qwen3_5_vl

Model type	qwen3_5_vl
Class	Qwen35VL3ModelCausalLMModel
Task	hybrid-qwen-vl
Source	models/qwen35.py

Description

Qwen3.5-VL vision-language model (3-model split).

Builds three separate ONNX models for onnxruntime-genai:

• decoder: text decoder taking inputs_embeds (interleaved MRoPE)

• vision_encoder: packed-attention ViT outputting merged features

• embedding: token embedding + image feature fusion

The vision encoder is identical to Qwen3-VL’s

class:

Qwen3VLVisionModel. The text decoder uses

class:

Qwen35TextModel (hybrid linear/full attention).

Usage

mobius build --model <MODEL_ID> output_dir/

from mobius import build

model = build("<MODEL_ID>")
