He made the comments at a Hong Kong science event, days after Tencent launched its new flagship open model, Hy4, on 4 November. Tencent says it excluded offensive security exploit material from Hy4's training data, training it on defensive security data instead. The company also says Hy4 has strong basic biology knowledge but is weaker than leading models at designing experiments, based on internal reviews. Hy4 ranks as the second-best Chinese model according to benchmarking firm Artificial Analysis. Yao argued a mix of open and closed models may work best since open models can help defenders too. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### What did Tencent say it left out of Hy4's training data for safety reasons? Tencent said it excluded material on exploiting software flaws from Hy4's training data, training the model on defensive security data instead. This was part of the launch announcement for Hy4, the company's new flagship open model released on 4 November. Tencent plans to also release Hy4's weights and a safety testing report. _Developers evaluating open-weight models for safety can track releases like this on daily.dev._ ### How does Tencent's Hy4 model compare to other Chinese AI models in benchmarks? Hy4 ranks as the second-best Chinese model according to benchmarking firm Artificial Analysis. Tencent also says Hy4 has strong basic knowledge of biology but is weaker than leading models at designing experiments, based on internal expert reviews rather than independent testing. _Engineers comparing frontier model benchmarks can follow coverage like this on daily.dev._ ### Why does Tencent's chief AI scientist think biology risks from AI could be harder to manage than cyber risks? Yao Shunyu, Tencent's chief AI scientist, said AI models' cyber abilities and soon their biology abilities will reach a threshold where real harm becomes possible, and he specifically warned that biology risks may be harder to manage than cyber risks. He argued companies releasing open, downloadable models need to take safety especially seriously. _Those weighing open versus closed model risk tradeoffs can follow this debate on daily.dev._ ## Similar posts on daily.dev - [OpenAI’s CFO says firms using Chinese AI models are risking security](https://daily.dev/posts/openai-s-cfo-says-firms-using-chinese-ai-models-are-risking-security-rpthbc7zf) · The Next Web · 1 upvotes · 0 comments - [China’s state security minister names two US AI models as a cyber threat](https://daily.dev/posts/china-s-state-security-minister-names-two-us-ai-models-as-a-cyber-threat-0o0f6ijzt) · The Next Web · 0 upvotes · 0 comments --- Tags: [#open-source](https://daily.dev/tags/open-source), [#llm](https://daily.dev/tags/llm), [#ai-safety](https://daily.dev/tags/ai-safety) [View this post on daily.dev](https://daily.dev/posts/tencent-ai-chief-warns-models-will-soon-pose-biology-risks-scmp-reports-cwmochqkb) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"Tencent AI chief warns models will soon pose biology risks, SCMP reports","url":"https://daily.dev/posts/tencent-ai-chief-warns-models-will-soon-pose-biology-risks-scmp-reports-cwmochqkb","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/tencent-ai-chief-warns-models-will-soon-pose-biology-risks-scmp-reports-cwmochqkb"},"datePublished":"2026-11-08T15:38:34.884Z","dateModified":"2026-11-08T15:39:04.318Z","description":"Tencent's chief AI scientist Yao Shunyu warns that AI models will soon reach a threshold where their biology capabilities could cause real harm, similar to...","image":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/5b51aa8279da3d74819cae9fae571f5e?_a=AQAEuop","thumbnailUrl":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/5b51aa8279da3d74819cae9fae571f5e?_a=AQAEuop","isAccessibleForFree":true,"articleSection":"The Next Web","inLanguage":"en","publisher":{"@type":"Organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180}},"author":{"@type":"Organization","name":"The Next Web","logo":"https://media.daily.dev/image/upload/t_logo,f_auto/v1/logos/tnw","url":"https://daily.dev/sources/tnw"},"commentCount":0,"discussionUrl":"https://daily.dev/posts/tencent-ai-chief-warns-models-will-soon-pose-biology-risks-scmp-reports-cwmochqkb","interactionStatistic":[{"@type":"InteractionCounter","interactionType":{"@type":"LikeAction"},"userInteractionCount":0},{"@type":"InteractionCounter","interactionType":{"@type":"CommentAction"},"userInteractionCount":0}],"keywords":"open-source,llm,ai-safety","timeRequired":"PT2M"} {"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"name":"Home","item":"https://daily.dev"},{"@type":"ListItem","position":2,"name":"The Next Web","item":"https://daily.dev/sources/tnw"},{"@type":"ListItem","position":3,"name":"Tencent AI chief warns models will soon pose biology risks, SCMP reports"}]} {"@context":"https://schema.org","@type":"FAQPage","@id":"https://daily.dev/posts/tencent-ai-chief-warns-models-will-soon-pose-biology-risks-scmp-reports-cwmochqkb#faq","mainEntity":[{"@type":"Question","name":"What did Tencent say it left out of Hy4's training data for safety reasons?","acceptedAnswer":{"@type":"Answer","text":"Tencent said it excluded material on exploiting software flaws from Hy4's training data, training the model on defensive security data instead.
