    Security, safety & abuse risks

    • Untrusted webpages, documents, and tool outputs can expose agents to prompt-injection attempts.
    • Broad tool permissions can amplify the consequences of incorrect or manipulated actions.
    • Software-engineering capabilities are dual-use and can support harmful development.

    Known flaws & limitations

    • The 200K-token context window limits the material available in an individual request.
    • The 64K-token maximum output limits the length of an individual response.
    • Published benchmark results depend on evaluation settings and do not guarantee equivalent production performance.
    • Generated code and tool actions require validation; strong benchmark performance does not establish correctness or security.

    Security advisories & risk updates

    No risk advisories logged since this profile started being tracked. New ones appear here automatically.

    What this means if you are building on it

    • Unsupervised actions involving production credentials, irreversible changes, or financial transfers.
    • High-stakes decisions without qualified human review.
    • Workloads requiring more than 200K tokens in one request or more than 64K output tokens.
    • Security-critical code deployment without testing and review.

    Everything here comes from published documentation, advisories and reporting, with links to the original sources. It is not a complete vulnerability database — always check the provider's own security notices before shipping.
