Only some models support tool use at the moment and so would like an update for when Opus 5.5 has it enabled.

    There is no published date for when claude-opus-5-5 web search or broader tool use will be enabled specifically via a Foundry API key.

    What is currently documented:

    • claude-opus-5-5 is available in Microsoft Foundry as Hosted on Azure and Hosted on Anthropic infrastructure.
    • Claude models support tool use features, including web search.
    • For Hosted on Azure deployments, only the web_search_20250305 tool version is supported.
    • Microsoft documentation does not provide a rollout date tied to claude-opus-5-5 and Foundry API key access.
    • Similar Microsoft Q&A responses state that when a web search feature is not yet available in Azure, Microsoft has not published an ETA and updates are announced through official release documentation.

    So the current answer is: claude-opus-5-5 has documented Claude tool capabilities, but no official availability date is published for web search enablement through the Foundry API key path.
