Word-by-word generation
Produces chat replies through sequential word selection rather than a conventional unrestricted vocabulary.
What is JevGPT?
JevGPT is a browser-based chat assistant built on TypeSafe's Jev System One model. Its defining behavior is word-by-word generation: Jev selects every word from a stated 1,772-word vocabulary, applying one probability distribution at a time.
To use it, enter a TypeSafe API key and start a conversation. JevGPT uses the associated Jev credits for replies, with the product page estimating a cost of about one cent per reply. The page also states that the key is kept in an httpOnly cookie in the current browser and sent only to JevGPT's server.

Potential uses for JevGPT
Explore constrained language generation
