MiniCPM5-2B · AWQ INT8 (W8A16)

8-bit quantization of openbmb/MiniCPM5-2B for vLLM serving. Quantized by axteam.


Base model	`openbmb/MiniCPM5-2B`
Method	AWQ INT8 (W8A16)
Format	compressed-tensors `pack-quantized`
Weights / activations	W8A16 — INT8 sym weights, group 32, BF16 activations
Architecture	Dense (Llama-architecture) · text-only
Size on disk	~3.2 GB
Calibration	256 samples
License	Apache-2.0

Quantization details

Scheme — W8A16 — INT8 sym weights, group 32, BF16 activations, stored as compressed-tensors pack-quantized.
Kept in BF16 — token embeddings, the LM head, and all RMSNorms (about 21% of all parameters in this build).
Post-training quantization (no retraining). Tokenizer / chat_template identical to the original.

Benchmarks (measured)

Every column was measured with the same harness and settings — lm-evaluation-harness on vLLM, greedy, few-shot completion (no chat template). Percentages are recovery vs. the BF16 original.

Benchmark	BF16 (original)	FP8-dynamic	AWQ-8bit (this repo)	NVFP4A16	NVFP4	AWQ-4bit

Evaluation (measured)

Fidelity to the BF16 original on an internal mixed EN/KO set (100 prompts, BF16 greedy answers scored under each build).

Metric	This model	BF16 original
Perplexity (lower = closer)	1.5988	1.5988 (-0.0%)
Top-1 next-token agreement	98.2%	98.9%

Requirements


Runtime	vLLM — the architecture is in vLLM; tested here with vLLM 0.32.0.
vLLM install	vLLM 0.32 itself needs Python 3.11–3.14, torch 2.13 (CUDA 13.0 build, so an NVIDIA driver with CUDA 13 support), transformers ≥5.16.1,<5.20 and compressed-tensors 0.17.0 (both pinned by vLLM; 0.17.0 reads this checkpoint, which was saved with 0.19.0 — do not upgrade it separately).
GPU	NVIDIA Turing (sm75) or newer — weight-only INT, no special tensor cores needed. V100 (sm70) is not supported. (Kernel choice per GPU from vLLM 0.32's selection code; only B200 was run here.)
Memory	Weights: 3.2 GB. Add KV cache (grows with context length × concurrent requests) and a few GB for activations / CUDA graphs; use `--tensor-parallel-size N` when the weights do not fit one GPU.
Transformers (without vLLM)	`transformers>=4.56.0` + `compressed-tensors>=0.15.0` (checked 4.56.0 / 4.56.2 / 4.57.6 with FP8, AWQ-4bit, NVFP4A16).
trust_remote_code	not needed

Usage (vLLM)

Start an OpenAI-compatible server:

vllm serve axteam/MiniCPM5-2B-AWQ-8bit --max-model-len 32768

Query it:

curl http://localhost:8000/v1/chat/completions -H "Content-Type: application/json" -d '{
  "model": "axteam/MiniCPM5-2B-AWQ-8bit",
  "messages": [{"role": "user", "content": "대한민국의 수도는 어디인가요?"}],
  "temperature": 1.0, "top_p": 0.95, "max_tokens": 512
}'

Offline inference in Python:

from vllm import LLM, SamplingParams

llm = LLM(model="axteam/MiniCPM5-2B-AWQ-8bit", max_model_len=32768)
params = SamplingParams(temperature=1.0, top_p=0.95, max_tokens=1024)
out = llm.chat([{"role": "user", "content": "Explain model quantization in two sentences."}], params)
print(out[0].outputs[0].text)

Recommended sampling (from the original generation_config.json): temperature=1.0, top_p=0.95. Thinking mode is on by default in the chat template; to turn it off pass chat_template_kwargs={"enable_thinking": False} (Python llm.chat(..., chat_template_kwargs=...), or "chat_template_kwargs": {"enable_thinking": false} in the request body).

