Claude 3: Haiku, Sonnet, and Opus Explained for Business Leaders

Anthropic launched Claude 3 on March 4, 2024 with three distinct models. Opus scores 86.8% on MMLU, outperforming GPT-4 on several reasoning and analysis benchmarks. Sonnet is the right default for most executive professional work. Haiku handles high-volume tasks at low cost and sub-second latency.

Business Impact

Eliminates: Overpaying for Opus-level capability on simple tasks, or underperforming with Haiku on complex analysis

Time back: Matching the right model to each task saves cost and improves output quality on complex work

Best for: Executives evaluating which Claude 3 tier to use for daily work and team workflows

Executive Action Steps

• Access Sonnet free at Claude.ai or subscribe to Claude.ai Pro ($20/month) for Opus.
• Use Haiku (via API) for classification, tagging, and high-volume simple tasks.
• Use Sonnet as the default for daily professional drafting, review, and research.
• Reserve Opus for complex contract review, strategic documents, and multi-step reasoning.

Why it matters: The three-tier structure means right-sizing the model to the task, not defaulting to the most expensive or the cheapest option for everything.

Copilot Pro is an individual subscription that embeds GPT-4 Turbo directly into the Microsoft 365 Office apps. It requires only a personal Microsoft 365 subscription, with no enterprise agreement or organizational deployment needed. The AI appears in the app ribbon alongside the document you are already working in.

Business Impact

Eliminates: Context-switching to a separate AI tool for document drafting, email replies, and spreadsheet analysis

Time back: 1 to 3 hr/week per user across Word, Outlook, Excel, and PowerPoint

Best for: Individual executives and small teams on personal or small-business Microsoft 365 plans

Executive Action Steps

• Subscribe at copilot.microsoft.com/pro with an active Microsoft 365 Personal or Family plan.
• Open Word and click the Copilot button in the Home ribbon to open the Copilot pane.
• Run the payback test: describe a document topic and outline, ask Copilot to draft it, and measure time saved versus writing from scratch.
• Extend to Excel: describe the analysis you need in the Copilot pane and let it build the formulas and charts.

Why it matters: GPT-4 Turbo inside the document means no copy-paste, no context switching, and no additional tool to manage. The 10-minute payback test makes the ROI case immediately visible.

Google Workspace Gemini: AI in Gmail, Docs, and Sheets for Teams

Google replaced the Duet AI brand with Gemini across Google Workspace in early 2024, integrating more capable models into Gmail, Docs, Sheets, Slides, and Meet. For teams already running on Google Workspace, the upgrade arrives in the tools the team uses every day without any new software to install.

Business Impact

Eliminates: Manual email drafting, meeting note formatting, and plain-language formula writing in Sheets

Time back: 2 to 4 hr/week for teams with heavy Gmail and Docs usage

Best for: Google Workspace Business Standard and above teams, especially sales and operations teams drafting volume email

Executive Action Steps

• Admin enables Gemini in Google Admin Console under Apps > Workspace > Gemini for Google Workspace.
• In Gmail, click Help me write in a new compose window and test with a standard client email.
• In Docs, open the Gemini sidebar and ask it to draft a section from a bullet-point outline.
• In Sheets, ask Gemini to write a formula from a plain-language description of the calculation needed.

Why it matters: Gemini is now embedded in Workspace rather than being a parallel tool. The lowest-friction AI upgrade for any team already on Google Workspace.

03 / Pro Tip

Claude 3 Sonnet for Rapid Contract Review: 60 Minutes to 5

Tools: Claude.ai (Sonnet or Opus) | Time: 5 Min | Level: Intermediate

Executives review contracts regularly and every one takes 30 to 90 minutes of careful reading. Claude 3 Sonnet, available free on Claude.ai, handles the first-layer review with strong accuracy on standard commercial contract types. Its 200K context window fits most contracts in a single pass. This prompt produces a structured review with key terms, risk flags, and open questions for legal counsel.

The Prompt

Why it works: Structured output with six named sections turns a 60-minute read into a 5-minute review. Section 5 converts the legal briefing from open-ended to specific, which reduces counsel time and cost.

Best for: Executives who review 2 to 5 contracts per month and want to cut first-read time and arrive at legal review with specific questions already formed.
