## Introduction
|
||||
We are thrilled to introduce Seed-Coder, a powerful, transparent, and parameter-efficient family of open-source code models at the 8B scale, featuring base, instruct, and reasoning variants. Seed-Coder contributes to promote the evolution of open code models through the following highlights.
|
||||
|
||||
- **Model-centric:** Seed-Coder predominantly leverages LLMs instead of hand-crafted rules for code data filtering, minimizing manual effort in pretraining data construction.
|
||||
- **Transparent:** We openly share detailed insights into our model-centric data pipeline, including methods for curating GitHub data, commits data, and code-related web data.
|
||||
- **Powerful:** Seed-Coder achieves state-of-the-art performance among open-source models of comparable size across a diverse range of coding tasks.

## Requirements
|
||||
You will need to install the latest versions of `transformers` and `accelerate`:
|
||||
|
||||
```bash
|
||||
pip install -U transformers accelerate
|
||||
```
|
||||
|
||||
## Quickstart
|
||||
|
||||
Here is a simple example demonstrating how to load the model and generate code using the Hugging Face `pipeline` API:
|
||||
|
||||
```python
|
||||
from transformers import AutoTokenizer, AutoModelForCausalLM
|
||||
import torch
|
||||
|
||||
model_id = "ByteDance-Seed/Seed-Coder-8B-Instruct"
|
||||
|
||||
tokenizer = AutoTokenizer.from_pretrained(model_id, trust_remote_code=True)
|
||||
model = AutoModelForCausalLM.from_pretrained(model_id, torch_dtype=torch.bfloat16, device_map="auto", trust_remote_code=True)
|
||||
|
||||
messages = [
|
||||
{"role": "user", "content": "Write a quick sort algorithm."},
|
||||
]
|
||||
|
||||
input_ids = tokenizer.apply_chat_template(
|
||||
messages,
|
||||
tokenize=True,
|
||||
return_tensors="pt",
|
||||
add_generation_prompt=True,
|
||||
).to(model.device)
|
||||
|
||||
outputs = model.generate(input_ids, max_new_tokens=512)
|
||||
response = tokenizer.decode(outputs[0][input_ids.shape[-1]:], skip_special_tokens=True)
|
||||
print(response)
|
||||
|
||||
```
|
||||
|
||||
