vision-fine-tuning

Grab uses OpenAI's GPT-4o vision fine-tuning to improve GrabMaps, achieving significant accuracy gains in speed limit sign localization (13%), lane counting (20%), and reducing manual mapping efforts across Southeast Asia's complex road networks.

OpenAI introduces vision fine-tuning capabilities for GPT-4o, allowing developers to customize the model with image data in addition to text for improved performance on vision tasks like visual search, object detection, and medical image analysis.
