In this article, Tian Yuandong provides profound insights into several key issues in current AI research, particularly his skepticism towards the Scaling Law and his advocacy for generative AI.

Tian first discusses the limitations of the Scaling Law. Proposed by OpenAI in 2020, the Scaling Law suggests that the ultimate performance of large models is primarily determined by computational power, model parameter size, and the amount of training data, rather than the specific structure of the models. However, Tian points out that as model performance approaches human levels, acquiring new data becomes increasingly difficult, and further improvements become harder to achieve. Additionally, he highlights that many real-world long-tail needs involve scenarios with very little data, which cannot be addressed by relying on the Scaling Law alone. This could eventually lead to a situation where everyone is isolated on their own "data islands," unable to share and utilize each other's data.

Tian then emphasizes the advantages of generative AI. He believes that generative AI can generate large amounts of content from minimal prompts, reducing the need for manual input and repetitive labor. Generative AI can work similarly to teaching a child, where minimal guidance allows it to extrapolate and create more, significantly boosting productivity. This is because generative AI can work around the clock, has low replication costs, and replicating engineers is very difficult.

Furthermore, Tian presents his views on breakthroughs in data efficiency. He argues that achieving truly data-efficient artificial general intelligence (AGI) requires 2-3 major breakthroughs. While the Scaling Law may be effective in some aspects, it is not the complete solution, as it represents a very pessimistic future.

Regarding the interpretability of AI, Tian believes that AI models based on neural networks are interpretable, and eventually, humans will understand how these models are trained. Despite many currently inexplicable aspects, he argues that this should not be a reason to abandon exploration.

Lastly, Tian discusses the diversity of technology in Silicon Valley, noting that everyone has their own methods, and technological progress does not necessarily rely on current mainstream approaches. Non-mainstream explorations could potentially drive the next technological revolution. He also suggests abandoning the notion that "the brain is the controller of humans," asserting that every part of the body has a vote in behavioral expressions, and future integrated AI will have a vote as well.

Through Tian Yuandong's perspective, this article offers readers unique insights into the development of AI, the limitations of data-driven models, and the prospects of generative AI, making it a valuable read for deeper understanding and contemplation.

In recent years, with the rise of large Transformer language models such as OpenAI's ChatGPT and Meta's LLaMA, the field of open-domain language generation has attracted increasing attention. This article provides a detailed introduction to several major sampling strategies and their implementation methods in the Transformer library, including greedy search, beam search, top-K sampling, top-P sampling, and temperature adjustment.

Greedy search generates text by selecting the word with the highest probability at each step, which is simple but prone to repetition. Beam search retains multiple candidate sequences, reducing the risk of missing high-probability words, but it does not guarantee finding the optimal solution. Top-K sampling chooses from the top K words, increasing the diversity of generated text, but the fixed K value may not be suitable for all situations. Top-P sampling dynamically adjusts the sampling pool through cumulative probability, making it more flexible and effective. The temperature parameter affects the output of the softmax function, controlling the randomness and creativity of the generated text.

Each of these strategies has its own advantages and disadvantages. Understanding and selecting the appropriate strategy can significantly improve the text generation quality of language models.

This article provides an in-depth analysis of the background, impact, and future trends of the current large model price war. Since DeepSeek’s price cut, major companies such as ByteDance, Zhipu, Alibaba, and others have followed suit, triggering a wave of price reductions, even offering models for free under certain conditions. The primary goal of these price cuts is to attract developers by lowering trial costs and promoting cloud and other product sales. The article points out that despite the widespread attention from the big companies' price cuts, model startups are not panicking because these cuts have many conditions, and the actual usage costs have not significantly decreased.

Performance remains a key factor for developers, and the price war has limited actual impact on them. What really matters is the model's performance and business risk. The article also mentions, "Regardless of whether it’s for large companies or model startups, reducing Token costs is an inevitable trend," indicating that future Token prices may become negligible, fostering the prosperity of the large model ecosystem and benefiting companies along the industry chain.

Future business models may evolve in two paths: serving customers for free to achieve large scale or charging users directly to achieve high profitability. As the article states, "The aggressive cloud vendors' intentions are obvious: to attract a large number of trial developers by lowering trial costs; to enhance cloud and other product sales by reducing model costs."

In summary, while the price war brings challenges, it also offers more opportunities and market education for the industry. Model vendors need to continuously innovate in technology and business models, reduce costs, and improve performance to remain competitive.

This article provides a detailed introduction to five simple and effective methods to enhance thinking abilities. Here are the specific methods:

1. Sequence Recall Method: This method involves recalling the content you have read or watched after a certain interval to train memory and information retention. For example, after reading several articles or watching several videos, take a break and then try to recall the order and key points of these contents. The key points of this method are to recall after a certain interval, avoid looking at the answers, and try to recall in order.

2. Feynman Learning Technique: This technique involves deepening understanding by simulating explaining new knowledge to others. The specific steps include explaining the core content of the knowledge point (what it is), describing its background and purpose (why it is), and summarizing its application (how to do it). This method helps to reinforce understanding of the knowledge, making it better absorbed and internalized.

3. Structured Thinking Method: This method helps in organizing thoughts and expressing viewpoints more clearly by clarifying points, reasons, and evidence. Specific training methods include briefly summarizing the viewpoint, listing the reasons supporting the viewpoint, finding evidence for each reason, and integrating them into a complete argument. This can make expressions clearer and logic more rigorous.

4. Sensory Immersion Method: This method involves focusing attention on sensory experiences to enhance concentration. It is suggested to choose a quiet outdoor environment and concentrate on sensory experiences such as sight, hearing, and smell, avoiding analysis or thinking. This can effectively improve perception of the current environment and enhance the focus of attention.

5. Pre-Sleep Guidance Method: This method suggests reviewing interesting and valuable experiences of the day before sleep, avoiding the repeated recall of negative information to optimize memory. The specific approach is to review and record positive and meaningful events that happened during the day before going to bed every night, strengthening the brain’s memory of these positive information while avoiding recalling negative events to maintain a positive mindset.

The article not only provides detailed steps and usage tips for each method but also encourages readers to integrate these methods into their daily lives gradually forming habits, thereby achieving comprehensive enhancement of thinking abilities.
