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