Microsoft.Extensions.AI Vectorizer

RedisVL.Vectorizers.ExtensionsAI provides ExtensionsAiTextVectorizer, an IBatchTextVectorizer adapter over IEmbeddingGenerator<string, Embedding<float>> from Microsoft.Extensions.AI.

Package contents

  • ExtensionsAiTextVectorizer for adapting a Microsoft.Extensions.AI embedding generator to RedisVL vectorizer contracts

  • ExtensionsAiVectorizerOptions for forwarding optional embedding-generation settings

  • ExtensionsAiVectorizerPackage as the package marker type

Constructor options

Use this construction path:

  • new ExtensionsAiTextVectorizer(IEmbeddingGenerator<string, Embedding<float>> generator, ExtensionsAiVectorizerOptions? options = null)

ExtensionsAiVectorizerOptions currently supports:

  • GenerationOptions to forward EmbeddingGenerationOptions to the wrapped generator

  • DisposeGenerator when the adapter should own and dispose the wrapped generator

Interop workflow

This adapter keeps Microsoft.Extensions.AI outside the core RedisVL package while still letting applications reuse an existing embedding stack.

Typical usage is:

  • resolve or construct an IEmbeddingGenerator<string, Embedding<float>>

  • wrap it with ExtensionsAiTextVectorizer

  • pass the adapter anywhere RedisVL expects an ITextVectorizer or IBatchTextVectorizer

Example workflow

/examples/ExtensionsAiVectorizerExample shows the adapter pattern with OpenAI:

  • create an OpenAI.Embeddings.EmbeddingClient

  • convert it to IEmbeddingGenerator<string, Embedding<float>> with AsIEmbeddingGenerator(…​)

  • wrap it with ExtensionsAiTextVectorizer

  • vectorize one input and a batch of inputs through the RedisVL abstraction

Run it from the repository root:

dotnet run --project examples/ExtensionsAiVectorizerExample/ExtensionsAiVectorizerExample.csproj
