Google + Weaviate

Google offers a wide range of models for natural language processing and generation. Weaviate seamlessly integrates with Google AI Studio and Google Vertex AI APIs, allowing users to leverage Google's models directly from the Weaviate database.

These integrations empower developers to build sophisticated AI-driven applications with ease.

Integrations with Google​

Embedding integration illustration

Google's embedding models transform text data into high-dimensional vector representations, capturing semantic meaning and context.

Weaviate integrates with Google's embedding models to enable seamless vectorization of data. This integration allows users to perform semantic and hybrid search operations without the need for additional preprocessing or data transformation steps.

Generative AI models for RAG​

Single prompt RAG integration generates individual outputs per search result

Google's generative AI models can generate human-like text based on given prompts and contexts.

Weaviate's generative AI integration enables users to perform retrieval augmented generation (RAG) directly from the Weaviate database. This combines Weaviate's efficient storage and fast retrieval capabilities with Google's generative AI models to generate personalized and context-aware responses.

Summary​

These integrations enable developers to leverage Google's powerful models directly within Weaviate.

In turn, they simplify the process of building AI-driven applications to speed up your development process, so that you can focus on creating innovative solutions.

Credentials​

You must provide a valid Googles API credentials to Weaviate for these integrations.

Vertex AI​

Automatic token generation​
Added in

From Weaviate versions 1.24.16, 1.25.3 and 1.26.

Not available on Weaviate Cloud instances

This feature is not available on Weaviate cloud instances.

You can save your Google Vertex AI credentials and have Weaviate generate the necessary tokens for you. This enables use of IAM service accounts in private deployments that can hold Google credentials.

To do so:

  • Set USE_GOOGLE_AUTH environment variable to true.
  • Have the credentials available in one of the following locations.

Once appropriate credentials are found, Weaviate uses them to generate an access token and authenticates itself against Vertex AI. Upon token expiry, Weaviate generates a replacement access token.

In a containerized environment, you can mount the credentials file to the container. For example, you can mount the credentials file to the /etc/weaviate/ directory and set the GOOGLE_APPLICATION_CREDENTIALS environment variable to /etc/weaviate/google_credentials.json.

Search locations for Google Vertex AI credentials

Once USE_GOOGLE_AUTH is set to true, Weaviate will look for credentials in the following places, preferring the first location found:

  1. A JSON file whose path is specified by the GOOGLE_APPLICATION_CREDENTIALS environment variable. For workload identity federation, refer to this link on how to generate the JSON configuration file for on-prem/non-Google cloud platforms.
  2. A JSON file in a location known to the gcloud command-line tool. On Windows, this is %APPDATA%/gcloud/application_default_credentials.json. On other systems, $HOME/.config/gcloud/application_default_credentials.json.
  3. On Google App Engine standard first generation runtimes (<= Go 1.9) it uses the appengine.AccessToken function.
  4. On Google Compute Engine, Google App Engine standard second generation runtimes (>= Go 1.11), and Google App Engine flexible environment, it fetches credentials from the metadata server.

Get started​

Weaviate integrates with both Google AI Studio or Google Vertex AI.

Go to the relevant integration page to learn how to configure Weaviate with the Google models and start using them in your applications.
