tokenizer = AutoTokenizer.from_pretrained("nvcky/MiniFABLECPM5-Thinking")
model = AutoModelForCausalLM.from_pretrained("nvcky/MiniFABLECPM5-Thinking")
messages = [
    {"role": "user", "content": "Who are you?"},
]
inputs = tokenizer.apply_chat_template(
	messages,
	add_generation_prompt=True,
	tokenize=True,
	return_dict=True,
	return_tensors="pt",
).to(model.device)

# MiniCPM5-1B-Claude-Opus-Fable5-Thinking

> **📢 V2.0 已发布** — 我们已发布增强 **工具调用** 能力的新版本，欢迎通过以下链接下载体验：
> - Transformers：[MiniCPM5-1B-Claude-Opus-Fable5-V2-Thinking](https://huggingface.co/GnLOLot/MiniCPM5-1B-Claude-Opus-Fable5-V2-Thinking)
> - GGUF：[MiniCPM5-1B-Claude-Opus-Fable5-V2-Thinking-GGUF](https://huggingface.co/GnLOLot/MiniCPM5-1B-Claude-Opus-Fable5-V2-Thinking-GGUF)

GGUF 量化版：**[MiniCPM5-1B-Claude-Opus-Fable5-Thinking-GGUF](https://huggingface.co/GnLOLot/MiniCPM5-1B-Claude-Opus-Fable5-Thinking-GGUF)**

[English README](./README.md)

**MiniCPM5-1B-Claude-Opus-Fable5-Thinking** 是基于 [openbmb/MiniCPM5-1B](https://huggingface.co/openbmb/MiniCPM5-1B) 的 1B **Thinking** 语言模型。该模型使用 **Fable 5** 数据进一步微调，增强了 **Coding（编程）** 与 **指令遵循（Instruction Following）** 能力，同时保留 MiniCPM5 原生的 Thinking 对话模板与工具调用格式。

llama.cpp / Ollama / LM Studio 部署请参阅 **[GGUF 仓库](https://huggingface.co/GnLOLot/MiniCPM5-1B-Claude-Opus-Fable5-Thinking-GGUF)**。

## 模型概述

| 项目 | 说明 |
|---|---|
| **基座模型** | [openbmb/MiniCPM5-1B](https://huggingface.co/openbmb/MiniCPM5-1B)（1B 稠密 Llama 架构） |
| **后训练数据** | Fable 5 traces |
| **主要提升** | 相较基座，Coding 与指令遵循能力更强 |
| **对话格式** | MiniCPM5 原生 Thinking 模板，支持可选的思维链推理块 |
| **上下文长度** | **128K**（`max_position_embeddings = 131072`） |
| **部署特点** | 单卡友好，适合边缘 / 本地场景 |

---

## 能力

- **Coding** — 代码生成、调试及软件工程类任务
- **Instruction Following** — 更稳定地遵循用户提示与结构化任务约束
- **Thinking 模式** — 通过 MiniCPM5 对话模板进行思维链推理
- **工具调用** — 继承 MiniCPM5 的 XML 工具调用格式
- **长上下文** — 最高 **128K tokens**（`config.json` 中为 131,072）

## 快速开始

```python
from transformers import AutoModelForCausalLM, AutoTokenizer
import torch

model_id = "GnLOLot/MiniCPM5-1B-Claude-Opus-Fable5-Thinking"

tokenizer = AutoTokenizer.from_pretrained(model_id, trust_remote_code=True)
model = AutoModelForCausalLM.from_pretrained(
    model_id, trust_remote_code=True,
    torch_dtype=torch.bfloat16, device_map="auto",
)

messages = [{"role": "user", "content": "写一个 Python 函数，合并两个有序链表。"}]
text = tokenizer.apply_chat_template(messages, tokenize=False, add_generation_prompt=True)
inputs = tokenizer(text, return_tensors="pt").to(model.device)
outputs = model.generate(**inputs, max_new_tokens=512, do_sample=False)
print(tokenizer.decode(outputs[0][inputs["input_ids"].shape[1]:], skip_special_tokens=True))
```

## 采样建议

生成参数继承自 **[MiniCPM5-1B](https://huggingface.co/openbmb/MiniCPM5-1B)**：

| 模式 | 参数 |
|---|---|
| **Think**（默认） | `temperature=0.9, top_p=0.95` |
| **No Think** | `temperature=0.7, top_p=0.95`，`enable_thinking=False` |

---

## 局限性

- **Thinking 输出** — 模型可能在最终回答前输出推理块；下游应用可在展示前将其剥离
- **1B 体量** — 面向轻量本地部署，非前沿规模通用推理模型
