Opus 5.5 did this in 5 minutes
This is INSANE 🫣 Comment 'Prompt'
Wonderful! 5 artificial intelligence models were asked to design a durable bridge with a 3D printer.
🪙 Claude Opus 5.5: 59 kg 2️⃣ Meta Muse Spark 1.3: 12 kg 3️⃣ GPT-6 Astra: 8 kg ❌️ Grok 4.7: The bridge could not stand. ❌️ Some K3: The bridge could not be assembled.
5 top models got one task: design, engineer, and 3D print a bridge that holds the most weight possible — and the gap between the results was massive
The rules were identical for everyone: a 2-foot span, a max of 500 grams of filament, printing under 18 hours, with a fixed load
Most AI agents don't fail at the task.
