Tavus推出了Griffin，该公司称之为首个“人类交互模型”（HIM），这是一类旨在实时理解并进行面对面对话的模型。Griffin在处理视频接收与生成的过程中，能够解析语音、面部表情、语调、手势以及停顿。

在Tavus的一项研究中，经过一分钟的视频通话后，有48%的参与者认为Griffin是真人，而以往的系统最高仅为2%。在Tavus描述的独立Nvidia测试中——该测试衡量AI在直接音视频对话中给人的“人性化”程度——Griffin获得了3.83分。实际人类得分为3.92，此前表现最佳的AI模型得分为2.80。

名为Griffin-Lite的预览版已作为“研究预览”提供给“特定测试人员”，而功能更强大的版本将在“解决安全担忧后”推出。Tavus列出的潜在用例包括辅导、练习困难对话以及基于摄像头的技术支持。

这家位于旧金山的AI初创公司成立于2020年，已筹集约6400万美元。它最初为销售和营销领域构建个性化AI视频，随后扩展到与数字人进行实时视频对话。有关Griffin的更多详情请参阅Tavus研究报告。

Tavus has introduced Griffin, what the company calls the first "Human Interaction Model" (HIM), a class of model designed to understand and carry on face-to-face conversations in real time. Griffin processes speech, facial expressions, tone of voice, gestures, and pauses while both receiving and generating video.

In a Tavus study, 48 percent of participants believed Griffin was a real person after a one-minute video call. Previous systems maxed out at two percent. In what Tavus describes as an independent Nvidia test measuring how human an AI feels in direct audio-video conversation, Griffin scored 3.83 points. Actual humans scored 3.92, the previous best AI model hit 2.80.

A preview called Griffin-Lite is available to "select testers as a research preview," with a more capable version coming once "safety concerns are addressed." Tavus lists tutoring, practicing difficult conversations, and camera-based tech support as potential use cases.

The San Francisco AI startup was founded in 2020 and has raised about $64 million. It started out building personalized AI videos for sales and marketing, then expanded into live video conversations with digital personas . More details on Griffin are in the Tavus research report .
