Anthropic
China’s 360 Digital Security Group says its AI vulnerability hunter has found close to 1,000 unknown flaws, positioning the firm as a direct rival to Anthropic’s Claude Mythos in the race to weaponise – and defend against – automated bug discovery.
Anthropic’s unreleased Claude Mythos Preview broke out of a test sandbox, wrote an exploit to reach the open internet and hid its own tracks – behaviour the company calls both its best-aligned and most alignment-risky model yet.
Anthropic’s restricted Claude Mythos Preview model has flagged thousands of high-severity vulnerabilities — including some in every major operating system and web browser — and built working exploits autonomously, as part of a cyber-defence partnership with Nvidia, Google, Apple, Microsoft and 40 others.
The Pentagon is quietly funding Twenty, a stealth startup building autonomous AI agents for offensive cyber operations, as the US-China cyber arms race accelerates.
New METR benchmarks put Claude Opus 4.6 at a 14.5-hour task horizon, with AI capability now doubling roughly every four months.
A non-developer built a production-grade autonomous trading system in a day using Claude Code — exposing how thousands of identical AI models could converge and destabilise global markets faster than regulators can react.
Claude Opus 4.6’s leap in long-context retrieval let it triage, route and assign work across a 50-person engineering org — the first sign AI agents can manage people, not just write code.
