VLM as Classifier

v2

Class: VLMAsClassifierBlockV2 (there are multiple versions of this block)

Source: inference.core.workflows.core_steps.formatters.vlm_as_classifier.v2.VLMAsClassifierBlockV2

Warning: This block has multiple versions. Please refer to the specific version for details. You can learn more about how versions work here: Versioning

The block expects string input that would be produced by blocks exposing Large Language Models (LLMs) and Visual Language Models (VLMs). Input is parsed to classification prediction and returned as block output.

Accepted formats:

  • valid JSON strings

  • JSON documents wrapped with Markdown tags (very common for GPT responses)

Example: 

{"my": "json"}

Details regarding block behavior:

  • error_status is set True whenever parsing cannot be completed

  • in case of multiple markdown blocks with raw JSON content - only first will be parsed

Type identifier

Use the following identifier in step "type" field: roboflow_core/vlm_as_classifier@v2to add the block as as step in your workflow.

Properties

Name Type Description Refs
name str Enter a unique identifier for this step.. ❌
classes List[str] List of all classes used by the model, required to generate mapping between class name and class id.. ✅

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