DeepSeek - ChatGPT explained

 

並非誇大。如果你做過這門技術的研究,就會知道製造智能的程式非常艱難。現時OpenAI是最早創新的大模式,它的始創人 Sam Altman 被業界視為神童,各外媒和業者大力鼓吹它。連拜登也認為美國將會領先第四次工業革命,將再雄覇世界。過去兩年間,人們沒有認為這信念是誇大。而且,拜登政府在 AI 領域刻意打壓中國,禁止高端芯片如NVIDIA 的 H100 芯片賣給中國。因為要開發和訓練一個AI 模式需要十萬以上的高端芯片。這制裁將會令中國在AI 領域停頓。


可惜事與願違。有一個無名的中國小子,名叫張文鋒,創立了一間start-up, 只用了550 萬美元,2 千幾個普通的芯片,便劊造出一個AI 模式,而且它在速度和性能遠遠超越世界所有其他大AI 模式。所有AI 業者,學界和整個IT行業甚為驚訝,他們認為不可思議的,因為美國所有大IT 公司如 Microsoft,Google,Meta,Amazon和 OpenAI 皆需要數以十萬計的芯片和億萬元計的投資才可以建造一個可行的AI 大模式,而且他們用了幾年和大量的人力物力,現在卻被一個黃毛小子打敗,而且是遠遠被拋離。

   

這事件有很重大的後果:(1)它證明拜登制裁和打壓中國AI 發展失敗; (2) 中國在AI 領域不是落後於美國,而且將會領先世界;(3) 因為張文鋒的公司DeepSeek和 Alibaba 同時宣布,他們的程式和數字庫是 Open Source, 全世界的 AI 業者皆可以取得和輕易發展,百花齊放,將會令所有美國大IT 公司血本無歸,將來還要對付來自中國和全世界的競爭者;(3) 因為DeepSeek 和 Alibaba 收取用戶的費用很低,大約是OpenAI 所收的百分之一以下,所以,將來在中國民間和工商界,AI 的應用將會飛升,中國,而並非美國,將會領導世界的第四次工業革命 ;(4) Nvidia 的業績成長速度將會降慢,因為現在股民預期它會有高度增長速度,所以它的股價高昂,但當股民認為它的增長速度放慢,它的股價必會下滑。這現象也會發生在 AMD, INTEL, QCOM 身上。所以近兩星期以來,它們的服價下滑。

     

近年美國股市狂飆,原因是股民預期AI 發展將會帶來很多的經濟紅利, 美國將繼續領導世界經濟。現在這個預測看來是過火了。所以,美股將會有可觀的調整。


It's not an exaggeration. If you've researched this technology, you'll know that creating intelligent programs is extremely challenging. Currently, OpenAI is the frontrunner in large-scale innovation. Its founder, Sam Altman, is regarded as a prodigy in the industry, widely praised by international media and peers. Even President Biden believes that the U.S. will lead the Fourth Industrial Revolution and dominate the world again. Over the past two years, this belief has not been considered an exaggeration. Moreover, the Biden administration has deliberately suppressed China's AI development by banning the sale of high-end chips, such as NVIDIA's H100 chips, to China. Developing and training an AI model requires over 100,000 high-end chips, and these sanctions were intended to stall China's progress in AI.


However, things have not gone as planned. A little-known Chinese individual named Zhang Wenfeng founded a startup and, with only $5.5 million and just over 2,000 regular chips, created an AI model that surpasses all other global large AI models in both speed and performance. The entire AI industry, academia, and the broader IT sector are astonished, finding it inconceivable. In contrast, major U.S. IT companies like Microsoft, Google, Meta, Amazon, and OpenAI need hundreds of thousands of chips and billions of dollars in investment to build a viable large AI model, requiring years of effort and immense resources. Yet, this "unknown young upstart" has not only matched them but has left them far behind.


This development has significant implications:

It proves that Biden's sanctions and suppression of China's AI development have failed.

China is not lagging behind the U.S. in AI but is poised to lead the world.

Zhang Wenfeng's company, DeepSeek, and Alibaba have announced that their programs and datasets are open source. This means AI developers worldwide can access and develop them easily, fostering widespread innovation. This will likely cause major U.S. IT companies to suffer immense losses and face intense competition from China and the global market.

DeepSeek and Alibaba charge users a fraction of OpenAI's fees—less than 1%—which will significantly boost AI adoption across China's public and private sectors. Consequently, China, not the U.S., is likely to lead the Fourth Industrial Revolution.

NVIDIA's growth rate is expected to slow down. Its stock price, inflated by investors' expectations of high growth, is likely to drop as growth slows. Similar effects will be seen in AMD, Intel, and Qualcomm stocks, which have already started to decline over the past two weeks.

In recent years, the U.S. stock market has surged due to investor expectations that AI development will yield significant economic benefits and keep the U.S. leading the global economy. However, this forecast now appears overblown, suggesting that the U.S. stock market may undergo a substantial correction.

