Opik SDK Reference

Opik is an open-source LLM observability platform. This skill covers the SDK: tracing, integrations, span types, and how to instrument code.

Core Concepts

A trace is a complete execution path (one user request → one response). Spans are individual operations within a trace, forming a hierarchy.

Type	Use For	Example
`general`	Custom operations, orchestration	Data processing, agent entry point
`llm`	LLM API calls	OpenAI completion, Anthropic message
`tool`	Tool/function execution, data retrieval	Web search, vector DB query, calculator
`guardrail`	Safety/validation checks	PII detection, content moderation
