该版本主要扩展了 API 对 Managed Agents 的支持，新增了模型努力程度控制、初始会话事件以及线程增量流式处理能力。
新增 API 支持：Managed Agents 模型努力程度：现在可以在请求中指定 Managed Agents 的模型努力程度（model effort），用于控制模型在任务上的推理或计算资源投入程度。
新增 API 支持：初始会话事件（initial session events）：在创建或启动会话时，现在可以获取初始会话事件，便于在会话生命周期早期进行事件驱动的逻辑处理。
新增 API 支持：线程增量流式处理（threads delta streaming）：针对线程（threads）的更新，引入了增量流式处理模式，允许客户端以流式方式接收线程状态的增量变化，减少全量轮询开销。

# Claude SDK for Python
[](https://pypi.org/project/anthropic/)
The Claude SDK for Python provides access to the [Claude API](https://docs.anthropic.com/en/api/) from Python applications.
## Documentation
Full documentation is available at **[platform.claude.com/docs/en/api/sdks/python](https://platform.claude.com/docs/en/api/sdks/python)**.
## Installation
```sh
pip install anthropic
```
## Getting started

import os
from anthropic import Anthropic
client = Anthropic(
api_key=os.environ.get("ANTHROPIC_API_KEY"), # This is the default and can be omitted
)
message = client.messages.create(
max_tokens=1024,
messages=[
{
"role": "user",
"content": "Hello, Claude",
}
],
model="claude-opus-4-6",
)
print(message.content)
```
