Anthropic API
为了满足大家对 Anthropic API 生态的使用需求，我们的 API 新增了对 Anthropic API 格式的支持，其 base_url 为 https://api.deepseek.com/anthropic。
通过简单的配置，即可将 DeepSeek 的能力，接入到 Anthropic API 生态中。
将 DeepSeek 模型接入 Claude Code
请参考接入 Agent 工具
通过 Anthropic API 调用 DeepSeek 模型
- 安装 Anthropic SDK
pip install anthropic
- 配置环境变量
export ANTHROPIC_BASE_URL=https://api.deepseek.com/anthropic
export ANTHROPIC_API_KEY=${YOUR_API_KEY}
- 调用 API
import anthropic
client = anthropic.Anthropic()
message = client.messages.create(
model="deepseek-v4-pro",
max_tokens=1000,
system="You are a helpful assistant.",
messages=[
{
"role": "user",
"content": [
{
"type": "text",
"text": "Hi, how are you?"
}
]
}
]
)
print(message.content)
注意：当您给 DeepSeek 的 Anthropic API 传入不支持的模型名时，API 后端会自动将其映射到 deepseek-v4-flash 模型。
