# MiniCPM5-1B-Claude-Opus-Fable5-V2-Thinking

GGUF 量化版：**[MiniCPM5-1B-Claude-Opus-Fable5-V2-Thinking-GGUF](https://huggingface.co/GnLOLot/MiniCPM5-1B-Claude-Opus-Fable5-V2-Thinking-GGUF)**

[English README](./README.md)

**MiniCPM5-1B-Claude-Opus-Fable5-V2-Thinking** 是基于 [openbmb/MiniCPM5-1B](https://huggingface.co/openbmb/MiniCPM5-1B) 的 1B **Thinking** 语言模型。相对 V1，本 V2 版本在 **Fable 5** 数据上进一步微调，重点增强了 **工具调用（Tool Calling / Function Calling）**，同时继续提升 **Coding** 与 **指令遵循**，并保留 MiniCPM5 原生 Thinking 对话模板与 XML 工具调用格式。

上一版本：**[MiniCPM5-1B-Claude-Opus-Fable5-Thinking](https://huggingface.co/GnLOLot/MiniCPM5-1B-Claude-Opus-Fable5-Thinking)**（V1）

llama.cpp / Ollama / LM Studio 部署请参阅 **[GGUF 仓库](https://huggingface.co/GnLOLot/MiniCPM5-1B-Claude-Opus-Fable5-V2-Thinking-GGUF)**。

## 快速开始

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

model_id = "GnLOLot/MiniCPM5-1B-Claude-Opus-Fable5-V2-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