Food drone delivery in Shenzhen, China

 


Food drone delivery is gaining traction in Shenzhen, China, a city renowned for its innovation and tech-forward culture. Shenzhen has become a hub for the development and deployment of drone technologies, including those used for food delivery. Here's an overview:


Key Highlights

Tech-Driven Environment: Shenzhen hosts some of the world's leading drone manufacturers, such as DJI, making it a natural testing ground for drone-based logistics.


Pioneering Companies: Companies like Meituan, Ele.me, and JD.com are leveraging drones to streamline food delivery services. Meituan, for instance, has successfully implemented drone food delivery routes in select districts.


Operational Routes: Drone deliveries typically serve specific zones, such as business parks or residential communities, where drones can deliver orders to designated pick-up points. This minimizes urban congestion and optimizes delivery times.


Efficiency: Drones can significantly reduce delivery times by bypassing traffic. A typical drone delivery might take 10-15 minutes for a 3-5 km range.


Regulations and Infrastructure: Shenzhen's relatively supportive regulatory environment and dedicated drone logistics routes have facilitated the growth of such services. The city is experimenting with air traffic management systems to ensure safety and efficiency.


Challenges:

Weather Dependency: Drones are sensitive to weather conditions like heavy rain or strong winds.

Payload Limitation: Most food delivery drones have a limited carrying capacity, typically around 2-5 kg.

Regulatory Hurdles: Scaling drone deliveries across the city requires comprehensive regulatory frameworks to address privacy, safety, and airspace management.

Future Prospects: Shenzhen's experience could serve as a model for other cities in China and globally. As drone technology evolves, payload capacity, range, and operational costs are expected to improve, making drone delivery more accessible.


Would you like detailed case studies or insights on specific companies or technologies used in Shenzhen's drone delivery ecosystem?

Shenzhen has emerged as a leader in food delivery via drones, primarily spearheaded by companies like Meituan. These drones are designed to reduce delivery times significantly, typically completing orders within 15 minutes for a 3-kilometer radius, compared to 30 minutes for traditional delivery services. Since launching its drone delivery service in Shenzhen in 2021, Meituan has completed over 184,000 orders, with routes specifically optimized for urban areas​


The delivery process involves the food being transferred to a drone at a nearby “drone-loading site.” The drone then flies to a designated drop-off kiosk, where customers retrieve their orders by scanning a QR code. This system minimizes delivery delays caused by traffic or complex navigation issues. While the service is efficient, it currently requires customers to collect their food from specific pickup points rather than door-to-door delivery​


Shenzhen’s supportive policies and advanced drone manufacturing ecosystem have been key to this development. The city is also promoting drone applications in logistics and other industries, making it a hub for testing and deploying such technologies​

深圳,中国以其创新和技术前沿文化而闻名,食品无人机配送正逐渐在此获得发展势头。深圳已成为无人机技术开发和部署的中心,包括用于食品配送的无人机。以下是概述:


关键亮点

技术驱动的环境:深圳是全球领先无人机制造商的聚集地,如大疆(DJI),使其成为无人机物流测试的天然试验场。


先行企业:美团、饿了么和京东等公司正利用无人机简化食品配送服务。例如,美团已在特定区域成功实施了无人机食品配送路线。


运营路线:无人机配送通常服务于特定区域,如商业园区或住宅社区,无人机将订单送至指定的取货点。这种方式减少了城市拥堵,并优化了配送时间。


高效性:无人机可以通过避开交通显著减少配送时间。通常情况下,无人机配送3-5公里范围的订单仅需10-15分钟。


法规与基础设施:深圳相对支持性的监管环境和专门的无人机物流路线促进了这类服务的增长。该市正在试验空中交通管理系统,以确保安全和效率。


挑战

天气依赖性:无人机对恶劣天气条件(如大雨或强风)较为敏感。

载重量限制:大多数食品配送无人机的载重量有限,通常在2-5公斤之间。

监管障碍:在全市范围内扩大无人机配送服务需要全面的监管框架,以解决隐私、安全和空域管理等问题。

未来前景

深圳的经验可以成为中国其他城市乃至全球的榜样。随着无人机技术的不断发展,其载重量、续航范围和运营成本有望改善,使无人机配送变得更加普及。


自2021年美团在深圳推出无人机配送服务以来,该公司已完成超过18.4万次订单。这些配送路线特别针对城市区域进行优化。


配送流程包括将食物转移至附近的“无人机装载点”,随后无人机飞往指定的投放站点。客户通过扫描二维码取餐。这种系统有效避免了因交通或复杂导航问题造成的延误。尽管服务高效,但目前需要客户前往特定取货点取餐,而不是直接送货上门。


深圳支持性的政策和先进的无人机制造生态系统是这种发展的关键推动力。该市还在积极推动无人机在物流及其他行业的应用,使其成为测试和部署此类技术的中心。
