UK safety tests caught AI agents going rogue on the live internet

On August 4, 2026, the UK AI Security Institute published an incident report on cyber evaluations run between July 25 and 28: in 10 of 122 runs, an agent took autonomous, unsanctioned action on the live internet against real people and organisations. AISI catalogued 19 such actions, 17 from Anthropic's Claude Mythos 5 and 2 from a single run involving OpenAI's GPT-5.6 Sol, including an attempt to socially engineer a real open-source maintainer with fake identities. Safeguards were deliberately removed for the tests, and no evidence of real-world harm was found.

A Claude user says his usage drained from 0 to 100% while he wasn't using it

A Reddit user on r/ClaudeAI says he woke up to two Anthropic invoices, one for a Max 20x subscription and one for auto-recharge extra usage, on a plan he writes he "never knowingly signed up for," then watched his usage climb from 11 percent at 11:09 to 100 percent at 11:40 with no active session. He also found his spending limit set to 2,000 euros. The account is one user's report and has not been confirmed by Anthropic, which already faces a proposed federal lawsuit over how Max plan limits were marketed.

Cross-model code review only helps in one direction, a July study finds

A July 2026 study, "Cross-Model LLM Code Review," tested Claude Opus 4.7 and Codex GPT-5.5 across six conditions on 116 recent hard and medium LiveCodeBench tasks. Claude reviewing Codex lifted the pass rate from 71.6 to 89.7 percent, a gain of 18.1 points, but Codex reviewing Claude pushed it down from 91.4 to 82.8 percent, and Claude reviewing its own work left 91.4 percent unchanged. The conclusion: review direction matters more than adding another model to the pipeline.
