Logging with attachments

You can now upload, download, and contextually view attachments in Braintrust, expanding the capabilities of AI applications that accept and generate images, audio, video, and more. This feature allows users to log various types of binary attachments, including images, audio files, videos, and PDFs, which can be securely stored and accessed by the uploading user's organization. The attachment feature simplifies debugging and provides observability for multimodal and complex applications, enabling users to view and download attachments in the Braintrust UI.
