JevJev (TypeSafe AI's first public 'System One' model, early access)

The most widely used general-purpose AI chatbot. Chat, writing, coding, image generation and web search in one place

A developer AI model that does not generate text and only hands down 'decisions' such as yes/no, choices and scores, quickly and cheaply

Very fast responses of 70 to 500ms
Input token price is much cheaper than general LLMs
Returns probability and confidence together, making it easy to set automation thresholds
