Langchain improvements: async and streaming

Langchain improvements: async and streaming

Starting from langchain v0.0.322 you can make efficient async generation and streaming tokens with deepinfra.

Async generation

The deepinfra wrapper now supports native async calls, so you can expect more performance (no more threads per invocation) from your async pipelines.

from langchain.llms.deepinfra import DeepInfra

async def async_predict():
    llm = DeepInfra(model_id="meta-llama/Llama-2-7b-chat-hf")
    output = await llm.apredict("What is 2 + 2?")
    print(output)
copy

Response streaming

Streaming lets you receive each token of the response as it gets generated. This is indispensable in user-facing applications.

def streaming():
    llm = DeepInfra(model_id="meta-llama/Llama-2-7b-chat-hf")
    for chunk in llm.stream("[INST] Hello [/INST] "):
        print(chunk, end='', flush=True)
    print()
copy

You can also use the asynchronous streaming API, natively implemented underneath.

async def async_streaming():
    llm = DeepInfra(model_id="meta-llama/Llama-2-7b-chat-hf")
    async for chunk in llm.astream("[INST] Hello [/INST] "):
        print(chunk, end='', flush=True)
    print()
copy
