Libraries

How to use nvcky/MiniFABLECPM5-Thinking with Transformers:

# Use a pipeline as a high-level helper
from transformers import pipeline

]
pipe(messages)

# Load model directly
from transformers import AutoTokenizer, AutoModelForCausalLM

tokenizer = AutoTokenizer.from_pretrained("nvcky/MiniFABLECPM5-Thinking")
model = AutoModelForCausalLM.from_pretrained("nvcky/MiniFABLECPM5-Thinking")
messages = [
    {"role": "user", "content": "Who are you?"},

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

	> 📢 V2.0 is available — We have released an updated model with enhanced tool-calling capabilities. Welcome to try the new version:
	> - 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 quantizations for local deployment: [MiniCPM5-1B-Claude-Opus-Fable5-Thinking-GGUF](https://huggingface.co/GnLOLot/MiniCPM5-1B-Claude-Opus-Fable5-Thinking-GGUF)

	[中文说明](./README-cn.md)

	MiniCPM5-1B-Claude-Opus-Fable5-Thinking is a compact 1B Thinking language model built on [openbmb/MiniCPM5-1B](https://huggingface.co/openbmb/MiniCPM5-1B). It is further fine-tuned on Fable 5 data to improve coding and instruction-following while keeping MiniCPM5's native Thinking chat template and tool-call format.

	For llama.cpp / Ollama / LM Studio deployment, see the [GGUF repository](https://huggingface.co/GnLOLot/MiniCPM5-1B-Claude-Opus-Fable5-Thinking-GGUF).

	## Overview

	\| Item \| Detail \|
	\|---\|---\|
	\| Base model \| [openbmb/MiniCPM5-1B](https://huggingface.co/openbmb/MiniCPM5-1B) (1B dense Llama architecture) \|
	\| Post-training \| Fable 5 traces \|
	\| Key gains \| Stronger coding and instruction following vs. the base checkpoint \|
	\| Chat format \| MiniCPM5 native Thinking template with optional chain-of-thought blocks \|
	\| Context length \| 128K (`max_position_embeddings = 131072`) \|
	\| Deployment \| Single-GPU friendly; suitable for edge / local use \|

	---

	## Capabilities

	- Coding — code generation, debugging, and software-engineering-style tasks
	- Instruction following — more reliable adherence to user prompts and structured constraints
	- Thinking mode — chain-of-thought reasoning via the MiniCPM5 chat template
	- Tool calling — inherits MiniCPM5's XML tool-call format
	- Long context — up to 128K tokens (131,072 tokens per `config.json`)

	---

	## Quick start

	```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": "Write a Python function to merge two sorted lists."}]
	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))
	```

	---

	## Sampling recommendations

	Generation defaults are inherited from [MiniCPM5-1B](https://huggingface.co/openbmb/MiniCPM5-1B):

	\| Mode \| Params \|
	\|---\|---\|
	\| Think (default) \| `temperature=0.9, top_p=0.95` \|
	\| No Think \| `temperature=0.7, top_p=0.95`, `enable_thinking=False` \|

	---

	## Limitations

	- Thinking outputs — the model may emit reasoning blocks before the final answer; downstream apps can strip them before display
	- 1B scale — optimized for lightweight local deployment, not frontier-scale general reasoning
