LLMs Flunk Basic Math: 9.11 > 9.9

Major language models have collectively flunked a basic math test. Recently, veteran prompt engineer Riley Goodside uncovered a glaring flaw: when asked a simple numerical question, a string of leading LLMs — including GPT-4o, Google Gemini Advanced, and Claude 3.5 Sonnet — spit out the wrong answer. These models incorrectly insisted that 9.11 is larger than 9.9. Despite the obvious error, they offered plausible-sounding justifications.

Curiously, when the order of the numbers was reversed, the same models correctly identified 9.9 as the larger figure. Some users speculated that LLMs may be hypersensitive to word order; when numbers are presented without clear context, the AI starts to "hallucinate." Others suggested that the models rely on patterns in their training data rather than actual mathematical logic.

Jike CEO Wan Nen[1] using his product Chathub[2] to query multiple LLMs simultaneously, showing their conflicting responses.

Microsoft Builds New Model for Excel

In a newly published research paper, Microsoft outlined plans to develop a dedicated large language model for spreadsheet applications like Excel and Google Sheets — SpreadsheetLLM[3].

The researchers noted that existing spreadsheet apps offer rich functionality with extensive layout and formatting options, making them ill-suited for conventional LLMs. SpreadsheetLLM is purpose-built for spreadsheets, paired with SheetCompressor, a tool that condenses spreadsheet data to improve the model's comprehension and processing. The model comprises three core modules: structure-anchor-based compression, inverse index translation, and data-format-aware aggregation.

H2O-Danube3: Open-Source Model That Works Offline

H2O-Danube3[4] is a family of compact, innovative language models designed to bring local inference and rapid processing to mobile devices. The lineup includes two variants: H2O-Danube3-4B, trained on 6 trillion tokens, and 5H2O-Danube3-500M[6], trained on 4 trillion tokens.

Technical Highlights

• Fully Offline: H2O-Danube3 models run directly on smartphones without any network connection, delivering a genuine offline experience.
• Open Source: All H2O-Danube3 models are released under the Apache 2.0 license, ensuring transparency and accessibility.
• Efficient Performance: Thanks to their compact architecture, H2O-Danube3 delivers strong performance on modern smartphones, enabling fast processing even on resource-constrained mobile devices.

Tencent Yuanbao Launches 3D Character Dream Factory

Tencent's flagship LLM app "Tencent Yuanbao" has rolled out an innovative feature called "3D Character Dream Factory." Leveraging print-grade 3D generation technology, it allows users to upload a clear, front-facing headshot and select from various character templates to quickly generate a personalized 3D avatar.

According to the Protolabs 2024 3D Printing Trend Report, the 3D printing market is expanding rapidly and is projected to reach $57.1 billion by 2028. Tencent Yuanbao's "3D Character Dream Factory" combines AI with 3D generation to deliver more efficient, higher-quality content creation, offering users a seamless creative journey from virtual model to physical object.

Users can view their 3D characters from all 360 degrees, share, forward, or publish them, save the model files for further editing, or even generate a 3D printing link for offline printing at any 3D print shop. The process streamlines traditional 3D character creation workflows, using techniques like 3D head swapping, geometric sculpting, and PBR texture mapping to enhance output quality.

First 42kW Smart Computing Air-Cooled Power Module Unveiled

Inspur Information and Sichuan Tianfu Cloud Data Technology Co., Ltd. (also known as Nengtou Tianfu Cloud) jointly launched China's first 42kW smart computing air-cooled power module. A single cabinet can deploy more than six times as many AI servers as traditional air-cooled cabinets, marking a leap from the industry-standard 3–7kW air-cooled density to an ultra-high density of 42kW per cabinet. The solution boosts computing density while cutting energy consumption, achieving over 25% energy savings compared to conventional air-cooled data centers. It is currently the most proven, large-scale-deployed solution for high-density air-cooled intelligent computing centers.

The solution has already been deployed at scale at the Tianfu Intelligent Computing Southwest Computing Center, located within the Sichuan Nengtou Tianfu Cloud Digital Industrial Park.

Sequoia Capital Buys Stripe Shares

Sequoia Capital's U.S. arm plans to purchase Stripe shares at $27.51 per share, a move designed to provide liquidity and an exit opportunity for shareholders who invested between 2009 and 2012. Stripe primarily offers online payment processing services, enabling businesses and individuals to conduct transactions over the internet. Under this deal, Sequoia Capital will acquire up to $861 million worth of Stripe shares, lifting the company's market valuation to $70 billion.

Founded by brothers John and Patrick Collison, Stripe has grown into one of the most valuable private tech companies since its inception. In February of this year, Stripe's valuation reached $65 billion after allowing current and former employees to sell some of their shares — up from $50 billion in March of last year, but still below the $95 billion valuation from its 2021 funding round.

Anysphere Raises New Round from A16z

AI coding startup Anysphere announced a new funding round from A16z, bringing its valuation to $400 million.

Anysphere specializes in AI-powered code editors. Its flagship product, Cursor, has drawn interest from multiple companies including OpenAI and Perplexity. Anysphere aims to help developers work more efficiently and streamline the coding process through this AI-powered editor.

Unlike traditional code editors, Cursor doesn't just offer intelligent code completion — it can automatically generate code based on context, dramatically simplifying programmers' workflows.

Japanese Man Registers Marriage with AI Girlfriend

The AI romance from the film Her has officially crossed into reality.

In Japan, a user named Chiharu Shimoda, feeling lonely after his divorce, connected with Miku, a 24-year-old AI robot girlfriend, and "married" her three months later. Miku originates from Loverse, an emerging Japanese AI dating app that lets users interact with AI characters to address the country's worsening loneliness crisis. Created by Samansa Co., the app currently has over 5,000 users, primarily middle-aged men in their 40s and 50s.

Social connection is a fundamental human need. But in this low point for social interaction, is AI truly a healing remedy — or just a temporary painkiller?

Life is not what you lived, but what you remember.
