KAITO

KAITO (Kubernetes AI Toolchain Operator) is an open-source operator suite that automates LLM model inference, fine-tuning, and Retrieval Augmented Generation (RAG) engine deployment in Kubernetes clusters. It simplifies the process of deploying large AI models through optimized preset configurations and integrates with Karpenter for GPU node auto-provisioning.

KAITO publishes 4 APIs on the APIs.io network, including Chat API, Index Management API, Persistence API, and 1 more. Tagged areas include AI, GPU, Inference, Kubernetes, and LLM.

KAITO’s developer surface includes documentation, getting-started guide, and 5 more developer resources.
