/**
 * Wrapper around Fireworks API for large language models fine-tuned for chat
 *
 * Fireworks API is compatible to the OpenAI API with some limitations described in
 * https://readme.fireworks.ai/docs/openai-compatibility.
 *
 * To use, you should have the `openai` package installed and
 * the `FIREWORKS_API_KEY` environment variable set.
 * @example
 * ```typescript
 * const model = new ChatFireworks({
 *   temperature: 0.9,
 *   apiKey: "YOUR-API-KEY",
 * });
 *
 * const response = await model.invoke("Hello, how are you?");
 * console.log(response);
 * ```
