TypeSafe's Jev AI trades real money with sub-second responses

By PulseAugur Editorial · [1 sources] ·

A new AI model called Jev, developed by TypeSafe, operates as a "System One" model, designed for rapid, structured decision-making rather than text generation. In a 17-day trial, Jev processed market data and executed trades with a median response time of 0.33 seconds and a cost of approximately $0.0002 per query. Despite its speed and low cost, Jev did not demonstrate a trading edge, resulting in a net loss of -4.5R over 15 trades, and its performance mirrored that of a slower LLM agent used in parallel. AI

IMPACT This "System One" AI offers a new paradigm for rapid, structured decision-making, though its initial trading performance did not show a clear advantage.

    17 Days with Jev: I Put a Sub-Second “System One” AI on a Real Trading Account

    <h4>Jev doesn’t write text. It reads a state, answers typed questions and hands back probabilities in a third of a second. Here’s how it works, how to build with it, and what happened when it traded real money next to an LLM.</h4><figure><img alt="" src="https://cdn-images-1.medi…
