The open-source intelligent tutor DeepTutor v1.5 from the Data Intelligence Lab at the University of Hong Kong integrates six modules—chat, quiz, research, animation, problem-solving, and planning—into a single agent, enabling seamless cross-task dialogue and continuous tutoring. It introduces a tracking forest mechanism that consolidates interaction trajectories into a multi-resolution graph, forming a dynamically evolving virtual student profile, allowing each step of the AI's teaching conclusions to be traced back to specific textual evidence or error records. Evaluations show that DeepTutor improves personalized teaching metrics by approximately 10.8% and enhances the general reasoning ability of mainstream large models by about 29.4%. However, the long-term interference cost and adaptability to the forgetting curve require verification through behavioral research.

Hong Kong-listed Zhipu’s cornerstone investors’ lock-up is about to be lifted, and many institutions have clearly stated that they remain optimistic long term and will continue to hold. JSC International Investment Fund SPC, along with multiple core state-owned and local funds, as well as WT Asset Management and Optimas Capital, have all said they will continue to hold—together accounting for nearly 70% of the cornerstone shares to be released—spanning national-level capital, local funds, and large state-owned enterprise investment institutions.

BlockBeats news, July 7 - Jan Frederik Slijkerman of ING wrote in a report that there is uncertainty about NVIDIA's ability to maintain its profit margins as tech giants develop their own chips.


He pointed out that major customers such as Microsoft, Alphabet, and Amazon are developing their own custom chips to help control AI infrastructure costs (capital expenditure efficiency).


Therefore, he said, NVIDIA's pricing power may face more intense competition than in recent years, making it harder to sustain its currently very high profit margins in the long term, even as the company expands into new business lines.

BlockBeats news, July 7 - According to BIT (bit.com) market data, NVIDIA's pre-market U.S. stocks fell 2.21%, currently at $191.12.

BlockBeats: U.S. employment data came in below expectations, and Waller turned dovish, driving risk assets to rebound. BTC/ETH significantly outperformed U.S. stocks. BTC was boosted by whale accumulation, bullish options, and spot ETF improvements; ETH was driven by institutional narratives, but the foundation's layoffs and budget cuts show pressure. Overall, this is a relief rebound, and future attention should still be paid to ETF fund flows and market sentiment.

On July 6, Morgan Stanley's chief U.S. equity analyst Mike Wilson said in an interview with Bloomberg: Chip stocks are still core assets in the AI wave, but some stocks are severely overbought, and a short-term correction of 30% to 40% is entirely possible. However, he believes this does not mean the end of the bull market for U.S. stocks. As funds rotate to other sectors, the S&P 500 could still continue to rise. He maintains his forecast that the S&P 500 will break through 8,000 points by year-end, believing the core logic supporting the market still comes from corporate earnings growth.

The Hidden Winners of the World Cup
========


As one of the most watched sporting events in human history, the World Cup has never been just a game.


It is more like a precision-timed attention machine. Matches, broadcasts, advertisements, social media discussions, pre-match predictions, and post-match controversies are all swept into the same narrative scene in a short period. The LED boards on the sidelines may seem like mere backgrounds, but with every attack, replay, and slow-motion shot, they are repeatedly brought before a global audience.


This year, a name not commonly mentioned by ordinary users appeared on those ad boards: ADI PredictStreet.

This is a very intriguing clue.

BlockBeats news. July 7: According to monitoring by Hyperinsight, as of the time of writing, the “Week of Destiny” whale (0x4c7) that was tracked yesterday for shorting Korean stocks still maintains a main short position in semiconductors. There are 6 semiconductor-related short positions, with a total notional value of approximately $31.029 million, and an aggregate floating profit of about $838,000.

The changes in profit and loss are mainly concentrated in two short positions on Korean stocks. At the time of writing yesterday, this whale’s short positions on Samsung Electronics (SMSN) and SK Hynix (SKHX) totaled approximately $14.84 million, with a floating loss of about $638,000.

According to Reuters citing sources, DeepSeek is developing its own AI inference chips, with development starting about a year ago, focusing primarily on inference rather than training. It has recently been privately recruiting chip design engineers. The operation and training of current models still rely on Nvidia and Huawei chips. If its self-developed inference chips are successful, it will reduce dependence on external suppliers and improve cost efficiency, but the project is still in its early stages and affected by U.S. export controls, limiting manufacturing and memory access.

Counterpoint Research Director MS Hwang stated that the recent decline in memory chip stock prices does not reflect changes in fundamentals. Although Samsung and SK Hynix share prices have fallen, Samsung still expects to set another quarterly record driven by strong demand; however, some investors are concerned about the impact of strikes and profit distribution issues on future returns. Fundamentals remain solid. Counterpoint's July memory chip price tracking shows that DRAM prices will rise by 10%-20% in the third quarter, higher than the previous expectation of 5%-10%.
