The GPT-Rosalind-6 model achieved a 37.7% single-attempt success rate on GeneBench Pro v13 tests, outperforming GPT-Rosalind-5.5 which scored 16.7%. These results were obtained using a benchmark-specific configuration, not a production setup. OpenAI plans to monitor GPT-Rosalind-6's real-world use, including safety signals and misuse patterns, to inform future safeguard updates.

LongCat-2.5 is a large multimodal model designed for agentic tasks, featuring native multimodality. It boasts a total of 1.6 trillion parameters. The entire training process for this model was completed using domestically produced chips.

Researchers have found that Large Language Models (LLMs) demonstrate proficiency in natively reading and writing neural network weights. For instance, GPT-6 Astra successfully edited the weights of Qwen3.5-0.8B, resulting in improved mathematical capabilities for the latter. This suggests a novel approach to neural network development and optimization, potentially allowing LLMs to directly manipulate and enhance other models' functionalities.

Momentic (YC W24) offers an AI QA engineer that tests applications end-to-end, catching bugs before they ship. It allows users to verify critical flows and find bugs from a prompt, with reported metrics including 77,813 tests created, 70,607,819 test runs executed, and 117,010 bugs caught. Momentic aims to accelerate software development by integrating verification into the agent loop, enabling teams to ship faster and with greater confidence.

A study on modernizing legacy PHP code with LLMs found that simply asking an LLM to "modernize this" often breaks working code. Researchers evaluated five LLMs on 100 WordPress 4.0 PHP files, aiming to update them to PHP 8.3 while preserving behavior. The LLMs broke 32-51 files, repairing at most 10, compared to Rector which broke 7 and repaired 6. Much of this damage was unnecessary, as only 37 findings required changes for PHP 8.3 compatibility.

SemiAnalysis has introduced GDPx, an agentic capability benchmark designed to evaluate performance across 11 distinct domains. These domains include critical areas such as chip design, cybersecurity, and RSI. The benchmark aims to provide a comprehensive assessment of agentic capabilities. In its initial findings, Opus 5.5 achieved the highest score, reaching 12%, indicating its leading position among the tested agents in these diverse fields.

Aarush and Arnav from The Subvocal Company (YC F26) have developed smart glasses called Subvocal, enabling users to interact with computers silently. These glasses decode mouthed words into text at speech speed, addressing the challenge of using voice dictation tools like Wispr Flow in public or quiet environments. Inspired by MIT's AlterEgo, they built a prototype at Stanford’s TreeHacks. Preorders for the first batch of 500 units are now open with a $200 discount.

HackerBooks, inspired by Karpathy's HackerTube, is a new platform listing approximately 16.5k books mentioned by at least two different Hacker News commenters since 2007. Each book entry links back to the original comments. The data is downloadable, and the site, including its data pipeline, was largely built by Claude Opus 5.5, with the creator primarily providing direction and handling logistics like domain registration. The platform counts mentions, so it's not a perfect recommendation system.

Anthropic, an artificial intelligence company, reported $33.24 billion in revenue for the nine months ended September 30, marking a 1,200% increase from the previous year. The company also reported a net loss of $104 billion during this period, largely attributed to changes in the fair value of convertible notes and derivative liabilities. This follows a $25.1 billion loss over the same period in 2025.

Anthropic's internal AI use, when valued at retail prices, has now surpassed its employee pay. This development highlights a significant shift in the company's operational costs, indicating a substantial investment in or reliance on its own AI technologies. The information comes from Business Insider's AI Insider franchise, led by Alistair Barr, who covers Big Tech, startups, and venture capital, including topics like AI and cloud computing.

OpenAI is reportedly rebranding its data centers as “compute campuses,” a move some suggest is an attempt to soften public perception and compete with rivals like Anthropic. Data centers often face bipartisan opposition due to their noise and resource consumption. Anthropic, for its part, has pledged to cover power grid upgrade costs, invest in community projects, protect water supplies, and avoid NDAs with public officials, applying these commitments to both leased and owned facilities.

OpenAI is experiencing unprecedented growth, making it one of the fastest-growing technology companies ever, yet it's also burning through cash at an extraordinary rate. This has led to concerns on Wall Street, with discussions around its corporate restructuring, the reasons investors continue to fund a company losing billions, and the fatal cost problem behind every ChatGPT answer. The financial ties between Nvidia and OpenAI's survival, and the potential impact of an OpenAI IPO on retirement funds, power bills, and taxes, are also significant points of discussion.

OpenAI VP of Global Creative Partnerships, Charles Porch, an ex-Instagram executive hired from Meta, is actively working to improve AI's public image. He is leveraging his extensive network and experience, including hosting celebrity dinners, to rehabilitate AI's cultural perception across Hollywood and the media. Porch's strategy aims to make AI more palatable to celebrities and the general public, drawing on methods similar to his past Instagram playbook.

Tel Aviv-based 42AI, an Israeli startup, has emerged from stealth with a $62.5M seed funding round. The company is developing a "behavioral world model" designed to predict human actions. This technology aims to anticipate how individuals will behave, even in novel situations, raising questions reminiscent of science fiction scenarios regarding AI's predictive capabilities.

Vera Health, an AI-powered medical search engine, recently secured $28.5M in Series A funding. The round was led by Threshold Ventures. Vera Health states that its platform is currently utilized by over 800,000 clinicians across 190 countries, highlighting its significant global reach in the medical field. This funding will likely support further development and expansion of its AI capabilities.

Tutor Intelligence, a company focused on training robot foundation models and building AI warehouse robots, successfully raised $75M in a Series B funding round. This round was led by a16z, bringing Tutor Intelligence's total funding to $117M. The company's work involves developing frontier robot foundation models, indicating a focus on advanced AI for robotics applications.

Data analytics provider Hex Technologies has successfully raised a $100M Series D funding round, led by Peak XV. This investment values the company at $1.2B. Hex Technologies states it has rebuilt its platform specifically to support AI agents, positioning itself within the evolving enterprise tech landscape.

Elon Musk stated that the cost of operating Grok Bot was "unsustainably high relative to revenue." This acknowledgment came after subscribers expressed complaints about the rapid depletion of usage limits for SpaceX's AI agent. Musk's comments highlight the financial challenges associated with serving the Grok Bot, particularly in light of user feedback regarding its operational constraints.

Bites, a company providing AI tools for personalized training to frontline workers, has successfully raised $40M in a Series A funding round. This round was led by PeakSpan. Bites' platform converts company procedures into concise, branded videos, which are then delivered through popular communication channels such as WhatsApp, SMS, and Slack, facilitating accessible and familiar training methods for its users.

Matt Scherer, co-author of "Brace for Impact: Protecting people and the economy when the AI bubble bursts," argues that the SEC should block Anthropic's IPO. He cites concerns about insufficient demand for generative AI, with studies showing LLMs not accelerating productivity or generating positive ROI for most businesses. A study also indicated a significant drop in Americans using AI at work between 2025 (46%) and 2026 (33%). Scherer points to Anthropic's unaudited financial results and relegated future obligations as reasons for the SEC to intervene.

OpenAI has launched the Grid Protectors Program, a US initiative designed for its upcoming data center campuses. This program aims to reduce electricity demand during periods when the grid is under strain. It is a national effort by OpenAI to support affordable and reliable electricity for families and businesses in the communities where they establish their facilities.
