Claude Opus 4.8: what changed
Anthropic says Opus 4.8 “builds on Opus 4.7 with improvements across benchmarks” and is “a more effective collaborator,” and that it is available today “for the same price.” (https://www.anthropic.com/news/claude-opus-4-8)
Anthropic also says Opus 4.8 is available via the Claude API as claude-opus-4-8. (https://www.anthropic.com/news/claude-opus-4-8)
New: effort control on claude.ai
Anthropic says users on claude.ai now have a control to choose “how much effort Claude puts into a task,” trading off response depth vs. speed and rate-limit usage. (https://www.anthropic.com/news/claude-opus-4-8)
New (research preview): dynamic workflows in Claude Code
Anthropic says Claude Code now has a new “dynamic workflows” feature (research preview) that allows it to tackle very large-scale problems by running hundreds of parallel subagents in a single session and verifying outputs before reporting back. (https://www.anthropic.com/news/claude-opus-4-8)
Anthropic's terminal-based AI coding agent with Claude Opus 4.7, /ultrareview, Routines, /ultraplan, and 80.9% SWE-bench
In Claude’s documentation post, Claude describes dynamic workflows as orchestration scripts that run tens to hundreds of parallel subagents in a single session, checking work before anything reaches you. (https://claude.com/blog/introducing-dynamic-workflows-in-claude-code)
Claude says dynamic workflows are available in research preview in the Claude Code CLI, Desktop, and VS Code extension for Max, Team, and Enterprise (if admin enabled) plans, and are also available via the Claude API and on Amazon Bedrock, Google Cloud Vertex AI, and Microsoft Foundry.
