# Deepseek V3.X

### DeepSeek V3.1

Thinking can be turned on and off by specifying the `thinking` parameter as a dictionary item in the `chat_template_kwargs` parameter of the body. It must be set to `true` or `false` not `"True"` or `"true"` .

Python + OpenAI Library:

```python
# pip install openai
from openai import OpenAI
import os

client = OpenAI(
    base_url="https://api.parasail.io/v1",
    api_key=os.environ["PARASAIL_API_KEY"]
)

chat_completion = client.chat.completions.create(
    model="parasail-deepseek-31",
    messages=[{"role": "user", "content": "What is the capital of New York?"}],
    extra_body={
        "chat_template_kwargs": {"thinking": True},  # or False, for no-think mode
    }
)

print(chat_completion.choices[0].message.content)
```

CURL:

{% code overflow="wrap" %}

```sh
curl -X POST https://api.parasail.io/v1/chat/completions \
    -H "Authorization: Bearer $PARASAIL_API_KEY" \
    -H "content-type: application/json" \
    -d '{"model": "parasail-deepseek-31", "chat_template_kwargs": {"thinking": false}, "messages": [{"role": "user", "content": "What is the capital of New York?"}]}'
```
