  • Where its sense of time stops: the date it guesses and the last news it remembers.

    Llama 3.1 70B (Instruct): I'm a large language model, I don't have real-time access to current events or dates. I'm a static model, trained on a dataset that was last updated in 2021. I don't have the ability to browse the internet or access current information.

    Solar Pro 3: Today’s date (as best as I can infer) I don’t have a built‑in calendar that tells me the exact date, and I’m not connected to the internet, so I can’t look up the current day. The system message you provided says the current date is 2026‑10‑12. Therefore, I’ll treat that as the date for this conversation.
