Qwen3.5-VL¶

Class: Qwen35VLBlockV1

Source: inference.core.workflows.core_steps.models.foundation.qwen3_5vl.v1.Qwen35VLBlockV1

This workflow block runs Qwen3.5-VL—a vision language model that accepts an image and an optional text prompt—and returns a text answer based on a conversation template.

Type identifier¶

Use the following identifier in step "type" field: roboflow_core/qwen3_5vl@v1to add the block as as step in your workflow.

Properties¶

Name	Type	Description	Refs
`name`	`str`	Enter a unique identifier for this step..	❌
`prompt`	`str`	Optional text prompt to provide additional context to Qwen3.5-VL. Otherwise it will just be a default one, which may affect the desired model behavior..	❌
`model_version`	`str`	The Qwen3.5-VL model to be used for inference..	✅
`system_prompt`	`str`	Optional system prompt to provide additional context to Qwen3.5-VL..	❌
`enable_thinking`	`bool`	If true, enables Qwen3.5-VL's thinking mode, which allows the model to generate reasoning tokens before answering. The thinking output will be returned in the 'thinking' field..	❌
`max_new_tokens`	`int`	Maximum number of tokens to generate. If not set, the model's default will be used. Consider increasing for thinking mode..	❌

The Refs column marks possibility to parametrise the property with dynamic values available in workflow runtime. See Bindings for more info.
