Kong is an AI connectivity platform that secures, manages, and monetizes API and AI token traffic.
AI infrastructure is the stack of compute, data, and software that trains, serves, and scales AI models. It spans GPUs and orchestration like Ray, inference platforms like fal, vector and caching layers like Redis, and frameworks like the Vercel AI SDK. Teams assemble these pieces to move a model from prototype to production.
At minimum you need compute to serve the model, a way to manage requests and scaling, and storage for data and embeddings. Most teams add an inference layer, a vector store for retrieval, and monitoring. Ray handles distributed compute, fal serves generative models, and Redis stores embeddings and cache, with a framework tying them together.
Training infrastructure runs large batch compute jobs to build or fine-tune a model, demanding many GPUs and high-throughput data pipelines. Inference infrastructure serves the finished model to users in real time, optimizing for latency and cost per request. Ray supports both, while platforms like fal focus on fast inference.
Right-size the model, batch requests, and cache repeated results rather than recomputing them. Serving platforms like fal optimize GPU use, and a vector cache in Redis avoids re-running retrieval. Many teams also route simple queries to smaller models and reserve large models for hard cases.
A vector store holds embeddings, the numerical representations of text or images, so an application can find semantically similar content quickly. It powers retrieval-augmented generation, where a model pulls relevant context before answering. Redis and dedicated vector databases provide this layer between your data and the model.
Use managed platforms early, since they remove undifferentiated setup and let you ship faster. Build or self-host when scale, cost, data residency, or custom performance needs justify the engineering. Many teams start on hosted inference like fal and a framework like the Vercel AI SDK, then bring pieces in-house as usage grows.
