Option 1: Direct API Integration (Python Example)

To get started, simply use the code snippet below:

from openai import OpenAI
  
client = OpenAI(
    base_url="https://api.novita.ai/v3/openai",
    api_key="session_Ntg-O34ZOS-q5bNnkb3IcixmWnmxEQBxwKWMW3es3CD7KG4PEhFE1yRTRMGS3s8zZ52hrMdz14MmI4oalaDJTw==",
)

model = "deepseek/deepseek-r1-0528"
stream = True # or False
max_tokens = 2048
system_content = ""Be a helpful assistant""
temperature = 1
top_p = 1
min_p = 0
top_k = 50
presence_penalty = 0
frequency_penalty = 0
repetition_penalty = 1
response_format = { "type": "text" }

chat_completion_res = client.chat.completions.create(
    model=model,
    messages=[
        {
            "role": "system",
            "content": system_content,
        },
        {
            "role": "user",
            "content": "Hi there!",
        }
    ],
    stream=stream,
    max_tokens=max_tokens,
    temperature=temperature,
    top_p=top_p,
    presence_penalty=presence_penalty,
    frequency_penalty=frequency_penalty,
    response_format=response_format,
    extra_body={
      "top_k": top_k,
      "repetition_penalty": repetition_penalty,
      "min_p": min_p
    }
  )

if stream:
    for chunk in chat_completion_res:
        print(chunk.choices[0].delta.content or "", end="")
else:
    print(chat_completion_res.choices[0].message.content)
  
  

Key Features:

• Unified endpoint:/v3/openai supports OpenAI’s Chat Completions API format.
• Flexible controls: Adjust temperature, top-p, penalties, and more for tailored results.
• Streaming & batching: Choose your preferred response mode.
