Package dev.braintrust.trace

Class Base64Attachment

java.lang.Object

dev.braintrust.trace.Base64Attachment

public class Base64Attachment
extends Object

Utility to serialize LLM attachment data in a braintrust-friendly manner.

Users of the SDK likely don't need to use this utility directly because instrumentation will properly serialize messages out of the box.

The serialized json will conform to the otel input/output GenericPart schema. See https://opentelemetry.io/docs/specs/semconv/gen-ai/gen-ai-input-messages.json and https://opentelemetry.io/docs/specs/semconv/gen-ai/gen-ai-output-messages.json
