Pangram融资900万美元推进AI内容检测技术

纽约AI检测初创公司Pangram宣布完成900万美元融资，由Menlo Ventures领投，Haystack、ScOp、Script Capital和Cadenza等机构参投1。该公司致力于区分人类生成内容与AI生成内容，以应对互联网上日益泛滥的AI垃圾内容问题1。

本轮融资的同时，Pangram推出了下一代产品矩阵，包括文本检测模型Pangram 4和图像检测模型Pangram Image1。其中Pangram 4的文本检测准确率超过99%，误标率约为每1万份人类文档中有1份被错误标记为AI生成1。该公司通过API服务向Substack、Quora、学校、大学、出版商和招聘人员等客户提供服务，同时提供月度订阅服务，订阅价格为每月20美元1。

Pangram由Stanford大学AI和机器学习专业毕业生Max Spero和Bradley Emi创立，公司成立于约两年前1。

Pangram, a New York-based artificial intelligence detection company, has raised $9 million in a funding round led by Menlo Ventures, with participation from Haystack, ScOp, Script Capital, and Cadenza 1. The startup, founded approximately two years ago by Stanford AI and machine learning graduates Max Spero and Bradley Emi, aims to distinguish between human-generated and AI-generated content as artificial content proliferates across the internet 1.

Alongside the funding announcement, Pangram unveiled two new detection tools: Pangram 4, its next-generation AI text detection model, and Pangram Image, designed for detecting AI-generated images 1. The text detection model achieves accuracy exceeding 99 percent, with a false positive rate of approximately one in 10,000 human documents incorrectly flagged as AI-generated 1. The company offers a subscription service priced at $20 per month 1.

Pangram's API has already attracted a diverse clientele including Substack, Quora, educational institutions, universities, publishers, and recruitment professionals 1.
