The preview is not meant to significantly increase cybersecurity capability beyond GPT-5.5, however it is trained to be more permissive for security-related tasks.<\/p>\n<p class=\"block core-block\">This news comes after the launch of <strong>Anthropic&#8217;s<\/strong> unreleased AI model called Claude Mythos Preview, which works to hunt and fix software flaws in an effort to &#8220;reshape&#8221; cybersecurity, Anthropic stated.<\/p>\n<p class=\"block core-block\">&#8220;We are focused on providing proportional safeguards and access to empower cyber defenders to protect society, and our approach has been informed by conversations with cybersecurity and national security leaders across federal and state government and major commercial entities,&#8221; OpenAI said in its announcement.\u00a0<\/p>\n<p class=\"block core-block\">&#8220;More specialized access becomes relevant only when authorized workflows still run into refusals. This occurs with higher risk workflows such as red teaming and penetration testing, where defenders may need to go beyond analysis and validate exploitability in a controlled environment. GPT\u20115.5\u2011Cyber is designed to facilitate these more specialized dual-use workflows,&#8221; the company stated.<\/p>\n<p class=\"block core-block\">This launch is part of OpenAI&#8217;s Trusted Access for Cyber program. The pilot program was\u00a0announced\u00a0in February in an effort to &#8220;enhance baseline safeguards for all users while piloting trusted access for defensive acceleration.&#8221;\u00a0<\/p>\n<p class=\"block core-block\">Beginning June 1, individuals using the most permissive cyber models through the program will need to enable Advanced Account Security, the company added.<\/p>\n<p class=\"block core-block\">This move comes as AI capabilities surrounding cybersecurity have reached a &#8220;tipping point.&#8221; Government officials have recently raised concerns that artificial intelligence tools could be misused to disrupt critical&#8230;<\/p>\n<p><a href=\"https:\/\/www.benzinga.com\/markets\/private-markets\/26\/05\/52426435\/openai-launches-cybersecurity-preview-to-challenge-anthropics-mythos\">Source<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>OpenAI Launches Cybersecurity Preview To Challenge Anthropic&#8217;s Mythos https:\/\/www.benzinga.com\/markets\/private-markets\/26\/05\/52426435\/openai-launches-cybersecurity-preview-to-challenge-anthropics-mythos Publish Date: 2026-05-08 15:17:00 Source Domain:&#8230;<\/p>\n","protected":false},"author":1,"featured_media":241921,"comment_status":"closed","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"fifu_image_url":"https:\/\/cdn.benzinga.com\/files\/images\/story\/2026\/05\/08\/Germany---January-24-2023-Smartphone-Wit.jpeg?width=1200&height=800&fit=crop","fifu_image_alt":"","footnotes":""},"categories":[15],"tags":[20,57],"class_list":["post-241920","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-cybersecurity","tag-artificial-intelligence","tag-security"],"_links":{"self":[{"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/posts\/241920"}],"collection":[{"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/comments?post=241920"}],"version-history":[{"count":1,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/posts\/241920\/revisions"}],"predecessor-version":[{"id":241922,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/posts\/241920\/revisions\/241922"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/media\/241921"}],"wp:attachment":[{"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/media?parent=241920"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/categories?post=241920"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/tags?post=241920"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
