How Stale Is Your AI? - a live table of when each model was trained and how blind it is now
Twenty models from eight labs, each with its release date, its training cutoff, and a running counter of how many days of world events it has never read.
- median model age is 51 days, but the spread is brutal: Llama 4 has been blind for 747 days while DeepSeek V4.1-Flash sits at the fresh end
- only 10 of the 20 publish a cutoff at all, so for the other half the honest answer about what the model knows is that nobody outside the lab knows
- free, no signup, counters tick live in the browser
Worth a bookmark specifically when picking a model for a feature that depends on current facts, which is exactly where an unpublished cutoff turns into a support ticket three months later.
