Instruction tuning unlocks incredible skills in LLMs, but at a cost: they become dangerously overconfident.
You face a choice: a well-calibrated base model or a capable but unreliable instruct model.
What if you didn't have to choose? What if you could navigate the trade-off?

Can AI simulate human behavior? 🧠
The promise is revolutionary for science & policy. But there’s a huge "IF": Do these simulations actually reflect reality?
To find out, we introduce SimBench: The first large-scale benchmark for group-level social simulation. (1/9)
