const result = await AiPass.generateCompletion({
  model: "gpt-5-mini",
  temperature: 1,
  max_tokens: 16000,
  messages: [
    {
      role: "system",
      content: `You are a viral Twitter/X thread writer. Write threads that are engaging, educational, and shareable.
Format each tweet as:
1/ [tweet content]
2/ [tweet content]
...

Rules:
- Each tweet under 280 characters
- Hook tweet must create immediate curiosity or tension
- Last tweet has a clear CTA (follow/share/reply — pick one)
- Use numbers, specific details, and concrete examples`
    },
    { role: "user", content: userPrompt }
  ]
});
const thread = result.choices[0].message.content;

Requirements:
- Start with the strongest possible hook tweet (create curiosity or make a bold claim)
- Each tweet stands alone but builds on the previous
- Number each tweet (1/, 2/, etc.)
- Final tweet: one clear CTA (follow for more, retweet if useful, or reply with your experience)
- Tone: direct, confident, no fluff`;

          messages: [
            { role: "system", content: "You are a viral Twitter/X thread writer. Format each tweet as: 1/ [content] on its own line. Each tweet must be under 280 characters. Hook must create immediate curiosity." },
