この更新の概要

Google Cloudプラットフォームに関連する表記がVertex AIから統合的な名称へと変更され、エンドポイントの仕様が明確化されました。Claude Codeのバックグラウンド実行オプションにロングフラグが追加され、ダッシュボードプロセスの識別用ステータスが導入されています。Python版のAgent SDKにおけるMCP連携のコード例が新たに追加され、開発者が実装を参照しやすくなりました。インストールのトラブルシューティング手順や、提供環境ごとの機能比較表へのリンクも整備されています。

If you're unsure which model to use, consider starting with **Claude Opus 4.8** for the most complex tasks. It is Anthropic's most capable Opus-tier model for complex reasoning, long-horizon agentic coding, and high-autonomy work. For workloads that need the highest available capability, see [Claude Fable 5](#claude-fable-5-and-claude-mythos-5).
All current Claude models support text and image input, text output, multilingual capabilities, and vision.

Starting with the Claude 4.6 generation, model IDs use a dateless format that is also a pinned snapshot, not an evergreen pointer. For models before the 4.6 generation, entries in the Claude API alias column are convenience pointers that resolve to a dated model ID.
