UnverifiedAI Gateway is the unified entry point for model calls provided by Vercel, converging the APIs of multiple model providers such as OpenAI, Anthropic, Google, GLM, and Kimi into a single endpoint, and it handles routing, retries, caching, and usage statistics.77% similarUnverifiedAI infrastructure at the foundational layer includes specialized compute chips such as GPUs and TPUs as well as data centers; the middle layer includes distributed training frameworks (such as PyTorch and JAX), model inference engines (such as vLLM and TensorRT), and vector databases; and the upper layer includes MLOps platforms and more.77% similarUnverifiedThere are three mainstream technical approaches to solving integration fragmentation: using a middleware automation platform to connect tool APIs, adopting an AI agent platform with native integration capabilities, or selecting a hub tool to consolidate data.76% similarVerifiedConnectors serve as a bridge connecting AI programming assistants to external services, data sources, or tools.76% similarVerifiedThe topmost layer of the AI industry's hierarchical structure is the foundation model layer (e.g., the GPT series, LLaMA, DeepSeek), the middle layer is the framework and middleware layer (e.g., LangChain, vector databases), and the bottom layer is the application development layer, analogous to the IaaS-PaaS-SaaS architecture of the internet era.76% similar
