WhyLabs

WhyLabs was an AI observability platform that enabled teams to monitor and manage ML models and generative AI applications in production. Its AI Control Center assessed data in real-time from user prompts, RAG context, LLM responses, and application metadata to surface potential threats and data quality issues. The platform reduced manual operations by over 80% and cut time-to-resolution of AI incidents by 20x. WhyLabs open-sourced its full platform in 2025 following acquisition by Apple, contributing whylogs (privacy-preserving data logging) and LangKit (LLM monitoring toolkit) to the AI community.
