    1313AI Search for WordPress enhances the search experience by:
    1414- Replacing the default WordPress search with an AI-powered intelligent search system.
    15 - Generating embeddings for posts using OpenAI’s `text-embedding-ada-002` model.
    16 - Contextualizing search queries for better relevance and precision.
     15- Generating embeddings for posts using OpenAI’s `text-embedding-3-small` model via an external Node.js service (Open AI account isn't necessary).
     16- Managing embeddings centrally with per-origin quota control.
     17- Caching results locally using WordPress transients.
    1718- Ranking posts based on similarity using cosine similarity metrics.

    23 - **Embeddings Table**: Stores AI-generated embeddings for all posts in the database.
    24 - **Admin Settings**: Easily configure the plugin via the WordPress admin panel.
    25 - **Seamless Integration**: Automatically updates embeddings when posts are saved or updated.
    26 - Cached results for better performance
     24- **Intelligent Search**: AI-powered context inference.
     25- **Remote Embedding Service**: Embeddings stored in a central MySQL database through a Node.js API.
     26- **Admin Settings**: Manage global token and service URL.
     27- **Bulk Embedding Generation**: Generate embeddings for multiple posts or custom post types.
     28- **Caching**: Local transient caching.

    4445### What is required to use AI Search for WordPress?
    45 You need an OpenAI API key to use this plugin. You can get one from the [OpenAI website](https://openai.com/).
     46If you want to use the service we provide: nothing. If you want to use your own Open AI key, you'll need that.
    4647
    4748### How does this plugin work?
    48 The plugin uses OpenAI’s `text-embedding-ada-002` model to generate embeddings for your posts. When users search, it matches the query embedding with post embeddings in the database for more relevant results.
     49The plugin uses OpenAI’s `text-embedding-3-small` model to generate embeddings for your content. When users search, it matches the query embedding with post embeddings in the database for more relevant results.

    5354== External Service ==
    5455
    55 This plugin connects with Completions API from Open AI to get the embedding of the products. It also connects to the Embeddings endpoint.
     56This plugin connects with:
     57
     58- OpenAI Embeddings API: https://platform.openai.com/docs/guides/embeddings
     59- Custom Node.js Embedding Service
