Inside Opik
-
Opik feature (also available as an open-source SDK) that automatically iterates and tunes system prompts across seven optimization algorithms before freezing them for production.
-
Cost Intelligence Application
Opik feature that tracks and attributes AI/coding-agent token spend (Claude Code, Codex) across engineering teams, surfacing recoverable-spend opportunities.
-
AI debugging assistant built into Opik: investigates any logged trace, finds the root cause, reads your source files through opik connect, proposes code fixes for your approval, reruns your agent and adds the failing trace to a test suite to confirm the fix.
