These models natively support streaming, and as is the case with all LangChain LLMs they expose a batch method to handle concurrent requests, as well as async methods for invoke, stream, and batch. Below are a few examples. print(llm.batch(["What's 2*3?","What's 2*6?"])) ...
In computer science, asynchronous (async) functions are those that operate independently of other processes, thereby enabling several API requests to be run concurrently without waiting for each other. In LangChain, these async functions let you make many API requests all at once, not one after ...
