What you get
Google released version 3.0.0 of its Gen AI SDKs: @google/genai for JavaScript and TypeScript on November 6, 2026, and google-genai for Python (tagged November 5, published to PyPI early on November 6 UTC). Both are major releases with breaking changes.
In both SDKs:
- The default API version is now
v1, notv1beta, for the Gemini Developer API. Clients set up for Vertex AI keepv1beta1as their default. - Some model aliases don't exist on
v1. Google namesgemini-flash-latest,gemini-flash-lite-latestandgemini-pro-latest. They exist only onv1beta. - A new
GOOGLE_GENAI_API_VERSIONenvironment variable sets the API version when your code doesn't. A version set in code wins over it. - Interactions API:
CodeExecutionResultStep.resultis no longer just a string. It can now hold multimodal content. The JSON for text-only results is still a plain string, but typed code that reads it as a string has to check the type first. MALFORMED_RESPONSEis a newFinishReasonvalue.- The release notes list "Disable GenerateVideos for Gemini API".
JavaScript only: Node.js 22 or later is now required. Node.js 20 users should stay on @google/genai@^2.
Python only: the default HTTP client is now httpx2, and httpx is no longer installed by default. httpx2 uses the operating system's certificate store instead of certifi when SSL_CERT_FILE and SSL_CERT_DIR are not set.