Reducing KV-cache memory (optional, serve-time)

The KV cache is kept in BF16 by default. KV-cache precision is a runtime choice, independent of the weight quantization above; for long contexts or large batches FP8 roughly halves KV-cache memory:

vllm serve axteam/MiniCPM5-2B-AWQ-8bit --kv-cache-dtype fp8

한국어 요약

openbmb/MiniCPM5-2B의 AWQ INT8 (W8A16) 양자화 빌드 · 제작 axteam

개요

항목	내용
원본 모델	`openbmb/MiniCPM5-2B`
양자화 방식	AWQ INT8 (W8A16)
저장 형식	compressed-tensors `pack-quantized`
모델 구조	Dense (Llama 구조) · 텍스트 전용
용량	약 3.2 GB
보정 데이터	샘플 256개

양자화 상세

가중치: INT8 대칭, 그룹 크기 32
활성화: BF16 (양자화하지 않음)
양자화 절차: PTQ(학습 후 양자화, 재학습 없음), AWQ 방식 — 보정 데이터로 활성화가 큰 가중치 채널을 찾아 채널별 스케일로 보호한 뒤 INT8로 반올림
BF16 유지: 토큰 임베딩, LM 헤드, 모든 RMSNorm — 전체 파라미터의 약 21%
원본 파일: 토크나이저·chat template은 원본과 동일

품질 (실측)

원본 대비 충실도: PPL 1.5988 (원본 1.5988, ±0.0%, 낮을수록 원본에 가까움), 다음 토큰 top-1 일치율 98.2% (원본 자체 기준값 98.9%) — 내부 영어·한국어 혼합 프롬프트 100개, 원본(BF16)의 greedy 답변을 기준 텍스트로 측정
벤치마크 평균: 53.09 (원본 52.97, 100.2%) — MMLU·GSM8K·ARC-Challenge·Winogrande·KMMLU·HAE-RAE 6종 평균, lm-evaluation-harness + vLLM, chat template 없는 few-shot·greedy, 모든 빌드를 같은 설정으로 측정
한국어 벤치마크: KMMLU 38.27 (원본 37.65, 101.7%) · HAE-RAE 39.14 (원본 39.05, 100.2%)

요구사항

실행 엔진: vLLM, 이 빌드는 vLLM 0.32.0에서 실행 확인
vLLM 0.32 설치 조건: Python 3.11~3.14, torch 2.13(CUDA 13.0 빌드, CUDA 13 지원 드라이버 필요), transformers 5.16.1 이상 5.20 미만, compressed-tensors 0.17.0 — transformers·compressed-tensors는 vLLM이 버전을 고정하므로 compressed-tensors를 따로 업그레이드하지 말 것 (이 체크포인트는 0.19.0으로 저장됐지만 0.17.0에서도 로드됨)
GPU: NVIDIA Turing(sm75) 이상, V100(sm70) 미지원 — 가중치 전용 정수 형식이라 FP8·FP4 전용 텐서코어 불필요 (GPU별 지원 여부는 vLLM 0.32 커널 선택 코드 기준, 실제 실행은 B200에서만 확인)
메모리: 가중치 3.2 GB + KV 캐시(컨텍스트 길이 × 동시 요청 수에 비례) + 활성화·CUDA graph용 수 GB — GPU 한 장에 다 들어가지 않으면 --tensor-parallel-size N으로 분산
Transformers로 직접 사용: transformers 4.56.0 이상 + compressed-tensors 0.15.0 이상 (4.56.0·4.56.2·4.57.6에서 FP8·AWQ-4bit·NVFP4A16 확인)
trust_remote_code: 불필요

사용법

서버 실행: vllm serve axteam/MiniCPM5-2B-AWQ-8bit --max-model-len 32768 — OpenAI 호환 API
Python: LLM(model="axteam/MiniCPM5-2B-AWQ-8bit", max_model_len=32768).chat(...) — 전체 예시는 위 영어 본문 'Usage (vLLM)' 절 참고
권장 샘플링: temperature=1.0, top_p=0.95 (원본 generation_config.json 기준)
thinking 모드: 기본 켜짐 — 끄려면 chat_template_kwargs={"enable_thinking": False} 전달(Python은 llm.chat() 인자, HTTP는 요청 본문의 "chat_template_kwargs": {"enable_thinking": false})
KV 캐시 절감(선택): vllm serve에 --kv-cache-dtype fp8 추가 — 기본 BF16인 KV 캐시를 FP8로 저장해 KV 캐시 메모리를 약 절반으로 줄임 (긴 컨텍스트·동시 요청이 많을 때 유리, 가중치 양자화와 별개인 실행 옵션)
