Comet ML
Application
Opik feature that tracks and attributes AI/coding-agent token spend (Claude Code, Codex) across engineering teams, surfacing recoverable-spend opportunities.
AI agent
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.
Developer tool
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.
Comet's dataset- and model-versioning product for tracking artifacts and lineage from training through production.
Comet's experiment-tracking product for logging, comparing, visualizing and reproducing machine-learning training runs.
LangWatch
Application
A LangWatch component that evaluates stored agent conversations, traces, and LLM calls against questions expressed in plain language.
AI agent
LangWatch's automated AI engineer: it reads production traces, clusters failures, writes tests and opens a pull request with CI checks, running on the customer's own model keys; you review and merge.
Developer tool
LangWatch LLM observability traces model calls, tool calls and retrieval steps while displaying costs, latency and errors.
