    {
      "q": "When should I pick o4 over GPT-5?",
      "a": "Hard math, formal proofs, deep debugging, competitive code, scientific reasoning where accuracy matters more than latency. o4 takes 10-40 seconds per response; users will not accept that in a chat interface."
    },
    {
      "q": "Is o4 better at coding than GPT-5?",
      "a": "On SWE-bench Verified, yes (~74% vs ~68%). On day-to-day coding inside an IDE where you need fast feedback, GPT-5 is usually preferable. Use o4 for hard debugging sessions where you hand it a large problem and come back later."
    },
    {
      "q": "What's the pricing difference?",
      "a": "GPT-5 is $5 input / $20 output per MTok. o4 is $12 / $48. Output-heavy reasoning traces mean o4 calls typically cost 5-10× more per call in practice."
    },
    {
      "q": "Can I use both in the same app?",
      "a": "Yes, and you should. Route easy requests to GPT-5 mini, medium to GPT-5, and hard (flagged by confidence or user) to o4. This architecture covers everything from chat to hard reasoning at a blended cost well below 'o4 everywhere'."
    },
    {
      "q": "Does o4 support function calling and structured output?",
      "a": "Yes, but GPT-5 handles both more reliably in practice. Tool use on o4 scores lower on tau-bench. Reserve o4 for the reasoning heavy lift; call tools from GPT-5."
