OpenInference is a set of conventions and plugins that is complimentary to [OpenTelemetry](https://opentelemetry.io/) to
enable tracing of AI applications. OpenInference is natively supported
by [Arize Phoenix](https://github.com/Arize-ai/phoenix) and [Arize AX](https://arize.com/docs/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](./spec/). 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.

## Instrumentation

OpenI
