## 2. Improvement |
|
|
|
Compared to the previous version DeepSeek-V2-Chat, the new version has made the following improvements: |
|
|
|
| **Benchmark** | **DeepSeek-V2-Chat** | **DeepSeek-V2-Chat-0628** | **Improvement** | |
|
|:-----------:|:------------:|:---------------:|:-------------------------:| |
|
| **HumanEval** | 81.1 | 84.8 | +3.7 | |
|
| **MATH** | 53.9 | 71.0 | +17.1 | |
|
| **BBH** | 79.7 | 83.4 | +3.7 | |
|
| **IFEval** | 63.8 | 77.6 | +13.8 | |
|
| **Arena-Hard** | 41.6 | 68.3 | +26.7 | |
|
| **JSON Output (Internal)** | 78 | 85 | +7 | |
|
|
|
Furthermore, the instruction following capability in the "system" area has been optimized, significantly enhancing the user experience for immersive translation, RAG, and other tasks. |
|
|
|
## 3. How to run locally |
|
|
|
**To utilize DeepSeek-V2-Chat-0628 in BF16 format for inference, 80GB*8 GPUs are required.** |
|
### Inference with Huggingface's Transformers |
|
You can directly employ [Huggingface's Transformers](https://github.com/huggingface/transformers) for model inference. |
|
|
|
```python |
|
import torch |
|
from transformers import AutoTokenizer, AutoModelForCausalLM, GenerationConfig |
|
|
|
model_name = "deepseek-ai/DeepSeek-V2-Chat-0628" |
|
tokenizer = AutoTokenizer.from_pretrained(model_name, trust_remote_code=True) |
|
# `max_memory` should be set based on your devices |
|
max_memory = {i: "75GB" for i in range(8)} |
|
# `device_map` cannot be set to `auto` |
|
model = AutoModelForCausalLM.from_pretrained(model_name, trust_remote_code=True, device_map="sequential", torch_dtype=torch.bfloat16, max_memory=max_memory, attn_implementation="eager") |
|
model.generation_config = GenerationConfig.from_pretrained(model_name) |
|
model.generation_config.pad_token_id = model.generation_config.eos_token_id |
|
|
|
messages = [ |
|
{"role": "user", "content": "Write a piece of quicksort code in C++"} |
|
] |
|
input_tensor = tokenizer.apply_chat_template(messages, add_generation_prompt=True, return_tensors="pt") |
|
outputs = model.generate(input_tensor.to(model.device), max_new_tokens=100) |
|
|
|
result = tokenizer.decode(outputs[0][input_tensor.shape[1]:], skip_special_tokens=True) |
|
print(result) |
|
``` |
|
|
|
The complete chat template can be found within `tokenizer_config.json` located in the huggingface model repository. |
|
|
|
**Note: The chat template has been updated compared to the previous DeepSeek-V2-Chat version.** |
|
|
|
An example of chat template is as belows: |
|
|
|
```bash |
|
<｜begin▁of▁sentence｜><｜User｜>{user_message_1}<｜Assistant｜>{assistant_message_1}<｜end▁of▁sentence｜><｜User｜>{user_message_2}<｜Assistant｜> |
|
``` |
|
|
|
You can also add an optional system message: |
|
|
|
```bash |
|
<｜begin▁of▁sentence｜>{system_message} |
|
|
|
<｜User｜>{user_message_1}<｜Assistant｜>{assistant_message_1}<｜end▁of▁sentence｜><｜User｜>{user_message_2}<｜Assistant｜> |
|
``` |
|
|
|
### Inference with vLLM (recommended) |
|
To utilize [vLLM](https://github.com/vllm-project/vllm) for model inference, please merge this Pull Request into your vLLM codebase: https://github.com/vllm-project/vllm/pull/4650. |
|
|
|
```python |
|
from transformers import AutoTokenizer |
|
from vllm import LLM, SamplingParams |
|
|
|
max_model_len, tp_size = 8192, 8 |
|
model_name = "deepseek-ai/DeepSeek-V2-Chat-0628" |
|
tokenizer = AutoTokenizer.from_pretrained(model_name) |
|
llm = LLM(model=model_name, tensor_parallel_size=tp_size, max_model_len=max_model_len, trust_remote_code=True, enforce_eager=True) |
|
sampling_params = SamplingParams(temperature=0.3, max_tokens=256, stop_token_ids=[tokenizer.eos_token_id]) |
|
|
|
messages_list = [ |
|
[{"role": "user", "content": "Who are you?"}], |
|
[{"role": "user", "content": "Translate the following content into Chinese directly: DeepSeek-V2 adopts innovative architectures to guarantee economical training and efficient inference."}], |
|
[{"role": "user", "content": "Write a piece of quicksort code in C++."}], |
|
] |
|
|
|
prompt_token_ids = [tokenizer.apply_chat_template(messages, add_generation_prompt=True) for messages in messages_list] |
|
|
|
outputs = llm.generate(prompt_token_ids=prompt_token_ids, sampling_params=sampling_params) |
|
|
|
generated_text = [output.outputs[0].text for output in outputs] |
|
print(generated_text) |
|
``` |
