レビュー
Opus 4.5 is a strong choice for projects requiring advanced reasoning, mathematics, and heavy automation, making it well-suited for developers, researchers, and automation engineers. However, it is not the top pick for casual conversation.
長所
- Mathematics and computation: Ranks high across comparison benchmarks, well-suited for complex problems
- Logical reasoning and analysis: Strong scores in reasoning tasks, ideal for deep logical analysis and problem-solving
- AI Agents & Automation: Strong in autonomous systems, well-suited for building autonomous agents and workflow automation
短所
- General/casual conversation is not a strength; not the first choice for conversational chatbots or customer service

Access Claude Opus 4.5 via claude.ai (Pro/Team/Enterprise plans) or the Anthropic API under model ID `claude-opus-4-5`. Released in November 2025, it was the first model to cross 80% on SWE-bench Verified (scoring 80.9%), excelling most in coding agents, computer use, and complex agentic workflows. Best used for long-horizon programming tasks, multi-step automation, or deep reasoning needs—avoid using it for simple tasks due to higher costs compared to Sonnet. Tip: combine with tools/MCP to leverage the model's agentic capabilities.
