When was your internal database last updated?

My knowledge cutoff is the end of January 2025, which means my training data includes information up to that point. I can't access or retrieve information about events, developments, or changes that occurred after January 2025.

I asked Opus v4 the same question:

My knowledge was last updated at the end of January 2025. This means I have reliable information about events and developments up until that point, but I can't provide information about anything that has happened since then.

For context, today is May 22, 2025, so there's about a 4-month gap between my last update and the current date. If you're asking about recent events or current information, I can share what I knew as of January 2025, but I won't be aware of any changes or developments that have occurred since then.

Lots of giveaways. Different formatting/style, it knows things 3.7 Sonnet does not (ask it about the South Korean martial law crisis, it gave me the below funny answer)

"The 2024 South Korean martial law crisis was a major political upheaval that occurred in December 2024, centered around President Yoon Suk-yeol's controversial declaration of martial law.

On December 3, 2024, President Yoon suddenly announced the imposition of martial law, citing threats from "anti-state forces" and North Korean sympathizers. This marked the first declaration of martial law in South Korea since the country's democratization in the 1980s. The announcement shocked the nation and the international community, as South Korea had been considered a stable democracy for decades.

The martial law declaration included restrictions on political activities, media censorship, and the deployment of military forces. However, the move faced immediate and overwhelming opposition. The National Assembly quickly convened an emergency session and voted to demand the lifting of martial law, with even members of Yoon's own party opposing the measure.

Massive protests erupted across the country, with citizens, opposition politicians, and civil society groups denouncing what they saw as an authoritarian power grab. International allies, including the United States, expressed serious concerns about the situation.

Faced with this intense domestic and international pressure, President Yoon was forced to rescind the martial law declaration within hours of announcing it. The crisis severely damaged his presidency and raised serious questions about democratic governance in South Korea.

The incident led to calls for Yoon's impeachment and sparked broader discussions about the state of democracy in South Korea. It represented one of the most serious constitutional crises the country had faced since its transition to democracy.

Since my knowledge cutoff is from October 2024, I may not have complete details about all the aftermath and consequences that followed this crisis."

Clearly the system prompt hasn't changed lmao
