Observe (Tracing & Spans)
Trace what agents actually did with span, trace, and session-level observability powered by OpenInference and OpenTelemetry standards.
Evaluate (Evals Framework)
Run automated, scalable evaluations (span, trace, and session evals) to measure whether agents are improving or regressing.
Improve (Continual Learning & Testing)
Test prompts and harnesses faster and validate whether fixes improve agent performance before deploying to production, enabling a continual learning loop.
Alyx (AI Engineering Agent)
An in-app AI engineering agent that runs evals, debugs issues, and helps improve agents by suggesting fixes or running tests.
adb (Observability Datastore)
A scalable datastore for GenAI traces that stores agent trajectories and context in open formats and connects to BigQuery, Databricks, or Snowflake via DataFabric.
Phoenix (Open-source Observability & Evals)
A self-hostable, open-source tool to trace LLM calls, run evaluations, investigate failures, and keep control of data.
OpenInference Standards
Built on OpenInference semantic conventions (and OpenTelemetry) to provide interoperable, non-proprietary tracing formats for GenAI observability.
Agent-native Workflows & Integrations
Supports agent-first debugging and agent-native development across tooling such as Cursor, Claude Code, OpenCode and more.

Use Cases
Agent debugging and root-cause analysis
Trace agent executions and inspect spans, traces, and sessions to understand what happened inside each request and debug failures.
Automated evaluation and quality monitoring
Run scalable evals to measure agent performance over time and detect regressions or improvements in production.
Continuous improvement and prompt testing
Test prompts and harnesses, validate fixes, and close the continual learning loop to improve agent behavior before deploying changes.
Observability for generative AI applications
Support for chatbots, RAG systems, copilots, and agents to monitor production performance and improve model and workflow quality.
