OpenInference Instrumenter

OpenInference is an open-source set of OpenTelemetry-complementary semantic conventions, instrumentation libraries, and plugins for tracing AI applications. Its specification models LLM invocations and surrounding context such as vector-store retrieval and external tool use in a transport- and file-format-agnostic schema, while its instrumentations normalize traces from model, agent, and application frameworks across Python, JavaScript, Java, and Go. The project also defines conventions for real-time audio and voice-agent traces, allowing audio, transcripts, and tool calls to be represented in a queryable session trace. It is natively supported by Arize Phoenix and Arize AX and can send data to any OpenTelemetry-compatible backend.

An agent framework used by the Wonder Toys application. It includes OpenInference instrumentation for sending application traces to an observability system.

Arize AX is an AI engineering platform from Arize AI for observing and evaluating AI agents, including voice agents. It provides a unified session and trace view that combines audio, transcripts, latency metrics, tool calls, and evaluation results, allowing failures such as dead air, interruptions, transcription errors, and incorrect tool actions to be investigated together. The platform supports tracing real-time audio with OpenInference semantic conventions, audio-native evaluations for factors such as sentiment, latency, interruptions, and task success, and agent experiments that test fixes against failed traces. It is available through the Arize AX product interface and a terminal-based setup.

Open Interpreter is a command-line coding agent optimized for open and low-cost models. It is a fork of OpenAI's Codex focused on emulating provider-specific agent harnesses; its Rust-native harnesses can be switched with `/harness`, while providers and models can be changed from its terminal interface. It supports native sandboxing on macOS, Linux, and Windows, MCP, skills, hooks, permissions, AGENTS.md instructions, and local configuration and session state under `~/.openinterpreter`. The agent can run as an Agent Client Protocol agent for compatible editors, speak the Codex exec protocol, and provide a one-line binary override for applications using the Codex SDK. Its built-in QA skill can test web applications through a real browser and native applications through trycua. The project is distributed for macOS, Linux, and Windows through shell or PowerShell installation commands and uses shared agent directories and protocols where available.

OpenTelemetry is an open-source, vendor-neutral observability framework for cloud-native software. It provides APIs, SDKs, automatic-instrumentation agents, and collector services for capturing distributed traces, metrics, logs, and contextual metadata such as baggage. Its context-propagation mechanism correlates telemetry across service boundaries and carries trace identity through an application’s request path, including standard HTTP communication. The OpenTelemetry Collector receives, processes, filters, and routes telemetry to observability backends such as Jaeger, Prometheus, commercial systems, or custom solutions. It supports native SDKs for more than 12 languages and is hosted as a graduated project by the Cloud Native Computing Foundation.
