/**
 * TogetherAI chat model integration.
 *
 * The TogetherAI API is compatible to the OpenAI API with some limitations. View the
 * full API ref at:
 * @link {https://docs.together.ai/reference/chat-completions}
 *
 * Setup:
 * Install `@langchain/community` and set an environment variable named `TOGETHER_AI_API_KEY`.
 *
 * ```bash
 * npm install @langchain/community
 * export TOGETHER_AI_API_KEY="your-api-key"
 * ```
 *
 * ## [Constructor args](https://api.js.langchain.com/classes/_langchain_community.chat_models_togetherai.ChatTogetherAI.html#constructor)
 *
 * ## [Runtime args](https://api.js.langchain.com/interfaces/_langchain_community.chat_models_togetherai.ChatTogetherAICallOptions.html)
 *
 * Runtime args can be passed as the second argument to any of the base runnable methods `.invoke`. `.stream`, `.batch`, etc.
 * They can also be passed via `.bind`, or the second arg in `.bindTools`, like shown in the examples below:
 *
 * ```typescript
 * // When calling `.bind`, call options should be passed via the first argument
 * const llmWithArgsBound = llm.bind({
 *   stop: ["\n"],
 *   tools: [...],
 * });
 *
 * // When calling `.bindTools`, call options should be passed via the second argument
 * const llmWithTools = llm.bindTools(
 *   [...],
 *   {
 *     tool_choice: "auto",
 *   }
 * );
 * ```
