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 Sky Protocol received a S&P B- rating, with a reserve target of 150 million USD and a stable asset ratio of 50%

S&P Global Ratings confirmed on October 1 that the issuer credit rating of the stablecoin protocol Sky Protocol is B-, with a stable outlook. S&P stated that Sky is advancing the Prime Agent ecosystem (formerly Stars or subDAO), which includes strategies such as over-the-counter lending with a scale of approximately $1 billion, accounting for about 10% of the total assets supporting USDS and DAI; these semi-independent entities use the Sky balance sheet for specialized investments within the risk parameters set by governance, while increasing management and monitoring complexity.The total supply of USDS and DAI increased from $7.7 billion in August 2025 to $9.5 billion. As of September 17, 2026, reserves are approximately $92 million, with a target of $150 million. Robust assets USDC and tokenized money market funds backed by government bonds total approximately $4.92 billion, accounting for about 50% of circulating USDS and DAI, up from 36% in August 2025. On-chain crypto lending has decreased to about 25% of the balance sheet, while over-the-counter crypto lending has increased to approximately $1 billion. Newly included assets include RLUSD, PYUSD, and USDG totaling approximately $392 million, as well as a tokenized fund investing in AAA-rated CLO shares of about $500 million.As of September 2026, the four major Prime Agents account for approximately 65% of the combined assets, with Spark accounting for 36%, Grove for 24%, Obex for 4%, and Osero for 1%.

first_img Cboe is exploring the launch of VIX perpetual futures, still in the early stages

According to CoinDesk, Cboe is exploring the launch of perpetual futures linked to the VIX index, which is still in the early stages, with no contract specifications yet and no filing documents submitted. This news comes from Bloomberg.The VIX index measures the expected volatility over the next 30 days as reflected by the pricing of S&P 500 options. As investors buy options to hedge against sharp market declines, the demand for options during downturns surges, thereby raising the index, which is why it is regarded as Wall Street's "fear gauge." Perpetual futures were first proposed by economist Robert Shiller in 1993 and were subsequently commercialized by the cryptocurrency industry.A mature derivatives ecosystem has already formed around the VIX, covering futures, options, and exchange-traded products tracking the index. However, futures come with expiration dates, and when contracts terminate, traders must roll over their positions or shift their bets to the next available contract. This rolling operation is costly and erodes returns, which was a major criticism faced by Bitcoin futures ETFs when they debuted at the end of 2021.In contrast, perpetual swaps never settle and instead anchor contract prices to the spot index through a funding rate mechanism, theoretically providing investors with the closest investment channel to the actual VIX spot price. Martin Lee, Head of Market Insights at DWF Labs, told CoinDesk that traders do not need to worry about expiration and value decay, as they can focus solely on assessing the direction of the underlying asset. He expects a strong trend of "perpetualization" to emerge in the coming months.

first_img The United States has designated the Russian A7 Network as a transnational criminal organization and plans to cut off its cryptocurrency funding channels

According to Decrypt, the U.S. Department of the Treasury's Office of Foreign Assets Control has designated the Russian shadow banking network A7 Network as a significant transnational criminal organization, listing its relevant addresses in Russia, Kyrgyzstan, Nigeria, and Zimbabwe. The Financial Crimes Enforcement Network has proposed a draft rule that aims to prohibit U.S. institutions from participating in any fund transfers involving the network's "sub-agent companies," covering convertible virtual currencies and not limited to fiat currencies, which is expected to affect approximately 348,000 institutions, including several cryptocurrency exchanges.The proposal is based on six special measures granted by Section 9714 of the Countering Russian Money Laundering Act, ultimately selecting the sixth measure, which is the fund transfer ban. The fifth measure, which restricts correspondent accounts, is considered to have loopholes: research by blockchain intelligence firm TRM Labs shows that A7A5 transactions completely bypass the correspondent banking system, which the Financial Crimes Enforcement Network views as a core aspect of its business model. A7A5 is a ruble-backed token issued by Old Vector, registered in Kyrgyzstan, operating on Tron and Ethereum, with reserves held at the Russian state-owned defense bank Promsvyazbank.The Financial Crimes Enforcement Network stated that between February 2025 and June 2026, over 180 entities handled at least $17.91 billion in A7A5, which historically circulated almost entirely through the sanctioned exchanges Garantex and Grinex, often used as a non-frozen bridge to convert into USDT and then into fiat currency.
