Yiliahua: Fusaka Upgrade Causes Ethereum Gas Fee Spike, Due to EIP-7918 Introducing Fee Floor

Beating AI Express: Google DeepMind has launched its next-generation flagship model, Gemini 4 Argon. Designed for long-horizon complex tasks, it covers software engineering, finance, legal work, and cybersecurity. The model is not yet available to general users; initially, it will only be provided to trusted cybersecurity teams via the Fairwind Program, with plans to gradually roll out access to paid API clients and Google AI Ultra users later. One of Argon’s key upgrades is its output length: the single-turn output limit has been raised from the previous 64K tokens to 1 million tokens, enabling the model to sustain reasoning and execute longer steps in a single task. Google says it has already used the model internally for large-scale code migration, algorithm optimization, and data center memory optimization. In official evaluations, Argon scored 77.9% on DeepSWE v1.1, outperforming GPT-6 Astra (74.1%) and Claude Opus 5.5 (74.2%). It also ranked first on the Vals Index and AutomationBench. However, it is not fully leading: on FrontierSWE, Terminal-Bench 4.0, and some scientific tasks, it still lags behind GPT-6 Astra or Claude Opus 5.5. Google has also significantly strengthened its cybersecurity capabilities: Argon can automatically discover, verify, and patch software vulnerabilities. The version provided to trusted defense teams even removes some cybersecurity restrictions to unlock its full functionality. Ahead of full launch, Google is continuing to test risks including abuse, prompt injection, and agent overreach. During the initial API rollout, pricing will be $2 per million input tokens and $10 per million output tokens, with prices later doubling to $4 and $20 respectively.

MetaMask has released a security update on X, disclosing that some of its infrastructure has been impacted by a security incident. No signs of direct threats to MetaMask wallets have been detected so far. As a preventive measure, MetaMask stated that it is coordinating with relevant clients, partners, and security advisors to proactively exit affected validators in its non-custodial staking business, and will announce further progress at an appropriate time. MetaMask emphasized that this incident relates to infrastructure and does not represent current security risks for MetaMask wallets.

Aave founder Stani posted a statement saying his team is collaborating with Lido to monitor the progress of the recent security incident affecting MetaMask Staking infrastructure. Stani added that the Aave market has not been impacted, with all operations running normally.

Goldman Sachs said Wednesday’s U.S. inflation data, paired with New York Fed President John Williams’ comments yesterday, has led the firm to now view an October Federal Reserve interest rate hike as unlikely. Economists Jan Hatzius, David Mericle, and Alec Phillips noted in a research report that, based on the latest inflation data, they project fourth-quarter core PCE year-over-year growth will reach 3.0%, well below the 3.4% median forecast from FOMC participants. The bank has thus pushed back its expectation for a second rate hike to December, and believes the FOMC has a high likelihood of ultimately determining no further rate increases are needed.

The yield on the US 10-year Treasury note rose to 5.29%, hitting a new high since 2007.
