3/ The results? Our 3B Time-R1 outperforms models over 200 times its size (like the 671B DeepSeek-R1) on highly challenging future event prediction & creative scenario generation tasks! This shows smaller, efficient models can achieve superior temporal performance.

1/ Why do LLMs often falter with time? 🤔 Key issues include: .➡️ The static nature of their training corpora, which inevitably become outdated. ➡️ Non-chronological training processes, where temporal info is handled out of sequence, hindering robust event-time logic.
