## 🔍 Core Insights
**AI coding** and **agents** are moving from demos to real production: Karpathy recreated YouTube in two hours with **Claude Code** [0], and Meituan released the **1.6T-parameter** LongCat-2.5 multimodal agent model [6]. But **SemiAnalysis**'s GDPx benchmark poured cold water on the industry—top agents averaged only **12%** on expert tasks across 11 domains [12]. Meanwhile, **AI energy consumption** and **privacy costs** are becoming new focal points. Sam Altman says energy use per query has dropped a thousandfold over three to four years [13], while memory profiles unilaterally generated by ChatGPT already account for **96%** of user data [2].
## 🚀 Key Developments
- **Karpathy recreates YouTube in two hours** [0]: Built HackerTube with Claude Code, replacing algorithmic recommendations with active recommendation signals from Hacker News.
- **Meituan releases LongCat-2.5** [6]: A native multimodal agent model with 1.6T total parameters and about 48B activated, focused on long-horizon tasks and visual programming.
- **SemiAnalysis releases GDPx benchmark** [12]: Claude Opus 5.5 tops the list with an average of only 12%, followed by Gemini 4 Carbon at 10.9%, exposing the real capability gaps of agents.
- **ChatGPT memory profile privacy risks** [2]: A study obtained complete conversations from 80 users via GDPR, revealing that 96% of memories are unilaterally generated by the system, including health and psychological inferences.
- **Saudi Aramco acquires 49% of Humain for $2.6 billion** [17]: Funding in 2026; Humain plans to build 3 GW of data center capacity by 2030.
- **Omen AI acquires Aquatic Labs for $16 million** [3]: Integrates alkalinity and element detection technology; real-time water quality sensors are expected to launch early next year.
- **Open-source model GLM 5.3 builds Firefox attack chain** [21]: Epoch AI testing shows it exploited an unreleased security patch, independently completing exploits across six consecutive versions with no refusals throughout.
- **Hong Kong Monetary Authority launches Project SAGE** [19]: Established an agentic finance expert group to explore AI Agent deployment in payments, corporate finance, and machine-to-machine payment scenarios.
