Market and trust evidence

Edition not yet matched

No exact skills.sh identity match is available for this repository. Repository adoption and freshness remain visible above; install momentum is not inferred.

Trust analysis is a screening signal, not a security warranty. Read the ranking and trust methodology.

In practice

Written by AI from this repository’s README · medium confidence

LLM calls, retrievals and tool use do not map onto generic tracing conventions, so spans carry no useful detail.

Use it when

Use it when you want standard spans for LLM apps that any OpenTelemetry compatible backend can consume.

Not the right pick when

It is a monorepo of many per framework packages rather than one install, so you pick the instrumentations you need.

Capabilities

  • semantic conventions for tracing LLM applications
  • instrumentations for popular ML SDKs and frameworks
  • packages across Python, JavaScript, Java and Go
  • works with any OpenTelemetry compatible backend
  • specification kept in markdown in the spec directory

Cost: Free and open source

OpenInference is a set of conventions and plugins that is complimentary 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.

Instrumentation

OpenInference provides a set of instrumentations for popular machine learning SDKs and frameworks in a variety of

languages.
