Generative Language API v1 - Package cloud.google.com/go/ai/generativelanguage/apiv1 (v0.3.4)

Package generativelanguage is an auto-generated package for the Generative Language API.

The Gemini API allows developers to build generative AI applications using Gemini models. Gemini is our most capable model in the world, built from the ground up to be multimodal. It can generalize and seamlessly understand, operate across, and combine different types of information. You can use the Gemini API for use cases like reasoning across text and images, content generation, dialogue agents, summarization and classification systems, and more.

NOTE: This package is in beta. It is not stable, and may be subject to changes.

General documentation

For information that is relevant for all client libraries please reference https://pkg.go.dev/cloud.google.com/go#pkg-overview. Some information on this page includes:

Example usage

To get started with this package, create a client.

ctx := context.Background()
// This snippet has been automatically generated and should be regarded as a code template only.
// It will require modifications to work:
// - It may require correct/in-range values for request initialization.
// - It may require specifying regional endpoints when creating the service client as shown in:
//   https://pkg.go.dev/cloud.google.com/go#hdr-Client_Options
c, err := generativelanguage.NewGenerativeClient(ctx)
if err != nil {
    // TODO: Handle error.
}
defer c.Close()

The client will use your default application credentials. Clients should be reused instead of created as needed. The methods of Client are safe for concurrent use by multiple goroutines. The returned client must be Closed when it is done being used.

Using the Client

The following is an example of making an API call with the newly created client.

ctx := context.Background()
// This snippet has been automatically generated and should be regarded as a code template only.
// It will require modifications to work:
// - It may require correct/in-range values for request initialization.
// - It may require specifying regional endpoints when creating the service client as shown in:
//   https://pkg.go.dev/cloud.google.com/go#hdr-Client_Options
c, err := generativelanguage.NewGenerativeClient(ctx)
if err != nil {
    // TODO: Handle error.
}
defer c.Close()

req := &generativelanguagepb.BatchEmbedContentsRequest{
    // TODO: Fill request struct fields.
    // See https://pkg.go.dev/cloud.google.com/go/ai/generativelanguage/apiv1/generativelanguagepb#BatchEmbedContentsRequest.
}
resp, err := c.BatchEmbedContents(ctx, req)
if err != nil {
    // TODO: Handle error.
}
// TODO: Use resp.
_ = resp

Use of Context

The ctx passed to NewGenerativeClient is used for authentication requests and for creating the underlying connection, but is not used for subsequent calls. Individual methods on the client use the ctx given to them.

To close the open connection, use the Close() method.

Functions

func DefaultAuthScopes

func DefaultAuthScopes() []string

DefaultAuthScopes reports the default set of authentication scopes to use with this package.

GenerativeCallOptions

type GenerativeCallOptions struct {
	GenerateContent       []gax.CallOption

	CountTokens           []gax.CallOption
	CancelOperation       []gax.CallOption
	GetOperation          []gax.CallOption
	ListOperations        []gax.CallOption
}

GenerativeCallOptions contains the retry settings for each method of GenerativeClient.

	// The call options for this service.
	CallOptions *GenerativeCallOptions

}

GenerativeClient is a client for interacting with Generative Language API. Methods, except Close, may be called concurrently. However, fields must not be modified concurrently with method calls.

OperationIterator manages a stream of *longrunningpb.Operation.

func (*OperationIterator) Next

Next returns the next result. Its second return value is iterator.Done if there are no more results. Once Next returns Done, all subsequent calls will return Done.

func (*OperationIterator) PageInfo

func (it *OperationIterator) PageInfo() *iterator.PageInfo

PageInfo supports pagination. See the google.golang.org/api/iterator package for details.
