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

> 📢 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

> - GGUF: MiniCPM5-1B-Claude-Opus-Fable5-V2-Thinking-GGUF

GGUF quantizations of MiniCPM5-1B-Claude-Opus-Fable5-Thinking for llama.cpp, Ollama, LM Studio, jan, KoboldCpp, and other GGUF runtimes.

中文说明

This repository provides local-deployment builds of a 1B Thinking model fine-tuned on Fable 5 data atop openbmb/MiniCPM5-1B. The GGUF files embed MiniCPM5's native chat template for llama.cpp-compatible runtimes.

Quick start

llama.cpp (llama-cli)

llama-cli \
  -m MiniCPM5-1B-Claude-Opus-Fable5-Thinking-Q8_0.gguf \
  -p "Write a Python function to merge two sorted lists." \
  -n 512 \
  --temp 0.9 --top-p 0.95 \
  -c 8192

> The model supports up to 128K tokens (131,072) per config.json. Set -c according to your available VRAM/RAM.

llama.cpp server

llama-server \
  -m MiniCPM5-1B-Claude-Opus-Fable5-Thinking-Q8_0.gguf \
  -c 8192 --port 8080

LM Studio / jan / KoboldCpp

Load any .gguf file from this repository. The MiniCPM5 chat template is embedded in the GGUF metadata.

Sampling recommendations

Generation defaults are inherited from 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 |

Capabilities

• Fable 5 fine-tune — post-trained on Fable 5 data
• Coding — code generation, debugging, and software-engineering workflows
• Instruction following — more reliable adherence to user prompts and task constraints
• Thinking mode — chain-of-thought reasoning; MiniCPM5 chat template baked into the GGUF
• Long context — up to 128K tokens (131,072 tokens per upstream config.json)

---

Limitations

• Thinking outputs — the model may emit reasoning blocks before the final answer
• 1B scale — lightweight local deployment; not frontier-scale
• Runtime context — actual usable context depends on your GGUF runtime and hardware limits
