OpenAI rolled out a cybersecurity model<\/a> that rivals the capabilities of Mythos \u2014 without nearly as much fanfare or political pushback<\/a> as Anthropic received.<\/p>\n

Why it matters: The seemingly straightforward model release raises questions about what actually triggered the Trump administration’s concerns about Anthropic’s Fable 5 and Mythos 5.<\/p>\n

Catch up quick: OpenAI debuted an update to GPT-5.5-Cyber on Monday as part of a slew of announcements aimed at deepening its work with cybersecurity companies and researchers.<\/p>\n

Yes, but: The new GPT-5.5-Cyber achieved an 85.6% score in CyberGym, an internal benchmark that measures whether an AI agent can reproduce known software vulnerabilities.<\/p>\n

In comparison, Mythos 5 scored<\/a> 83.8% on the same evaluation.<\/p>\n

Between the lines: It’s unclear why OpenAI was able to move forward with this model release while Anthropic is stuck fighting export controls that bar it from allowing foreign nationals to use its models.<\/p>\n

The White House and OpenAI did not respond to requests for comment.<\/p>\n

The intrigue: OpenAI also said it has expanded its partnerships with organizations in Australia, Canada, France, Germany, Japan, Poland, South Korea and the EU.<\/p>\n

What to watch: Reports suggest that personality clashes<\/a> between Anthropic<\/a> and the Trump administration also prompted the export directive.<\/p>\n
