      "q": "Which AI model should I use for writing?",
      "a": "Claude Sonnet 4.5 is the strongest long-form writer of the flagship tier — clearer voice, fewer hallucinations, better at following style guides. For short-form marketing copy GPT-5 is competitive at lower cost."
    },
    {
      "q": "Which AI model should I use for coding?",
      "a": "Claude Sonnet 4.5 in Claude Code, Cursor, or Cline. SWE-bench Verified ~62% as of early 2026. For pure autocomplete GitHub Copilot's underlying GPT-4o variant is fine and 3-5× cheaper."
    },
    {
      "q": "Which AI model should I use for spreadsheets and data?",
      "a": "GPT-5 with the structured-output mode plus the Code Interpreter / Advanced Data Analysis tool. Gemini 2.5 Pro is a close second when the data fits its 1M-token context."
    },
    {
      "q": "Which AI model is best for an agent?",
      "a": "GPT-5 leads on multi-step tool use as of 2026. Claude Sonnet 4.5 is a near-equal on tool selection but slightly weaker at long agent loops. For cost-sensitive routers use Haiku 4 or GPT-5 mini."
