Bitcoin Exchange Coinbase Secures Mythos AI With 83.1% Score

Crypto News

Coinbase, a major Bitcoin (BTC) exchange, has secured access to Anthropic’s restricted Claude Mythos Preview model, making it one of the first crypto firms inside the developer’s Project Glasswing defense program. Chief Information Security Officer Jeff Lunglhofer said the company will deploy the model to strengthen protections across internal systems and the open-source software embedded in its trading and custody infrastructure. The deployment is a defensive operational upgrade rather than a consumer-facing feature such as an AI trading bot. Mythos is designed for advanced vulnerability discovery, and Anthropic has limited access because it believes the model now outperforms most humans at finding and exploiting software flaws. Anthropic said Mythos identified thousands of previously unknown zero-day defects across major operating systems and browsers within weeks before its April 7 Glasswing announcement. It cited a 27-year-old OpenBSD weakness and a 16-year-old FFmpeg defect found largely autonomously. On the CyberGym vulnerability-reproduction benchmark, Mythos scored 83.1%, ahead of the 66.6% recorded by Claude Opus 4.6. Glasswing initially included AWS, Apple, Google, Microsoft, Nvidia and JPMorgan Chase, with Anthropic also extending access to more than 40 organizations maintaining critical software and up to $100 million in usage credits. The move places a crypto venue alongside major technology and financial institutions already in the program, signaling that exchange security is becoming an early deployment ground for frontier AI models. For Coinbase, the tool addresses a direct risk. In May 2025, the exchange disclosed that a foreign support contractor was bribed, exposing some customer names and contact details, while the company rejected a roughly $20 million ransom demand and offered an equivalent bounty. The new access could allow deeper audits than public models permit. After the research preview, Anthropic plans pricing of $25 per million input tokens and $125 per million output tokens, paired with safeguards intended to block dangerous outputs from future Claude Opus releases.

U.S. and U.K. regulators are moving to align digital-asset rules after the U.S. Treasury published an Aug. 4 joint statement summarizing the July 8 London meeting of the two countries’ financial regulatory working group. Senior officials from the Treasury, Bank of England, Federal Reserve, U.K. Financial Conduct Authority and other U.S. agencies reviewed crypto frameworks, payment modernization, financial stability, artificial intelligence, capital markets and bank supervision. The U.S. side reported progress implementing the GENIUS Act for stablecoins and gave an update on digital-asset market structure, while the U.K. outlined its wholesale financial markets digital strategy and named Christopher Woolard as its wholesale digital markets advocate. A separate joint stablecoin statement supports cross-border use and comparable treatment for similar risks, requiring money-issued stablecoins to hold at least 1:1 reserves in high-quality liquid assets. The approach distinguishes reserve-backed payment tokens from algorithmic stablecoins, which rely on supply rules rather than segregated assets. The FDIC has proposed standards covering reserves, redemption, capital, liquidity, risk management and custody, including a two-business-day redemption expectation for bank issuers. The statement follows July 14 recommendations from the Transatlantic Taskforce for Markets of the Future, calling for less unnecessary cross-border friction, stronger supervisory cooperation and clearer treatment of tokenized financial activities. The U.K. is pursuing tokenized wholesale markets, where blockchain records can represent securities, deposits or collateral, and the FCA is developing a unified scheme to improve post-trade processing, collateral mobility and interoperability. A 54-company industry initiative includes BlackRock and JPMorgan, while the Bank of England has drafted requirements for systemically important stablecoins, including a temporary £40 billion issuance cap for each qualifying token and unlimited user access. For Bitcoin and major altcoin markets, the practical effect is likely to be clearer institutional rails rather than immediate product approval. The working group is expected to meet again in early 2027 under a semiannual dialogue established in 2018.

COINOTAG’s analysis is that both developments point to the same phase: crypto infrastructure is being hardened at the operating layer rather than marketed through consumer surfaces such as an AI crypto wallet. The primary source is the U.S. Treasury’s Aug. 4 joint statement, which records regulator coordination on stablecoin frameworks and market structure, and the FDIC’s proposed GENIUS Act standards, which remain a proposal rather than a final rule; no final effective date has been set. If adopted, those standards would bind regulated payment-stablecoin issuers with 1:1 reserves and two-business-day redemption expectations. Together with Anthropic’s restricted model access, this signals that security, custody and redemption operations are becoming the sector’s regulatory and technological battleground.
