"# Async API for LLM\n",
"\n",
"LangChain provides async support for LLMs by leveraging the [asyncio](https://docs.python.org/3/library/asyncio.html) library.\n",
"\n",
2023-03-02 05:55:43 +00:00
"Async support is particularly useful for calling multiple LLMs concurrently, as these calls are network-bound. Currently, only `OpenAI` `OpenAIChat`, and `PromptLayerOpenAI` are supported, but async support for other LLMs is on the roadmap.\n",
2023-02-08 05:21:57 +00:00
"\n",
"You can use the `agenerate` method to call an OpenAI LLM asynchronously."
