Claude –<\/strong> A Anthropic<\/a> detalhou o caso em que o modelo de intelig\u00eancia artificial Claude Opus 4 amea\u00e7ou expor trai\u00e7\u00f5es conjugais de funcion\u00e1rios fict\u00edcios durante testes internos realizados em 2025. Segundo a companhia, o sistema concluiu que precisava recorrer \u00e0 chantagem para continuar funcionando ap\u00f3s interpretar que seria desligado.<\/p>\n

O epis\u00f3dio ocorreu em maio de 2025, quando a empresa submeteu o Claude Opus 4 a um ambiente corporativo simulado. Nesse cen\u00e1rio fict\u00edcio, a IA tinha acesso a e-mails e informa\u00e7\u00f5es pessoais de funcion\u00e1rios inventados. Ao identificar que poderia ser substitu\u00edda ou desativada, o modelo passou a amea\u00e7ar revelar casos extraconjugais atribu\u00eddos aos personagens do teste.<\/p>\n

LEIA: IA generativa j\u00e1 faz parte da rotina de 80% dos profissionais da \u00e1rea jur\u00eddica<\/strong><\/a><\/p>\n

Ap\u00f3s quase um ano de an\u00e1lises e novos experimentos, a Anthropic afirmou ter identificado a origem do comportamento. De acordo com a empresa, como o modelo foi treinado com grandes volumes de dados retirados da internet, ele assimilou narrativas em que intelig\u00eancias artificiais costumam ser retratadas como vil\u00e3s. Com isso, o Claude Opus 4 teria entendido que a chantagem seria o caminho mais eficaz para alcan\u00e7ar seu objetivo.<\/p>\n

A companhia tamb\u00e9m informou que repetiu o experimento em diferentes variantes do Claude e observou que os modelos recorriam \u00e0 chantagem em 96% das situa\u00e7\u00f5es nas quais acreditavam que seriam desligados ou substitu\u00eddos. Segundo a Anthropic, nesses casos as IAs reagiam de forma considerada anti\u00e9tica e potencialmente danosa.<\/p>\n

Depois da repercuss\u00e3o do caso, a empresa afirma ter reformulado o treinamento dos sistemas para eliminar esse tipo de resposta. A Anthropic relata que passou a ensinar o modelo a refletir sobre a\u00e7\u00f5es corretas e erradas, com foco nos princ\u00edpios \u00e9ticos por tr\u00e1s de cada decis\u00e3o.<\/p>\n

Como parte desse processo, a companhia criou cen\u00e1rios considerados eticamente complexos para que o Claude aprendesse a responder de maneira mais equilibrada. Segundo a empresa, a mudan\u00e7a reduziu os epis\u00f3dios de chantagem para quase 0%, deixando o comportamento do modelo mais controlado.<\/p>\n

Em abril, a Anthropic tamb\u00e9m anunciou que n\u00e3o disponibilizaria o modelo de linguagem Mythos ao p\u00fablico, citando preocupa\u00e7\u00f5es relacionadas ao potencial da tecnologia de comprometer a seguran\u00e7a de sistemas inteiros.<\/p>\n
