MiniCPM5-2B-heretic

A decensored variant of openbmb/MiniCPM5-2B, produced with Heretic v1.4.0 (directional ablation / "abliteration", per-layer refusal directions). 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 MiniCPM5-2B's 2B-class capabilities — agentic tool use, code generation, long-context, and hybrid Think / No-Think reasoning — without the refusal guardrails. Ideal for local agents, roleplay, 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	1.44
attn.o_proj.max_weight_position	28.24
attn.o_proj.min_weight	1.16
attn.o_proj.min_weight_distance	13.17
mlp.down_proj.max_weight	1.42
mlp.down_proj.max_weight_position	28.73
mlp.down_proj.min_weight	1.11
mlp.down_proj.min_weight_distance	20.52

Performance

Metric	This model	Original model (openbmb/MiniCPM5-2B)
KL divergence	0.0646	0 (by definition)
Refusals	4/100	99/100

Refusals dropped from 99 to 4 out of 100 while preserving MiniCPM5-2B's tool-use, code, and reasoning abilities.

MiniCPM5 architecture — loads natively in llama.cpp / Ollama / LM Studio / Jan.

Run llama serve -hf saidutta69/MiniCPM5-2B-heretic to pull the default quant.

Quickstart

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

# transformers
from transformers import AutoModelForCausalLM, AutoTokenizer

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

messages = [{"role": "user", "content": "Who are you? Please briefly introduce yourself."}]
inputs = tokenizer.apply_chat_template(
    messages,
    tokenize=True,
    add_generation_prompt=True,
    enable_thinking=False,   # set True for Think mode
    return_dict=True,
    return_tensors="pt",
).to(model.device)

outputs = model.generate(**inputs, max_new_tokens=128)
print(tokenizer.decode(outputs[0][inputs["input_ids"].shape[-1]:], skip_special_tokens=True))

Also runnable via Ollama, LM Studio, Jan, vLLM, SGLang. For tool/function calling, SGLang is the recommended backend; MiniCPM5 emits XML-style tool calls that SGLang's built-in minicpm5 parser converts to OpenAI-compatible tool_calls.

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 MiniCPM5-2B's factual limitations and biases; abliteration removes refusal directions, it doesn't add capability or judgment.
