OpenAI GPT4 Lookup
Perform a lookup with GPT4 on objects in an ROI, or on a ROI in the frame.
Overview
The OpenAI GPT4 Lookup node is designed to perform lookups using the powerful GPT4 model on objects within a Region of Interest (ROI), or on a ROI within the frame. This functionality is useful for applications requiring advanced recognition and understanding of objects or areas within a video feed.

Properties
Property | Description | Type | Default | Required |
---|---|---|---|---|
roi_labels | Regions of interest labels | hidden | Yes | |
rois | Regions of interest. Type: polygon. Default: null. Conditional on roi_labels . | polygon | null | Yes |
processing_mode | Processing mode. Options: ROIs, at Interval (rois_interval), ROIs, upon Trigger (rois_trigger), Objects in an ROI (objects). | enum | rois_interval | Yes |
interval | Lookup interval. Collect objects or ROIs for lookup at least this many seconds apart. | float | 1 | No |
batch_size | Number of images to process in each GPT request. Set to more than 1 to use prompts that reference multiple images. | number | 1 | No |
trigger | Queue ROI for lookup when this condition evaluates to true. Conditional on processing_mode being rois_trigger . | trigger-condition | null | No |
enable_prebuffer | If true, samples ROI at interval to fill batch, and performs lookup when trigger is met. Else performs lookup when batch is full. Conditional on processing_mode being rois_trigger . | bool | false | No |
objects_to_process | Object types to process. ex. car ,person ,car.red . Conditional on processing_mode being objects . | model-label | null | No |

max_lookups_per_obj | Max. attempts per object. Conditional on processing_mode being objects . | number | 5 | No |
openai_api_key | OpenAI API Key | string | null | Yes |
prompt | GPT Prompt | text | null | Yes |
detail_level | GPT Detail Level. Options: Low, High. | enum | low | No |
max_tokens | Maximum number of tokens to return for each request. | number | 500 | No |
post_processing | GPT Results Post Processing. Options: Text, JSON. | enum | text | No |
post_proc_attribs_path | JSON path to extract object/ROI attributes from GPT response. ex. object_color . Conditional on post_processing being json . | string | null | No |
display_roi | Display ROI on video? | bool | true | No |
display_objinfo | Display results on video? Options: Disabled, Bottom left, Bottom right, Top left, Top right. | enum | bottom_left | No |
debug | Log debugging information? | bool | false | No |

nodes.[node_id].recognized_obj_delta | The change in the count of recognized objects. |
nodes.[node_id].label_changed_obj_delta | The change in the count of objects with changed labels. |
nodes.[node_id].unrecognized_obj_count | The count of unrecognized objects. |
nodes.[node_id].unrecognized_obj_delta | The change in the count of unrecognized objects. |
