openinference

OpenInference is a set of conventions and plugins that is complementary to OpenTelemetry to enable tracing of AI applications. OpenInference is natively supported by Arize Phoenix and Arize AX, but can be used with any OpenTelemetry-compatible backend as well.

Specification

The OpenInference specification is edited in markdown files found in the spec directory. It's designed to provide insight into the invocation of LLMs and the surrounding application context such as retrieval from vector stores and the usage of external tools such as search engines or APIs. The specification is transport and file-format agnostic, and is intended to be used in conjunction with other specifications such as JSON, ProtoBuf, and DataFrames.
