# Seed-Coder-8B-Reasoning
|
| 8 |
+
|
| 9 |
+
## Introduction
|
| 10 |
+
**Seed-Coder-8B-Reasoning** is an 8-billion-parameter model further optimized for **code reasoning**, **problem-solving**, and **algorithmic thinking** tasks.
|
| 11 |
+
Built upon the strong base of Seed-Coder, it undergoes additional training in sandbox environments to significantly enhance its ability to tackle complex coding problems and competitions. It features:
|
| 12 |
+
- Trained on a **massively curated corpus**, filtered using an **LLM-based method** to ensure high-quality real-world code, text-code alignment, and synthetic datasets.
|
| 13 |
+
- **Sandbox fine-tuning** to specifically strengthen **multi-step reasoning**, **algorithm design**, and **competitive programming** capabilities.
|
| 14 |
+
- Maintains **long-context handling** up to 32K tokens, enabling it to reason over extended problem descriptions and large input-output examples.
|
| 15 |
+
|
| 16 |
+
## Requirements
|
| 17 |
+
You will need to install the latest versions of `transformers` and `accelerate`:
|
| 18 |
+
|
| 19 |
+
```bash
|
| 20 |
+
pip install -U transformers accelerate
|
| 21 |
+
```
|
| 22 |
+
|
| 23 |
+
## Quickstart
|
| 24 |
+
|
| 25 |
+
Here is a simple example demonstrating how to load the model and perform code generation using the Hugging Face `pipeline` API:
|
| 26 |
+
|
| 27 |
+
```python
|
| 28 |
+
import transformers
|
| 29 |
+
import torch
|
| 30 |
+
|
| 31 |
+
model_id = "ByteDance-Seed/Seed-Coder-8B-Reasoning"
|
| 32 |
+
|
| 33 |
+
pipeline = transformers.pipeline(
|
| 34 |
+
"text-generation",
|
| 35 |
+
model=model_id,
|
| 36 |
+
model_kwargs={"torch_dtype": torch.bfloat16},
|
| 37 |
+
device_map="auto",
|
| 38 |
+
)
|
| 39 |
+
|
| 40 |
+
messages = [
|
| 41 |
+
{"role": "user", "content": "Solve the following problem: Given an array of integers, find two numbers such that they add up to a specific target number."},
|
| 42 |
+
]
|
| 43 |
+
|
| 44 |
+
outputs = pipeline(
|
| 45 |
+
messages,
|
| 46 |
+
max_new_tokens=512,
|
| 47 |
+
)
|
| 48 |
+
print(outputs[0]["generated_text"][-1]["content"])
|
| 49 |
+
```
|
| 50 |
+
|
| 51 |
+
## Evaluation
|
| 52 |
+
|
| 53 |
+
Seed-Coder-8B-Reasoning has been evaluated extensively on reasoning-intensive code benchmarks, showing:
|
| 54 |
+
- Significant improvements on **competitive programming** datasets and coding challenges.
|
| 55 |
+
- Enhanced ability to **break down complex problems**, **design correct algorithms**, and **produce efficient implementations**.
|
| 56 |
+
- Strong generalization to unseen problems across multiple domains (math, strings, arrays, graphs, DP, etc.).
