inclusionAI releases SingProbe streaming guardrail probe for Qwen3.8-27B

inclusionAI has released Qwen3.8-27B-singprobe, a 10.1M-parameter intrinsic streaming guardrail that reuses Qwen3.8-27B hidden states to score query intent, response unsafety, and hallucination risk at every token.

The probe adds less than 0.5% decode-time overhead and reports a 0.03% benign-response false-positive rate averaged across five datasets. It is supported through SGLang and vLLM integration branches, with training code available at inclusionAI/SingProbe.
