Show HN: How Stale Is Your AI? Release age and training cutoff for 20 models

A tracker comparing 20 AI models across 8 labs reveals significant gaps between when models are released and when their training data ends, with some models already months or years behind at launch. Only 9 of the 20 models have published training cutoff dates, and web search capabilities don't address staleness since models don't retain information between conversations. The data shows that release date and training cutoff are two separate measures of how current an AI model actually is.
