Claude Mythos Preview + 81k survey: Anthropic puts safety and economics on the table

Anthropic shipped two research-side items in late June: Claude Mythos Preview, framed as 'strikingly capable' at computer-security tasks with a published evaluation methodology, and an 81,000-person Claude user survey that links stated economic concerns to patterns in Claude traffic. The same stretch also brought a PNNL partnership on critical-infrastructure defense.
