Klu (klu.ai) is an LLM app platform for designing, deploying, evaluating, and observing prompt-driven AI applications. The Klu Engine exposes a REST API at https://api.klu.ai/v1 (Bearer API key) where an Action encapsulates a prompt template, model config, context (RAG), and output parsing, and is invoked to generate completions, with data, feedback, sessions, and models managed alongside it. NOTE - product development appears dormant - the official klu SDK last shipped in March 2025 and the founding team's recent open-source work has shifted toward xAI / Grok tooling - see review.yml for the honest status assessment.
