Microsoft's managed cloud platform for accessing, fine-tuning, and deploying foundation models from OpenAI, Anthropic, Meta, and partner providers.
Azure AI Foundry is Microsoft's unified cloud platform for building with foundation models. It gives teams a single managed environment to access OpenAI and other frontier models, fine-tune them, build and deploy AI agents, and run production workloads, with enterprise guardrails, governance, and Azure networking built in.
As the direct cloud analog to Amazon Bedrock, it competes with multi-model gateways such as OpenRouter for teams that want provider-neutral model access without managing per-provider API keys, formats, and billing.
