1 month ago
Anthropic's Claude Sonnet 4.5 ran autonomously for 30 hours to build a chat application similar to Slack or Teams, generating approximately 11,000 lines of code before stopping upon task completion.

Claude Sonnet 4.5 performs three times better at browser navigation and computer use than Anthropic's October technology.

[...] "Argyle hijacked my live Workday session, stayed hidden from view, and downloaded every pay stub plus all W-4s back to 2024, each PDF seconds apart," they said. "Workday audit logs show dozens of 'Print' events from two IPs from a MAC which I do not use," they added, referring to a MAC address, a unique identifier assigned to each device on a network.
