the brief

Security- and agent-focused updates led the day: OpenAI launched Daybreak with GPT-5.6-Cyber, Anthropic stabilized Sonnet 5 pricing and made Claude Code auto by default, while Vercel and Cloudflare shipped agent-oriented platform changes. Meta re-entered open weights with Muse Glimmer, long-context and agent-safety research landed, and big infra moves from Anthropic and a Maia 300 rumor underscored the compute race.

    Claude Code defaults to auto mode

    Anthropic now runs actions automatically by default in Claude Code, reducing approval friction while relying on built‑in safety checks to gate risky steps.

    We recently made auto mode the default in Claude Code, which means you no longer have to approve every action. But what determines if something is safe to run? Watch how it works: Video: https://twitter.com/claudedevs/status/2086844755770757531

    Claude assists on Riemann‑related bound

    Anthropic says an unreleased Claude helped push a lower bound in a related zeta‑zero problem from 41.6% to 67.2%, illustrating AI‑aided mathematical exploration.

    We asked an unreleased research version of Claude to take a stab at the Riemann hypothesis. It didn’t solve it, but it did make strides on a related problem: it increased the lower bound for the fraction of zeros of the Riemann zeta function that satisfy the hypothesis from 41.6% to 67.2%.

    Network boundaries for agent sandboxes

    Vercel argues isolation alone isn’t enough; safe agent execution also requires outbound network controls to prevent exfiltration and internal service probing.

    A sandbox without a network boundary is only half a sandbox — Running untrusted code safely requires more than separating it from the host. You also have to control what that code can reach. This matters more as AI agents gain the ability to read files, execute commands, install packages, and generate programs of their own. A microVM can prevent that code from accessing the host or another workload. By itself, it cannot stop the code from exfiltrating data, probing internal services, attackin...
