+# 🚀 MiniMax 模型 Transformers 部署指南
+
+## 📖 简介
+
+本指南将帮助您使用 [Transformers](https://huggingface.co/docs/transformers/index) 库部署 MiniMax-M1 模型。Transformers 是一个广泛使用的深度学习库，提供了丰富的预训练模型和灵活的模型操作接口。
+
+## 🛠️ 环境准备
+
+### 安装 Transformers
+
+```bash
+pip install transformers torch accelerate
+```
+
+## 📋 基本使用示例
+
+预训练模型可以按照以下方式使用：
+
+```python
+from transformers import AutoModelForCausalLM, AutoTokenizer, GenerationConfig
+
+MODEL_PATH = "{MODEL_PATH}"
+model = AutoModelForCausalLM.from_pretrained(MODEL_PATH, device_map="auto", trust_remote_code=True)
+tokenizer = AutoTokenizer.from_pretrained(MODEL_PATH, trust_remote_code=True)
+
+messages = [
+    {"role": "user", "content": [{"type": "text", "text": "What is your favourite condiment?"}]},
+    {"role": "assistant", "content": [{"type": "text", "text": "Well, I'm quite partial to a good squeeze of fresh lemon juice. It adds just the right amount of zesty flavour to whatever I'm cooking up in the kitchen!"}]},
+    {"role": "user", "content": [{"type": "text", "text": "Do you have mayonnaise recipes?"}]}
+]
+
+text = tokenizer.apply_chat_template(
+    messages,
+    tokenize=False,
+    add_generation_prompt=True
+)
+
+model_inputs = tokenizer(text, return_tensors="pt").to(model.device)
+
+generation_config = GenerationConfig(
+    max_new_tokens=20,
+    eos_token_id=tokenizer.eos_token_id,
+    use_cache=True,
+)
+
+generated_ids = model.generate(**model_inputs, generation_config=generation_config)
+
+generated_ids = [
+    output_ids[len(input_ids):] for input_ids, output_ids in zip(model_inputs.input_ids, generated_ids)
+]
+
+response = tokenizer.batch_decode(generated_ids, skip_special_tokens=True)[0]
+print(response)
+```
+
+## ⚡ 性能优化
+
+### 使用 Flash Attention 加速
+
+上面的代码片段展示了不使用任何优化技巧的推理过程。但通过利用 [Flash Attention](../perf_train_gpu_one#flash-attention-2)，可以大幅加速模型，因为它提供了模型内部使用的注意力机制的更快实现。
+
+首先，确保安装最新版本的 Flash Attention 2：
+
+```bash
+pip install -U flash-attn --no-build-isolation
+```
+
+还要确保您拥有与 Flash-Attention 2 兼容的硬件。在[Flash Attention 官方仓库](https://github.com/Dao-AILab/flash-attention)的官方文档中了解更多信息。此外，请确保以半精度（例如 `torch.float16`）加载模型。
+
+要使用 Flash Attention-2 加载和运行模型，请参考以下代码片段：
+
+```python
+import torch
+from transformers import AutoModelForCausalLM, AutoTokenizer
+
+MODEL_PATH = "{MODEL_PATH}"
+model = AutoModelForCausalLM.from_pretrained(MODEL_PATH, trust_remote_code=True, torch_dtype=torch.float16, attn_implementation="flash_attention_2", device_map="auto")
+tokenizer = AutoTokenizer.from_pretrained(MODEL_PATH, trust_remote_code=True)
+
+prompt = "My favourite condiment is"
+
+model_inputs = tokenizer([prompt], return_tensors="pt").to("cuda")
+generated_ids = model.generate(**model_inputs, max_new_tokens=100, do_sample=True)
+response = tokenizer.batch_decode(generated_ids)[0]
+print(response)
+```

+# 🚀 Guia de Deploy do Modelo MiniMax com Transformers
+
+[Transformers中文版部署指南](./transformers_deployment_guide_cn.md)
+
+## 📖 Introdução
+
+Este guia irá te ajudar a fazer o deploy do modelo MiniMax-M1 utilizando a biblioteca [Transformers](https://huggingface.co/docs/transformers/index). O Transformers é uma biblioteca de deep learning amplamente utilizada, que oferece uma vasta coleção de modelos pré-treinados e interfaces flexíveis para operação dos modelos.
