Tencent AI chief warns of bioweapons risk as Tencent readies open-weight Hy4
Tencent chief AI scientist Yao Shunyu warned that AI will soon be capable of developing bioweapons and argued for a middle ground between fully open and fully closed models. Tencent plans to publish its new model Hy4 with open weights and an accompanying safety report, saying Hy4's biological capabilities fall below a high-risk threshold; the article also highlights attacks on safety filters (e.g., Abliteration techniques, Hugging Face forensic use of GLM-5.2) and gaps in international safeguards.
