+## Introduction
+We are excited to introduce **Seed-X**, a powerful open-source multilingual translation language model series, including instruction and reasoning models, with 7B parameters pushing the boundaries of translation capabilities.
+We develop Seed-X as an accessible, off-the-shelf tool to support the community in advancing translation research and applications:
+* **Exceptional translation capabilities**: Seed-X exhibits state-of-the-art translation capabilities, on par with or outperforming ultra-large models like Gemini-2.5, Claude-3.5, and GPT-4, as validated by human evaluations and automatic metrics.
+* **Deployment and inference-friendly**: With a compact 7B parameter count and mistral architecture, Seed-X offers outstanding translation performance in a lightweight and efficient package, ideal for deployment and inference.
+* **Broad domain coverage**: Seed-X excels on a highly challenging translation test set spanning diverse domains, including the internet, science and technology, office dialogues, e-commerce, biomedicine, finance, law, literature, and entertainment.

+
+This repo contains the Seed-X-PPO model, with the following features:
+* Type: Causal language models
+* Training Stage: Pretraining & Post-training
+* Support: Multilingual translation among 28 languages

+## Model Downloads
+| Model Name  | Description | Download |
+| ----------- | ----------- |-----------
+| Seed-X-Instruct  | Instruction-tuned for alignment with user intent. |🤗 [Model]()|
+| 👉 **Seed-X-PPO** | RL trained to boost translation capabilities.     | 🤗 [Model]()|
+|Seed-X-RM | Reward model to evaluate the quality of translation.|  🤗 [Model]()| 
+
+## Quickstart
+Here is a simple example demonstrating how to load the model and perform translation using ```vllm```
+```python
+from vllm import LLM, SamplingParams
+
+model_path = "./ByteDance-Seed/Seed-X-PPO-7B"
+
+model = LLM(model=model_path,
+            max_num_seqs=512,
+            tensor_parallel_size=8,
+            enable_prefix_caching=True, 
+            gpu_memory_utilization=0.95)
+
+messages = [
+    "Translate the following English sentence into Chinese:\nMay the force be with you <zh>", # without CoT
+    "Translate the following English sentence into Chinese and explain it in detail:\nMay the force be with you <zh>" # with CoT
+]
+
+sampling_params = SamplingParams(temperature=0,
+                                 max_tokens=4096,
+                                 skip_special_tokens=True)
+
+results = model.generate(messages, sampling_params)
+responses = [res.outputs[0].text.strip() for res in results]
+
+print(responses)
+```
+## Evaluation
+We evaluated Seed-X on a diverse set of translation benchmarks, including FLORES-200, WMT-25, and a publicly released [challenge set](https://github.com/ByteDance-Seed/Seed-X-7B/tree/main/challenge_set) accompanied by human evaluations.
