Jev 在交易系统中的定位：决策层而非预测器
一位交易者澄清 Jev 的适用边界：它适合做高吞吐分类、agent 路由和盘前风控闸门，不适合当独立的价格或事件概率预言机。
Seeing a lot of AI slop out there around building a trading system with Jev. As usual, these articles way off point. Jev is not a replacement for your trading agent or a frontier LLM probabilistic forecaster. It is a fast, cheap decision layer that returns typed probabilities over fixed choices (Choice / Score / Noul). Excellent for high-volume classification of filings, news, and transcripts, for routing steps inside an agent, and for pre-trade risk gates. It is weak as a standalone price or event probability oracle. Public tests show it compresses forecasts toward 50% and loses to the market itself when asked to price contracts blind. Use it to extract structured features and enforce policy. Keep your edge research, sizing, and execution in code and stronger models.
