| What makes it different | - Built by founders of OpenInference, the leading open standard for GenAI observability
- Signal surfaces what matters, uncovers root causes, and generates review-ready fixes automatically
- Processes 1 trillion spans and runs 1 billion evals per year at scale
- Flexible deployment with data staying under customer control
- Open-source-first approach with local-first option via Phoenix
| - 20x cheaper than cloud with self-hosted inference on consumer GPUs
- Kubernetes-native CRDs for Model and InferenceService, not wrappers around Kubernetes
- One operator supports seven pluggable runtime backends with no code changes
