Semantic governance policies support more model providers

Semantic governance policies support more model providers

Semantic governance policies now evaluate tool calls from agents that use models from providers other than Gemini. The policy engine reads each provider's request and response format, so the same policies apply whichever model your agent uses. Supported APIs include the Gemini Developer API and Gemini models on Gemini Enterprise Agent Platform, the Anthropic Messages API, Claude models on Gemini Enterprise Agent Platform, the OpenAI Chat Completions API, the Mistral AI API, the OpenAI-compatible endpoint on Gemini Enterprise Agent Platform (including Llama models), and self-hosted OpenAI-compatible servers such as vLLM. Streamed model responses aren't supported.

To govern these providers, update the when condition of your authorization policy to match each provider's request path. The updated condition also matches requests that include a query string.
