Automatically intercepts and instruments calls to 30+ LLM providers (OpenAI, Anthropic, Google, Azure, local models) using the OpenTelemetry BaseInstrumentor pattern to patch third-party libraries at runtime. Captures prompts, completions, token usage, latency, costs, and model metadata without code changes, exporting structured traces and metrics via OTLP to any OpenTelemetry-compatible backend. Uses provider-specific wrapper implementations to normalize heterogeneous APIs into OpenTelemetry semantic conventions.
Unique: Uses OpenTelemetry-native instrumentation (BaseInstrumentor pattern) with provider-specific wrappers to normalize 30+ heterogeneous LLM APIs into semantic conventions, enabling single-line initialization (`openlit.init()`) without modifying application code. Captures both structured telemetry (traces/metrics) and unstructured payloads (prompts/completions) in a unified pipeline.
vs alternatives: More comprehensive than Langfuse or LangSmith because it instruments at the SDK level (OpenAI, Anthropic directly) rather than requiring framework integration, and exports to any OpenTelemetry backend instead of proprietary platforms.
Auto-instruments vector database clients (Qdrant, Chroma, Pinecone, Milvus, Astra, Weaviate) to capture embedding operations, retrieval queries, and vector similarity metrics. Tracks embedding model usage, vector dimensions, retrieval latency, and result cardinality as OpenTelemetry spans and metrics. Integrates with the LLM instrumentation pipeline to correlate RAG retrieval steps with downstream LLM calls for end-to-end observability.
Unique: Instruments vector databases at the client library level (Qdrant SDK, Chroma client, etc.) using the same BaseInstrumentor pattern as LLM providers, enabling automatic correlation between embedding operations and downstream LLM calls in RAG pipelines. Captures retrieval latency, result cardinality, and embedding model metadata in a unified telemetry pipeline.
vs alternatives: More integrated than standalone vector database monitoring tools because it correlates retrieval operations with LLM calls in the same trace, providing end-to-end RAG pipeline visibility without separate instrumentation.
Defines and implements OpenTelemetry semantic conventions for AI operations (LLM calls, embeddings, vector database queries, agent steps) that standardize attribute names, span types, and metric definitions across all SDKs and providers. Semantic conventions enable consistent telemetry collection across heterogeneous LLM providers and frameworks, allowing downstream tools to understand and correlate AI telemetry without provider-specific logic. Conventions are documented in the OpenTelemetry specification and implemented in all SDKs.
Unique: Implements OpenTelemetry semantic conventions for AI operations (LLM calls, embeddings, vector database queries, agent steps) that standardize attribute names and span types across all SDKs and providers. Enables consistent telemetry collection and downstream tool integration without provider-specific logic.
vs alternatives: More standardized than proprietary telemetry schemas because it uses OpenTelemetry semantic conventions, enabling interoperability with other OpenTelemetry tools and avoiding vendor lock-in to a single observability platform.
Implements W3C Trace Context propagation to correlate traces across multiple services and languages in distributed AI applications. Automatically injects trace context (trace ID, span ID, trace flags) into outgoing requests (HTTP, gRPC) and extracts trace context from incoming requests to maintain trace continuity. Enables end-to-end tracing of requests that span multiple microservices, including LLM calls, vector database queries, and application logic.
Unique: Implements W3C Trace Context propagation to automatically correlate traces across multiple services and languages in distributed AI applications. Injects and extracts trace context from HTTP/gRPC requests to maintain trace continuity without requiring manual trace ID management.

Provides a real-time dashboard that streams telemetry data (traces, metrics, logs) from the OpenTelemetry Collector to web clients via WebSocket or Server-Sent Events (SSE). Displays live LLM calls, token usage, latency, and costs as they occur without requiring page refresh. Dashboard includes filtering, search, and drill-down capabilities to explore telemetry in real-time. Enables developers to monitor LLM applications during development and debugging.

vs alternatives: More responsive than batch-based dashboards because it streams telemetry in real-time, enabling developers to see LLM behavior as it happens rather than waiting for batch processing and dashboard refresh cycles.
Provides batch evaluation capabilities to analyze historical LLM traces stored in the platform, including cost analysis, performance trends, prompt effectiveness, and policy compliance. Supports SQL-like queries on trace data to aggregate metrics by model, provider, user, or custom dimensions. Enables teams to identify optimization opportunities, track performance over time, and audit LLM usage for compliance.
Unique: Provides batch evaluation and historical analysis of LLM traces stored in the platform, enabling cost analysis, performance trends, and compliance auditing. Supports SQL-like queries on trace data to aggregate metrics by model, provider, user, or custom dimensions.
vs alternatives: More comprehensive than real-time dashboards because it enables historical trend analysis and compliance auditing, whereas real-time dashboards focus on current behavior and require manual aggregation for historical analysis.
Auto-instruments AI frameworks (LangChain, LangGraph, AutoGen, CrewAI) to capture framework-level operations: chain execution, tool calls, agent reasoning steps, and memory interactions. Instruments at the framework abstraction layer (e.g., LangChain's Runnable interface, LangGraph's StateGraph) to create hierarchical spans that represent the logical flow of AI applications. Automatically correlates framework operations with underlying LLM and vector database calls.
Unique: Instruments AI frameworks at the abstraction layer (LangChain Runnable interface, LangGraph StateGraph) rather than individual LLM calls, creating hierarchical spans that represent the logical flow of multi-step AI applications. Automatically correlates framework operations with underlying LLM, tool, and vector database calls in a single trace.
vs alternatives: More comprehensive than framework-specific logging because it integrates with OpenTelemetry standards and correlates with LLM/vector database telemetry, whereas LangChain's built-in callbacks are framework-specific and don't integrate with broader observability infrastructure.
Collects GPU metrics (utilization, memory usage, temperature, power consumption) from NVIDIA GPUs using the OpenTelemetry GPU Collector and exposes them as OpenTelemetry metrics. Integrates with the Python SDK to correlate GPU metrics with LLM inference operations, enabling visibility into hardware resource consumption during model serving. Supports Kubernetes environments via the OpenLIT Operator for automated GPU metric collection across clusters.
Unique: Integrates GPU metrics collection directly into the OpenLIT SDK using the OpenTelemetry GPU Collector, enabling automatic correlation between GPU resource consumption and LLM inference operations in the same trace. Supports Kubernetes environments via the OpenLIT Operator for cluster-wide GPU monitoring without manual instrumentation.
vs alternatives: More integrated than standalone GPU monitoring tools (nvidia-smi, DCGM) because it correlates GPU metrics with LLM inference telemetry in OpenTelemetry traces, providing unified visibility into hardware and application performance.
