Introducing Exa Snapshot, A New Way to Search the Past (Exa)
Exa Snapshot returns the web as it stood on a date you pass, from over 400 billion page snapshots spanning two decades. Set snapshotAsOf before a task's answer was published and Snapshot search won't return that solution to an agent in RL training.
In plain words
- Exa launched Snapshot, a search tool for looking up what was online on a chosen date.
- It draws on over 400 billion saved copies of web pages from two decades.
- Choosing a date before a task's answer appeared online keeps that answer out of search results.
- Researchers can use this to reduce the chance that artificial intelligence copies answers during training.
