Moondream2¶
Class: Moondream2BlockV1
Source: inference.core.workflows.core_steps.models.foundation.moondream2.v1.Moondream2BlockV1
This workflow block runs Moondream2, a multimodal vision-language model. You can use this block to run zero-shot object detection.
Type identifier¶
Use the following identifier in step "type" field: roboflow_core/moondream2@v1to add the block as
as step in your workflow.
