Max tokens per user message in ChatGPT (Pro) for GPT-4.1 mini is 129,024 (though I only got it working with ~117k), and for GPT-4.1 it's 34,815 - max context length is apparently just ~128k tokens though?

Viral score

Based on absolute engagement — the platform doesn’t expose follower counts here, so large accounts score higher.

From likes, comments.

Why it worked

Opens with a short, self-contained line that is easy to take in at a glance.
Uses concrete numbers instead of vague claims, which makes it credible and quotable.
Points at real customers, users or results as evidence rather than assertion.
Ends on a question, which is the most reliable way to turn readers into repliers.
The opening line stands alone, so it reads completely before the post is expanded.
Written from experience rather than as advice, which is harder to argue with.

The mechanics

Hook: Plain observation
Structure: Hook → Invitation
Style: Conversational paragraphs at a steady pace.
Tone: personal, concrete
Mechanisms: Specificity, Social proof
Written for: People building with AI
