Multi-LLM gateway architecture with Azure OpenAI, OpenAI, Anthropic, Google AI, and local Ollama providers unified through LiteLLM/PortKey routing and budget control. VS Code, CLI, and AI Agents connect to a centralized AI Gateway that intelligently routes requests, enforces spending limits, and logs all interactions across heterogeneous LLM endpoints. This pattern decouples application code from provider-specific APIs, enabling cost optimization, failover resilience, and vendor flexibility without rewriting integrations. Fork and customize this diagram on Diagrams.so to match your multi-cloud LLM strategy, then embed it in architecture docs or runbooks. Budget Control and Logging components ensure governance and observability critical for production AI workloads.
