# Together AI 集成

> 使用 LangChain Python 集成 Together AI。

[Together AI](https://www.together.ai/) 提供了一个 API，可在几行代码内查询 [50+ 个领先的开源模型](https://docs.together.ai/docs/inference-models) 。

这段示例说明如何使用 LangChain 与 Together AI 模型交互。

## 安装

```python theme={null}
pip install -U langchain-together
```

## 环境

要使用 Together AI，您需要找到 API 密钥（位置：[api.together.ai/settings/api-keys](https://api.together.ai/settings/api-keys)）。该密钥可通过初始化参数 `together_api_key` 或设置环境变量 `TOGETHER_API_KEY` 传入。

## 示例

```python theme={null}
# Querying chat models with Together AI

from langchain_together import ChatTogether

# choose from our 50+ models here: https://docs.together.ai/docs/inference-models
chat = ChatTogether(
    # together_api_key="YOUR_API_KEY",
    model="meta-llama/Llama-3-70b-chat-hf",
)

# stream the response back from the model
stream = chat.stream_events("Tell me fun things to do in NYC", version="v3")
for token in stream.text:
    print(token, end="", flush=True)

# if you don't want to do streaming, you can use the invoke method
# chat.invoke("Tell me fun things to do in NYC")
```

```python theme={null}
# Querying code and language models with Together AI

from langchain_together import Together

llm = Together(
    model="codellama/CodeLlama-70b-Python-hf",
    # together_api_key="..."
)

print(llm.invoke("def bubble_sort(): "))
```
