What is Qwen 2.5 7B?

In addition, as a model family, Qwen 2.5 also includes other models, covering different parameter sizes, context windows, and specialized domains (general, code, and math).

Qwen 2.5 Family

Diverse Model Architectures and Scales
The Qwen2.5 series covers model sizes ranging from 0.5B to 72B parameters, meeting the needs of various scenarios from lightweight to large-scale applications.
The number of layers and attention heads (Q/KV) increases with model size, resulting in greater model complexity.

Context Window and Generation Length
Most base models have a context length of 128K, while smaller models (0.5B, 1.5B, 3B) have 32K, and Math versions have 4K.
The mainstream generation length is 8K, while Coder and Math versions have 2K.

Changes in Tie Embedding
Smaller models (0.5B, 1.5B, 3B) and all Coder/Math-1.5B versions use Tie Embedding, while larger models do not.
This may help improve parameter efficiency and generalization for smaller models.

Rich Model Types
In addition to general-purpose models, there are also Coder (code-specialized) and Math (math-specialized) sub-series, meeting the needs of different vertical domains.

from openai import OpenAI
  
client = OpenAI(
    base_url="https://api.novita.ai/v3/openai",
    api_key="<YOUR Novita AI API Key>",
)

model = "qwen/qwen2.5-7b-instruct"
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)
