Mark Zuckerberg has criticized rival AI companies for their 'closed' models, as Meta shifts its focus back to open-source AI development. This move signifies Meta's commitment to fostering a more collaborative and accessible AI ecosystem, contrasting with the proprietary approaches of some competitors. The company's return to open models is highlighted by Zuckerberg as a strategic decision to accelerate innovation and ensure broader participation in the advancement of artificial intelligence.

PatronView's owner, Nick Gray, detailed a year-long battle against web scrapers on his 1.5 million-page website. He reported a staggering 214:1 bot-to-human page load ratio and observed 35,000 Claude crawls per referred user, while Amazon's bot referred none. Gray shared his experiences, including attempts, failures, and current successful strategies in combating these automated accesses.

Meta Superintelligence Labs has introduced Muse Glimmer, a 30-billion parameter model optimized for always-on local agent workflows. The model's weights are compressed to approximately 4-bit precision using quantization techniques, reducing its size to under 20 GB. This allows it to run within a 24 GB or 32 GB memory envelope, accommodating its working memory, perception encoder, and speculative decoding drafter. Muse Glimmer is open-sourced under an Apache 2.0 license, with minimal degradation on agentic tasks.

Claude, prompted by an Anthropic staff member, significantly advanced the Riemann Hypothesis by increasing the provable lower bound for the fraction of zeros of the Riemann zeta function satisfying the hypothesis from 41.6% to 67.2%. After 650 initial failed attempts, Claude, coordinating about 60 subagents, ran 2,400 shell commands and wrote hundreds of Python scripts, performing thousands of numerical checks. The staff member's encouragement helped Claude overcome initial skepticism and achieve this breakthrough.

OpenAI's GPT-5.6-Cyber is designed to empower cybersecurity defenders against AI-driven cyberattacks. This model significantly improves upon previous versions, completing 95.0% of advanced cybersecurity requests, such as exploit-chain development and authentication bypass. This is a substantial increase compared to GPT-5.6 Sol (1.5%) and GPT-5.5-Cyber (57.3%), addressing earlier feedback regarding persistent refusals. The development aims to equip defenders with frontier intelligence before attackers widely deploy offensive AI capabilities.

London-based AI startup Cosine is developing a frontier model with support from the UK government. Despite this backing, questions are being raised about the company's capacity, particularly concerning its talent pool and resources. Cosine, which has approximately 30 employees, has reportedly raised only $15 million, leading some to doubt its ability to deliver on Britain's ambition for a "sovereign" AI model.

Singapore has increased its 2026 GDP growth forecast to 4.5%-5.5% from an earlier 2%-4%. This upward revision is attributed to stronger-than-expected global investment in artificial intelligence and improved external demand. The artificial intelligence boom is positively impacting trade and manufacturing, leading to a more optimistic economic outlook for Singapore.
