first_img Tavus claims that the Griffin model causes 48% of video call participants to mistakenly believe they are interacting with a real person

AI startup Tavus released a new model called Griffin on October 1, referring to it as the first "human interaction model" that can understand and generate face-to-face conversations, paying attention not only to wording but also to expressions and pauses. Tavus stated that in tests, after a one-minute video call with Griffin-Lite, 26 out of 54 participants (48%) believed the other party was a real person; its previous generation system only convinced 1 out of 41 participants.Participants were told they would have a one-minute video call with another person to discuss things they were looking forward to this year, and only at the end of the call were they asked if they suspected the other party was not a real person. Tavus noted that those who became suspicious typically noticed within 20 seconds. This result comes from Tavus's own research page, where participants were recruited through a channel they call an independent research platform. Community comments on X pointed out that these results have not been independently verified and do not meet standard protocols.In the NVIDIA VideoFDB benchmark, Tavus claimed Griffin-Lite ranked first, with a generation dimension score of 3.83, the next best system scoring 2.8, and human reference scoring 3.92; the perception dimension score was 3.73, with the strongest baseline at 3.44 and human reference at 4.2. Tavus stated that NVIDIA independently conducted this evaluation. Griffin supports full duplex, allowing it to listen, see, and speak simultaneously, with an average audio-video delay of 0.43 seconds on the NVIDIA H100 chip. Tavus completed a $40 million Series B funding round led by CRV in November 2025.

first_img BNY is in talks with Kraken's parent company Payward for infrastructure cooperation

According to CoinDesk, informed sources revealed that the custody bank giant BNY is in talks with Payward, the parent company of the cryptocurrency exchange Kraken, for a broad collaboration covering digital assets and financial market infrastructure. The potential agreement may involve areas such as crypto products, custody, wealth management, trading, payments, and infrastructure, with related services provided through Payward Services, which targets banks, exchanges, and asset management institutions.One source indicated that part of the proposed collaboration may be similar to the infrastructure component of the recent agreement Payward reached with Nasdaq. Negotiations are still ongoing, and there is no guarantee that an agreement will be reached; both Payward and BNY declined to comment. BNY, formerly known as Bank of New York Mellon, provides custody, asset services, clearing, and wealth management services to institutional clients and has been developing tokenized deposits to support near real-time on-chain settlements among institutional market participants.Reaching an agreement with BNY would further promote Payward's efforts to connect digital asset businesses with traditional financial institutions. Last month, Nasdaq Ventures agreed to invest $100 million in Payward at a valuation of $21 billion, expanding the collaboration between the two parties in tokenized stocks. Under the agreement, both parties will continue to develop the operational and commercial infrastructure for Nasdaq stock tokens, and Payward will also adopt Nasdaq's market surveillance technology in its cryptocurrency, stock, tokenized stock, futures, and options trading venues, with both parties expecting to launch Nasdaq stock tokens in the second quarter of 2027.
