For the web version’s accuracy, I tested different feature limits. I prioritized performance and kept 500k features—stored as JSON, it’s 107MB (though gzip on server reduces it to ~38MB). I tried smaller versions (50k, 80k)—accuracy only dropped 3–4%, but final AI detection rates varied significantly, especially for human texts, with relative errors up to ±50%, leading to false positives. So I stuck with 500k.
After a calm Monday, US stocks fell sharply after trading opened on Tuesday, with the Dow dropping more than 2% before paring back those losses to settle about 1.2% down.
