/**
|
|
* Creates a new instance of a language model (LLM) for chat interactions.
|
|
*
|
|
* @param {Object} options - The options for creating the LLM.
|
|
* @param {ModelOptions} options.modelOptions - The options specific to the model, including modelName, temperature, presence_penalty, frequency_penalty, and other model-related settings.
|
|
* @param {ConfigOptions} options.configOptions - Configuration options for the API requests, including proxy settings and custom headers.
|
|
* @param {Callbacks} [options.callbacks] - Callback functions for managing the lifecycle of the LLM, including token buffers, context, and initial message count.
|
|
* @param {boolean} [options.streaming=false] - Determines if the LLM should operate in streaming mode.
|
|
* @param {string} options.openAIApiKey - The API key for OpenAI, used for authentication.
|
|
* @param {AzureOptions} [options.azure={}] - Optional Azure-specific configurations. If provided, Azure configurations take precedence over OpenAI configurations.
|
|
*
|
|
* @returns {ChatOpenAI} An instance of the ChatOpenAI class, configured with the provided options.
|
|
*
|
|
* @example
|
|
* const llm = createLLM({
|
|
* modelOptions: { modelName: 'gpt-4o-mini', temperature: 0.2 },
|
|
* configOptions: { basePath: 'https://example.api/path' },
|
|
* callbacks: { onMessage: handleMessage },
|
|
* openAIApiKey: 'your-api-key'
