Claude Code Update: Sonnet 5 Becomes the Default, Dynamic Workflows Roll Out

Anthropic has shipped a wave of updates to Claude Code, its command-line and IDE-integrated coding agent. Here’s what changed:

  • Claude Sonnet 5 is now the default model in Claude Code, bringing a native 1M-token context window. Introductory pricing of $2 per million input tokens and $10 per million output tokens runs through August 31, 2026 (shipped in v2.1.197).
  • Dynamic workflows are now on by default for Max and Team plan users, as well as API users. You can ask Claude to build a multi-agent workflow directly, or enable the Claude Code-specific ultracode setting to opt in.
  • Claude in Chrome has reached general availability, letting Claude Code interact with the browser directly as part of agent workflows.
  • Agent sessions now support background notifications — sessions that need input or that finish will fire agent_needs_input / agent_completed hooks, useful for long-running unattended tasks.
  • A new /dataviz skill was added, giving Claude Code built-in design guidance for building charts and dashboards.
  • Reliability got a boost: a streaming idle watchdog is now on by default across all providers, automatically aborting and retrying a request if the response stream stalls for 5+ minutes.
  • Draft PR handoff and improved failover round out the update, making longer agent-driven coding sessions more resilient.
  • On the enterprise side, a new Claude Apps Gateway for Amazon Bedrock and Google Cloud gives organizations a self-hosted control plane for Claude Code, with SSO, centrally enforced policy, role-based access, and per-user cost tracking.
  • Org-level model restrictions can now be enforced across the model picker, --model, /model, and the ANTHROPIC_MODEL environment variable, showing a clear “restricted by your organization’s settings” message when applicable.

Why it matters: the combination of a stronger default model, workflow automation, and enterprise controls signals that Anthropic is positioning Claude Code as a serious platform for both individual developers and larger engineering organizations — not just a coding assistant.
