The speed at which Mythos uncovers software vulnerabilities and can potentially arm bad actors for cyberattacks was at the heart of the concern.\n\nWashington hasn't only picked on Anthropic. It also [kept OpenAI from broadly releasing its GPT-5.6 model](https://www.thedeepview.com/articles/how-openai-s-gpt-5-6-just-edged-past-mythos), leading OpenAI CEO Sam Altman to call it \"[bad news](https://x.com/sama/status/2070607488274358364)\" on X. Altman said, \"At the request of the US government, it is launching today in limited preview instead of the open access launch we were planning.\" That was despite the fact that GPT-5.6 has tested even stronger than Mythos in some benchmarks. There's no word yet on when the government will clear GPT-5.6 for general use.\n\n## Our Deeper *View*\n\nPerhaps the most notable outcome of the US government's standoff with Anthropic — and OpenAI now as well — is that it has resulted in a pause in promulgating these ever-powerful models. Such a pause to evaluate and prepare for the effects of the latest models had appeared highly unlikely. While leaders such as Anthropic CEO Dario Amodei have extolled the benefits of such a pause to assess safety, they've also made it clear they wouldn't do it unless other labs agree to a similar pause, because otherwise it wouldn't be effective. Will the staggered rollouts of Mythos and GPT-5.5 reset the expectations and norms for the way the most powerful frontier models are launched? If you are concerned about AI safety, that would be a win. The question would then shift to the who and the how of such a pause.", "url": "https://wpnews.pro/news/us-government-clears-mythos-ai-expectations-shift", "canonical_source": "https://www.thedeepview.com/articles/us-government-clears-mythos-ai-expectations-shift", "published_at": "2026-07-01 02:03:00+00:00", "updated_at": "2026-07-01 05:28:31.005586+00:00", "lang": "en", "topics": ["ai-safety", "ai-policy", "large-language-models"], "entities": ["Anthropic", "Mythos", "Fable", "Howard Lutnick", "US Commerce Department", "OpenAI", "GPT-5.6", "Sam Altman"], "alternates": {"html": "https://wpnews.pro/news/us-government-clears-mythos-ai-expectations-shift", "markdown": "https://wpnews.pro/news/us-government-clears-mythos-ai-expectations-shift.md", "text": "https://wpnews.pro/news/us-government-clears-mythos-ai-expectations-shift.txt", "jsonld": "https://wpnews.pro/news/us-government-clears-mythos-ai-expectations-shift.jsonld"}}