+
+## 🛠️ Configuração do Ambiente
+
+### Instalando o Transformers
+
+```bash
+pip install transformers torch accelerate
+```
+
+## 📋 Exemplo de Uso Básico
+
+O modelo pré-treinado pode ser utilizado da seguinte maneira:
+
+```python
+from transformers import AutoModelForCausalLM, AutoTokenizer, GenerationConfig
+
+MODEL_PATH = "{MODEL_PATH}"
+model = AutoModelForCausalLM.from_pretrained(MODEL_PATH, device_map="auto", trust_remote_code=True)
+tokenizer = AutoTokenizer.from_pretrained(MODEL_PATH, trust_remote_code=True)
+
+messages = [
+    {"role": "user", "content": [{"type": "text", "text": "What is your favourite condiment?"}]},
+    {"role": "assistant", "content": [{"type": "text", "text": "Well, I'm quite partial to a good squeeze of fresh lemon juice. It adds just the right amount of zesty flavour to whatever I'm cooking up in the kitchen!"}]},
+    {"role": "user", "content": [{"type": "text", "text": "Do you have mayonnaise recipes?"}]}
+]
+
+text = tokenizer.apply_chat_template(
+    messages,
+    tokenize=False,
+    add_generation_prompt=True
+)
+
+model_inputs = tokenizer(text, return_tensors="pt").to(model.device)
+
+generation_config = GenerationConfig(
+    max_new_tokens=20,
+    eos_token_id=tokenizer.eos_token_id,
+    use_cache=True,
+)
+
+generated_ids = model.generate(**model_inputs, generation_config=generation_config)
+
+generated_ids = [
+    output_ids[len(input_ids):] for input_ids, output_ids in zip(model_inputs.input_ids, generated_ids)
+]
+
+response = tokenizer.batch_decode(generated_ids, skip_special_tokens=True)[0]
+print(response)
+```
+
+## ⚡ Otimização de Desempenho
+
+### Acelerando com Flash Attention
+
+O exemplo acima mostra uma inferência sem nenhum tipo de otimização. No entanto, é possível acelerar significativamente o modelo utilizando [Flash Attention](../perf_train_gpu_one#flash-attention-2), que é uma implementação mais rápida do mecanismo de atenção usado no modelo.
+
+Primeiro, certifique-se de instalar a versão mais recente do Flash Attention 2:
+
+```bash
+pip install -U flash-attn --no-build-isolation
+```
+
+Além disso, é necessário que seu hardware seja compatível com o Flash Attention 2. Consulte mais informações na documentação oficial do [repositório do Flash Attention](https://github.com/Dao-AILab/flash-attention). Também é recomendado carregar seu modelo em meia precisão (por exemplo, `torch.float16`).
+
+Para carregar e executar um modelo utilizando Flash Attention 2, utilize o exemplo abaixo:
+
+```python
+import torch
+from transformers import AutoModelForCausalLM, AutoTokenizer
+
+MODEL_PATH = "{MODEL_PATH}"
+model = AutoModelForCausalLM.from_pretrained(MODEL_PATH, trust_remote_code=True, torch_dtype=torch.float16, attn_implementation="flash_attention_2", device_map="auto")
+tokenizer = AutoTokenizer.from_pretrained(MODEL_PATH, trust_remote_code=True)
+
+prompt = "My favourite condiment is"
+
+model_inputs = tokenizer([prompt], return_tensors="pt").to("cuda")
+generated_ids = model.generate(**model_inputs, max_new_tokens=100, do_sample=True)
+response = tokenizer.batch_decode(generated_ids)[0]
+print(response)
+```
