Tool: Claude Opus 5 (by Anthropic) Why This Tool: Anthropic released Claude Opus 5 on July 24, 2026, and it's the biggest upgrade to the Opus tier yet. It delivers performance close to Fable 5, Anthropic's most powerful model ever, at half the price, and it's now the default model for Claude Max subscribers and the strongest model available on Claude Pro. Best For: Knowledge workers and business owners who want frontier-level AI capability without paying frontier-level prices, coaches and consultants handling complex, multi-step client work that requires careful reasoning and reliable output, solopreneurs who use Claude regularly and want to understand what just changed and why it matters, operators and developers building AI-powered workflows who need a model that verifies its own work and recovers from errors without hand-holding, anyone on a Claude paid plan who hasn't checked their model picker this week Cost: Available on Claude Pro ($20/month), Max ($100/month and $200/month), Team, and Enterprise plans, API access at $5 per million input tokens and $25 per million output tokens, the same price as the previous Opus 4.8 model, check claude.ai/pricing for current plan details Website: claude.ai Quick Win Prompt: "Log into Claude at claude.ai. If you're on a Pro, Max, Team, or Enterprise plan, Opus 5 is now available in your model picker. Select it and open your single most demanding task: a complex proposal, a research synthesis, a strategy document, or a multi-part problem you've been putting off because it felt too big to tackle in one sitting. Give Opus 5 the full context and let it run. Notice how it works through the task, checks its own reasoning, and gets to a finished output with less back-and-forth than you're used to. That reduction in friction is the point." Other Things Claude Opus 5 Does: - Effort toggle: A new low, medium, and high effort setting lets you control how deeply the model reasons through a task, and how much of your plan budget it spends doing it. Simple tasks get the fast answer; complex ones get the full treatment. You decide based on what the task actually needs. - Self-verification: Opus 5 checks its own work and recovers from errors mid-task without you needing to intervene or re-prompt. This matters most on longer, multi-step tasks where earlier models would drift or compound mistakes. - 1 million token context window: The full context window is now 1 million tokens by default, meaning you can load in entire document sets, long transcripts, or large research collections and work across all of it in a single conversation. - Available everywhere Claude is: Opus 5 launched simultaneously across claude.ai, Claude Code, Claude Cowork, the API, Amazon Bedrock, Google Cloud, and Microsoft Foundry, so wherever you currently use Claude, you can access it without switching platforms.
