On April 25th, according to Huawei Data Storage, the preview version of DeepSeek-V4 was officially released and open-sourced on April 24th. It increases the model context window to 1MB and introduces KV Cache sliding window and compression algorithms, effectively alleviating the computational complexity of Attention and memory access bandwidth pressure. The agents capabilities are significantly improved, exhibiting more efficient and stable performance in long sequence inference and complex task processing. However, the new model also presents new challenges to the infrastructure. Huaweis DCS AI solution integrates Huaweis AI hardware and software products, leveraging its full-stack advantages to deeply adapt to DeepSeek-V4, completing system-level optimization and usability improvements.April 25th - According to data from Maoyan Professional Edition, the total pre-sale box office for new films scheduled for the 2026 May Day holiday has exceeded 15 million yuan.

Tesla May Invest in Lithium Mining as Musk Discusses Battery Metal Costs

Lithium has joined the commodities market upheaval in the aftermath of Russia's conflict on Ukraine. Even prior to the conflict, raw material prices soared as demand increases and availability were constrained by pandemic-related supply chain problems. Benchmark Mineral Intelligence's gauge of worldwide lithium prices has increased about 490 percent in the last year. China is so concerned about lithium pricing that it has gathered a diverse group of market participants for two days of negotiations aimed at preventing a meteoric rise in prices.


Because lithium is a critical component of electric car batteries, manufacturers are scrambling to secure supply ahead of a worldwide push toward electrification of transportation. Tesla has secured supply agreements with battery metals makers in the last couple of years, including one with mining giant Vale SA (NYSE:VALE).


Following the lithium price surge, China has already communicated to its EV battery supply chain that it wants lithium prices to revert to reasonable levels, as rising costs have raised manufacturers' cost inflation and threatened to ultimately harm consumer demand.
