How Stale Is Your AI?
Track live release dates and training cutoffs for AI models
How Stale Is Your AI? is a reference tool that tracks the release dates and training cutoffs for 20 current AI models across 8 major labs. It addresses the problem of AI knowledge staleness by providing live counters and exact dates to show how far behind a model's knowledge base is compared to its launch date.
Designed for developers, AI agents, and users who need accurate model information, the tool offers machine-readable data via models.json and llms.txt. It allows AI agents to fetch current release dates and cutoffs directly, preventing them from hallucinating out-of-date version information.
Use Cases
- AI developers checking model training cutoffs
- AI agents verifying model versions via models.json
- Researchers comparing release dates to training cutoffs across labs
- Users checking if an AI model's knowledge is up to date
