KubeAI is an AI inference operator for Kubernetes that simplifies serving machine learning models in production. It supports large language models via vLLM and Ollama, speech-to-text via FasterWhisper, vector embeddings via Infinity, and reranking with cross-encoder models. The system provides intelligent autoscaling from zero, model caching with dynamic adapters for LoRA, and an OpenAI-compatible API interface while requiring no external dependencies like Istio or Knative.
