Yang Zhilin, the 34-year-old co-founder of the Chinese artificial intelligence firm Moonshot AI, is currently experiencing a surge in recognition. Following the recent introduction of his company's Kimi K3 model, which caused a stir within the AI sector, Yang has been hailed as a "millennial prodigy." However, long before establishing Moonshot AI in China in 2023, Yang pursued his studies in the United States, where he was one of approximately two dozen machine learning Ph.D. candidates at Carnegie Mellon University.

Ruslan Salakhutdinov, a computer science professor at Carnegie Mellon University and Yang's former Ph.D. mentor, shared insights into the qualities that set Yang apart. Salakhutdinov identified four distinctive traits: remarkable independence, innovative thinking, broad technical proficiency, and an ambitious spirit that embraced challenges. These characteristics were evident even in a highly competitive AI program, where Salakhutdinov had also guided other notable researchers who went on to co-found AI startups, achieve professorships at leading universities, or secure research positions at prominent companies such as OpenAI, Anthropic, and Google DeepMind.

Yang's journey from a Ph.D. student to an AI luminary is further illuminated by his academic and professional trajectory. He completed his Ph.D. in an impressive four years, between 2016 and 2019, during which he contributed to the development of the XLNet language model. Salakhutdinov recalled Yang's early conviction, around 2019, that a single, sufficiently scaled AI model could execute diverse tasks through simple natural language commands, a notion that challenged prevailing wisdom at the time. This vision, developed during his internship on Google's AI Brain team, led to co-authorship of significant papers introducing Transformer-XL and XLNet. Furthermore, Moonshot AI's Kimi K3, an open-weight model, has recently been acclaimed for its capabilities in coding, reasoning, and knowledge tasks, attracting considerable attention in Silicon Valley and boosting the company's valuation significantly, demonstrating Yang's unique combination of deep research acumen and hands-on engineering skills.

Yang Zhilin's journey underscores the transformative power of independent thought, technical expertise, and a willingness to venture into uncharted territory. His success with Moonshot AI not only highlights the rapid advancements in artificial intelligence but also inspires a new generation to pursue ambitious goals and challenge conventional wisdom in the pursuit of innovation.

Taco Bell is rolling out a special $1 offer for its popular Enchiritos, a strategic move following a recent cyclospora outbreak linked to its lettuce. This initiative aims to mend customer relations and alleviate public health concerns, especially since the Enchirito is notably free of lettuce. The fast-food chain's stock price saw a dip after the outbreak announcement, prompting this goodwill gesture.

Taco Bell's Strategic Offer Amidst Cyclospora Outbreak

On Wednesday, July 23, 2026, Taco Bell announced a one-day promotion, selling its beloved Enchiritos for a mere $1. This offer is available at participating locations via their app or website, from 8 a.m. to 11:59 p.m. PT. Traditionally priced between $3.99 and $4.29, this significant discount serves as a direct response to a cyclospora outbreak that affected several Midwestern states.

The U.S. Food and Drug Administration (FDA) reported on July 16 that shredded iceberg lettuce supplied by Taylor Farms to Taco Bell establishments in Indiana, Kentucky, Michigan, Ohio, and West Virginia was connected to at least 1,644 cases of cyclosporiasis between May 13 and July 13. This parasite-induced illness, characterized by diarrhea, led to a noticeable decline in customer traffic at Taco Bell and other fast-food outlets heavily relying on lettuce, as indicated by data from Placer.ai.

Following the FDA's announcement, Yum! Brands Inc., Taco Bell's parent company, experienced a drop in its stock price from a five-month high of $167 on July 7 to $147 on July 17. In a bid to restore consumer confidence, Taco Bell's CEO, Sean Tresvant, took to LinkedIn on Tuesday to express gratitude for the unwavering support from the community during this challenging period. He emphasized the company's renewed commitment to prioritizing safety and maintaining transparency regarding future actions and food handling practices.

The outbreak also brought Taylor Farms, Taco Bell's lettuce supplier, under scrutiny for its communication strategy. The company later released a statement acknowledging "significant confusion" and clarified the facts surrounding the outbreak. Public relations experts criticized Taylor Farms' initial handling of the crisis, suggesting it exacerbated the already muddled situation.

This initiative by Taco Bell highlights the delicate balance fast-food chains must maintain between operational efficiency and public health responsibility. The cyclospora outbreak serves as a stark reminder of the critical importance of food safety and transparent communication. Taco Bell's swift response with a customer-centric promotion demonstrates a proactive approach to rebuilding trust and mitigating the financial and reputational damage caused by such incidents. It underscores that in an era of heightened awareness and instant information dissemination, a brand's ability to react effectively and empathetically to crises is paramount.
