Starting from [langchain
v0.0.322](https://github.com/langchain-ai/langchain/releases/tag/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.

```python
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)
```

## Response streaming

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

```python
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()
```

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

```python
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()
```
