Feature updates
Gemini and Vertex AI model support for Prompts
You can now configure Prompts to use Gemini and Vertex AI models. For more information, see Model provider API keys.
Added OpenAI o3-mini model to Prompts
When you add an OpenAI key to Prompts, you will now see the o3-mini model available in the Base Model drop-down menu. For a list of all available models, see Supported base models.
Display the prediction score in the labeling interface
When you have annotations generated by predictions (pre-annotations), you will now see the prediction score (also known as the "confidence score") under the model name in the labeling interface tabs.
Updated template images
The thumbnail images for the pre-built templates have been redesigned.
Clearer description of annotation count
The annotation counter at the bottom of the Data Manager has been updated to read "Submitted Annotations." It previously read "Annotations," which could cause confusion.
Region number in Relations panel
The Relations panel now displays the number identifier for the region when viewing relations between regions.
Improved readability for relation values
If you are using <Relation> tags in your labeling config, you can specify a value describing the relationship between regions.
In the past, it could be difficult to read these values when there were several overlapping relations and regions. With this release, the text value for the relationship is pulled forward into focus when you hover.
Security
Security enhancements and optimizations.
