,152 hidden size. It combines Gated DeltaNet and attention layers, delivering efficient long-context reasoning, strong multimodal performance, and broad multilingual coverage across 200+ languages.

Note

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