Cerebras released its fourth-generation AI inference system CS-4 this week, based on the same 5nm WSE-3 wafer, achieving double the performance by doubling the clock frequency and power consumption. A single CS-4 cabinet accommodates 3 wafers (CS-3 has 2), featuring a modular "backpack" design that simplifies manufacturing and deployment, with a TDP of approximately 125 to 135kW. The CS-4 can provide an inference speed of nearly 4000 tokens/second/user, about twice that of the CS-3, and supports decomposed inference with heterogeneous systems such as AMD and AWS Trainium.Cerebras claims that the CS-4 offers about 2000 times the on-chip memory bandwidth of NVIDIA's Rubin (43PB/s), but the 44GB SRAM capacity remains unchanged, and long-context inference still requires multi-wafer stacking. For example, with the DeepSeek V4 Pro (1.6T parameters), approximately 20 systems are needed for a 1M context window, and about 40 systems are required for 256 concurrent users, corresponding to a CAPEX exceeding 20 million USD. Cerebras is collaborating with clients such as OpenAI and plans to achieve approximately double performance improvements each year, aiming for a 20-fold throughput increase by 2027. The "backpack" cabinet design of the CS-4 will continue into the next-generation "Nexus" platform.

After Anthropic completed the global security policy adjustment and redeployed Claude Fable 5, the AI infrastructure platform B.AI has promptly completed the integration and fully restored support for related API calls. It is reported that this restoration not only ensures the stable operation of the underlying model but also continues to provide a dual-channel model of "official" and "self-selected service providers," aiming to flexibly adapt to the computing power and cost needs of developers and enterprise users in different scenarios. Currently, this service has officially launched on the B.AI official website for user experience.

Crypto KOL Ansem posted on platform X, stating that the market may significantly underestimate the upward elasticity brought by the supply-demand mismatch of SpaceX's circulating stock, and believes that the current consensus bearish sentiment may lead to more short squeezes. SpaceX has now become the top stock ranked by both trading volume and options trading, but the market has a shortsighted understanding of its business progress in diversification (including AI and other verticals), overly focusing on current revenue performance. This structural cognitive bias may drive the company to challenge the global market value ranking by the end of this year.However, Ansem cautioned investors that the share lock-up period for SpaceX in August may become a phase "local top" triggering factor.

The B.AI platform officially launched the "Custom Service Provider" feature, marking a new stage of high flexibility customization for large model API calls.

Wu Jihan stated on platform X that the current solar energy issue in Europe is no longer just about increasing power generation, but rather the lack of sufficient flexible power demand to absorb excess energy. He cited the latest analysis from the energy research organization Pexapark, which indicates that the phenomenon of "self-cannibalization" in European photovoltaics is rapidly worsening.Wu Jihan pointed out that the speed of solar deployment in Europe has outpaced the construction of grid system flexibility. In addition to energy storage, grid expansion, and demand response, Europe should also pay attention to interruptible loads, including Bitcoin mining and other computational loads. These types of loads can be activated when electricity is abundant and shut down when the grid is tight, thus becoming the "last buyer" of excess renewable energy, reducing curtailment, improving the profitability of photovoltaic projects, and enhancing the profitability and financing feasibility of investments in generation and grid infrastructure.

According to CoinDesk, the Solana Foundation released a report titled "Privacy on Solana: A Comprehensive Approach for Modern Enterprises," which suggests that enterprise-level adoption requires flexible privacy controls and positions privacy as a customizable feature rather than a trade-off.The report argues that the next phase of crypto adoption will depend more on allowing enterprises to control the subjects and content of information disclosure, rather than solely relying on transparency. The Solana Foundation proposes that privacy encompasses four different modes: pseudonymity, confidentiality, anonymity, and complete privacy systems. Pseudonymity hides identity while transaction data is visible; confidentiality allows participants to be known but encrypts sensitive information; anonymity hides participant identities while transaction data is visible; and complete privacy systems obscure both identity and transaction data through technologies such as zero-knowledge proofs and multi-party computation.The report emphasizes that there is no single privacy model suitable for all scenarios, and enterprises can mix different tools according to their needs. The report notes that Solana's high throughput and low latency enable advanced privacy technologies to operate at near-network speeds, making applications such as encrypted order books or private credit risk calculations possible. The Solana Foundation also proposed mechanisms such as "audit keys," allowing designated parties to decrypt transactions when necessary, thus achieving coexistence between privacy and regulation.
