Claude Opus 4.5 is Anthropic's most advanced AI model, purpose-built for demanding technical and analytical work. It delivers state-of-the-art performance in coding, agentic workflows, and computer use, while also excelling at everyday tasks like deep research and working with slides and spreadsheets. Available through the Claude API, apps, and all three major cloud platforms, Opus 4.5 is priced at $5/$25 per million tokens, making frontier-level intelligence more accessible than ever.
Claude Opus 4.5 achieves top scores on SWE-bench Verified, a rigorous test of real-world software engineering. Developers report that tasks which were near-impossible for Sonnet 4.5 just weeks earlier are now within reach, with the model often cutting token usage in half while solving the same problems.
The model excels at powering autonomous agents that plan, reason about tradeoffs, and call tools effectively. Early testers describe it as the clear winner for frontier task planning and tool calling, making it ideal for code migration, refactoring, and other complex multi-step workflows.
At $5/$25 per million tokens, Opus 4.5 brings Opus-level capabilities to a broader audience. Customers report that the model uses fewer tokens to solve problems compared to competitors, meaning the efficiency compounds at scale.
Beyond coding, Opus 4.5 handles deep research, slide creation, and spreadsheet work with meaningfully better results. Long conversations in Claude apps no longer hit a wall, and new integrations with Excel, Chrome, and desktop expand its utility.
"Opus models have always been 'the real SOTA' but have been cost prohibitive in the past. Claude Opus 4.5 is now at a price point where it can be your go-to model for most tasks."
This quote from a CEO with early access captures the product's defining edge: it combines frontier intelligence with accessible pricing. Where previous Opus models were reserved for the most critical tasks, Opus 4.5 can serve as a daily driver across coding, research, and office work. Testers consistently note that the model "gets it" — handling ambiguity and reasoning about tradeoffs without requiring hand-holding.
You're a developer or team leader who needs a model that can reliably tackle complex software engineering, agentic workflows, and analytical tasks without breaking the budget. If you've been waiting for an Opus-class model that's both powerful and practical for everyday use, Claude Opus 4.5 delivers exactly that.

Whats 1Code? An app to run your Claude Code agents in parallel that works on Mac and Web. On Mac - run locally, with or without worktrees. On Web - run in remote sandboxes with live previews of your app, mobile included, so you can check on agents from anywhere. Running multiple Claude Codes in parallel dramatically sped up how we build features.
We introduce PersonaPlex, a full-duplex conversational AI model that enables natural conversations with customizable voices and roles. PersonaPlex handles interruptions and backchannels while maintaining any chosen persona, outperforming existing systems on conversational dynamics and task adherence.
