After the download, you have to make one include require_once('vendor/autoload.php');. After that you have to import the classes with use statements.

Example:
If you use only one package a project is not needed. But if you use more then one package, without a project it is not possible to import the classes with use statements.

In general, it is recommended to use always a project to download your libraries. In an application normally there is more than one library needed.
Some PHP packages are not free to download and because of that hosted in private repositories. In this case some credentials are needed to access such packages. Please use the auth.json textarea to insert credentials, if a package is coming from a private repository. You can look here for more information.

  • Some hosting areas are not accessible by a terminal or SSH. Then it is not possible to use Composer.
  • To use Composer is sometimes complicated. Especially for beginners.
  • Composer needs much resources. Sometimes they are not available on a simple webspace.
  • If you are using private repositories you don't need to share your credentials. You can set up everything on our site and then you provide a simple download link to your team member.
  • Simplify your Composer build process. Use our own command line tool to download the vendor folder as binary. This makes your build process faster and you don't need to expose your credentials for private repositories.

📄 Example: Text Classification with Arrays or Enums

Brain::classify simplifies the categorization of text. You can classify text using either an array of options or an Enum class.

Array Classification

Pass a list of categories as an array to classify your text.

This method evaluates 'banana' and categorizes it as one of the provided options.

Enum Classification

For structured categorization, use an Enum class.

Here, 'banana' is classified into the most fitting Enum category.

📄 Example: Generating a Vector Embedding

This method returns a vector embedding of the input, or a list of vector embeddings if you pass an array or a collection.

Changing the Base URL to use Together.AI, Mistral.AI, Perplexity.AI or other compatible API

You can change the base URL to use other compatible APIs by using the usingTogetherAI, usingMistralAI or usingPerplexity methods.

Or you can set the base URL directly, note that the API must be compatible with OpenAI's API, specifically the Chat completion endpoints.

Also note that JSON Mode (as used by Brain::json, Brain::classify, Brain::embedding and Brain::list) is not supported by all APIs.
