Claude Opus 4.8 becomes new default, adds dynamic multi-agent workflows
Anthropic has made Claude Opus 4.8 the default model for Max, Team Premium, Enterprise, and API accounts, with high-effort reasoning enabled by default and an /effort xhigh flag for the most demanding tasks. A new dynamic workflows feature lets Claude write orchestration scripts that coordinate dozens to hundreds of subagents, significantly expanding agentic task scope. A security-guidance plugin also ships this week, performing real-time vulnerability review of Claude's own code changes.

Claude Code auto mode expands to Pro plan with Sonnet 4.6 support
Auto mode in Claude Code is now available on Pro accounts, supporting Sonnet 4.6 alongside Opus and replacing explicit permission prompts with background safety checks. New tooling includes a /usage command that attributes plan consumption by skill, subagent, plugin, and MCP server, and a /code-review command that surfaces correctness bugs. Background sessions now persist and are accessible via /resume, improving continuity for long-running agentic tasks.
