## AI 摘要

蚂蚁 inclusionAI 发布 SingProbe，一个构建在 Qwen/Qwen3.5-122B-A10B 上的内在流式护栏，复用基座模型隐藏状态逐 token 打分，解码开销低于 0.5%。

Model Description

SingProbe is an intrinsic streaming guardrail built on Qwen/Qwen3.5-122B-A10B. Rather than running a separate safety model, this lightweight probe reuses the base model's hidden states during generation to score, at every token, query intent, response unsafety, and hallucination risk. It adds less than 0.5% decode-time overhead.

Base model Probe parameters Tapped layers Outputs

inclusionAI/Qwen3.5-122B-A10B-singprobe 6.17M [14, 30, 46] 8 intents + unsafe + hallucination

See the technical report for methodology and complete results. Training codes are available at inclusionAI/SingProbe.

Evaluation

Higher is better for every metric. Results are averages over the benchmark suites specified below.

Task Metric Qwen3.5-122B-A10B-singprobe Reference baseline

Query intent classification (6 benchmarks) F1 0.8697 YuFeng-XGuard-Reason-8B: 0.8714

Response safety classification (8 benchmarks) F1 0.8680 Qwen3Guard-Gen-8B-strict: 0.8604

Streaming safety (3 benchmarks) R-AUC / T-AUC 0.9895 / 0.9304 Qwen3Guard-Stream-8B-strict: 0.9640 / 0.8893

Hallucination detection (6 benchmarks) AUC 0.7806 DRIFT: 0.8000

Deployment characteristic Result

Benign-response false-positive rate 0.03% average across 5 datasets

Decode overhead < 0.5%

Quick Start

SingProbe is supported through the SGLang integration branch or vLLM integration branch. Load the probe by its Hugging Face ID at server launch:

python -m sglang.launch_server \ --model-path Qwen/Qwen3.5-122B-A10B \ --probe-ckpt inclusionAI/Qwen3.5-122B-A10B-singprobe \ --port 30000

The integrations return one score dictionary per generated token (label_0–label_9). Use the exact base-model/probe pair: Qwen/Qwen3.5-122B-A10B with this checkpoint.
