Pydantic AI v2.18.0 adds AdvisorTool, Bedrock provider, multi-region support
agent-framework orchestration tool-use
Pydantic AI v2.18.0 is a quiet but useful release for teams actually shipping agents in production. The new BedrockMantleProvider gives AWS-native shops a cleaner path to running agents on Bedrock, AdvisorTool support lands on Anthropic and OpenRouter, and Google Cloud gets US/EU multi-region routing. No single feature is a breakthrough, but the pattern is clear: Pydantic AI is systematically closing the gaps across every major infrastructure stack, which matters more the further along you are in deployment.
Full analysis
Pydantic AI released v2.18.0 on July 24, 2026, adding several notable features for agent builders. Key additions include AdvisorTool support for Anthropic and OpenRouter models, a new BedrockMantleProvider for AWS Bedrock integration with normalized tool-call IDs, an external_web_access option to the WebSearchTool for OpenAI Responses API, and US/EU multi-region location support for Google Cloud Provider.
The AdvisorTool expansion broadens the framework's guidance/advisory tool pattern to two more major model providers, while the BedrockMantleProvider gives Pydantic AI agents a cleaner path to running on AWS infrastructure. Together, these changes signal continued cross-platform provider coverage for teams building production agents on top of Pydantic AI.
