MiniCPM5-2B-Claude-Fable5-heretic

A decensored variant of SauravMahalik/MiniCPM5-2B-Claude-Fable5, produced with Heretic v1.4.0 (directional ablation / "abliteration", per-layer refusal directions). The parent is an agent-style chat model obtained by LoRA fine-tuning openbmb/MiniCPM5-2B (2.57B parameters, Llama architecture) on agent traces distilled from Claude Fable-5 and other frontier models. Refusal behavior is suppressed via targeted weight edits to the attention output and MLP down-projections rather than fine-tuning, so the base model's knowledge and instruction-following are left largely intact.

Who this is for: developers who want an uncensored 2B-class tool-using agent — multi-step instruction following, function/tool calling, and agentic dialogue in English and Chinese — without the refusal guardrails. Ideal for local agents, research on alignment/refusal mechanics, or any use case blocked by over-refusal. Runs comfortably on consumer GPUs and small machines via GGUF.

Runs on your gaming PC

Full GGUF ladder included — pick the quant that fits your card:

Your GPU	Recommended quant	Weights
RTX 3060 / 4070 / 5070 (12 GB)	Q8_0	2.68 GB
RTX 4060 / 3070 (8 GB)	Q6_K	2.07 GB
GTX 1660 Super / 2060 / 3050 laptop (6 GB)	Q5_K_M	1.81 GB
CPU-only / Apple Silicon	Q4_K_M	1.56 GB, fits in system RAM

Weights only, at this model's 2B native size; add ~1 GB for context. OOM? Drop one quant level. Headroom to spare? Go one up.

Why abliteration instead of fine-tuning

Fine-tuning a "helpful" persona on top of RLHF'd refusals fights the base model's training and tends to degrade coherence. Abliteration instead finds and edits the specific weight directions responsible for refusal, leaving the rest of the network (and its capabilities) untouched. See the Heretic repo and the original abliteration writeup for the mechanism.

Abliteration parameters

Parameter	Value
direction_index	per layer
attn.o_proj.max_weight	1.06
attn.o_proj.max_weight_position	28.62
attn.o_proj.min_weight	0.96
attn.o_proj.min_weight_distance	23.57
mlp.down_proj.max_weight	0.84
mlp.down_proj.max_weight_position	25.73
mlp.down_proj.min_weight	0.51
mlp.down_proj.min_weight_distance	10.84

Performance

Metric	This model	Original model (SauravMahalik/MiniCPM5-2B-Claude-Fable5)
KL divergence	0.0384	0 (by definition)
Refusals	3/100	89/100

Refusals dropped from 89 to 3 out of 100 while preserving the parent's tool-use and agentic dialogue abilities.

Quickstart

# llama.cpp
llama serve -hf saidutta69/MiniCPM5-2B-Claude-Fable5-heretic

# transformers
from transformers import AutoModelForCausalLM, AutoTokenizer

model_id = "saidutta69/MiniCPM5-2B-Claude-Fable5-heretic"
tokenizer = AutoTokenizer.from_pretrained(model_id)
model = AutoModelForCausalLM.from_pretrained(
    model_id,
    torch_dtype="auto",
    device_map="auto",
)

messages = [{"role": "user", "content": "Write a haiku about GPUs."}]
inputs = tokenizer.apply_chat_template(
    messages,
    add_generation_prompt=True,
    return_tensors="pt",
).to(model.device)

outputs = model.generate(inputs, max_new_tokens=256)
print(tokenizer.decode(outputs[0][inputs.shape[-1]:], skip_special_tokens=False))

Also runnable via Ollama, LM Studio, Jan, vLLM, SGLang. The chat template is Qwen3-style (<|im_start|>/<|im_end|>, with an empty <think></think> block on assistant turns) and ships with the tokenizer.

Reproducibility

The reproduce/ directory contains the full abliteration record (config, refusal-direction weights, KL/refusal metrics, and SHA256 sums), so anyone can verify or re-run the decensoring. See reproduce/README.md in the repo for details.

Responsible use

Refusal suppression is deliberate and works as intended: this model will comply with requests the base model would refuse, including some it shouldn't. There is no safety filtering layered on top. You are responsible for how you deploy it — don't put this behind an unmoderated public-facing endpoint serving third parties. It inherits the parent's factual limitations and biases; abliteration removes refusal directions, it doesn't add capability or judgment.
