AI Chips: China vs US

interesting article, some good points, some exaggerations... 

 No more Moore? So, what then for microchips?  And for China? — Kaskazi Consulting: A View from the Indian Ocean

AI summary:

The article argues that as Moore's Law falters, the US strategy of relying on expensive, monolithic chips is becoming obsolete compared to China's system-focused approach. 

Instead of chasing smaller transistors, China is leveraging mature nodes, advanced interconnects, and open software to build cost-effective "Sherman swarm" computing clusters.

This strategy prioritizes "usable compute" and system-level optimization, allowing China to bypass sanctions and achieve high real-world performance at a fraction of the cost.

Ultimately, the author suggests that China's integrated ecosystem and renewable energy advantages will enable it to outmaneuver the US's reliance on raw hardware power.

Harward: Generative AI in Teaching & Learning

a set of brief summary videos, may be interesting to see their perspective...

SpaceX + xAI -> orbital data centers

 Elon Musk is getting serious about orbital data centers | TechCrunch

Musk, who is also the CEO of SpaceX, wrote in a memo posted to the rocket company’s website that the merger is largely about creating space-based data centers — an idea he has become fixated on over the last few months.

The tie-up values the combined company at $1.25 trillion, according to Bloomberg News, which was first to report the completed deal. SpaceX has been reportedly preparing an IPO for as early as June of this year. It’s unclear whether the merger will affect that timeline.

AI: GPT-5.3-Codex from OpenAI

 Introducing GPT-5.3-Codex | OpenAI

"GPT‑5.3-Codex, the most capable agentic coding model to date. The model advances both the frontier coding performance of GPT‑5.2-Codex and the reasoning and professional knowledge capabilities of GPT‑5.2, together in one model, which is also 25% faster. This enables it to take on long-running tasks that involve research, tool use, and complex execution. Much like a colleague, you can steer and interact with GPT‑5.3-Codex while it’s working, without losing context.

GPT‑5.3‑Codex is our first model that was instrumental in creating itself. The Codex team used early versions to debug its own training, manage its own deployment, and diagnose test results and evaluations"

AI: Anthropic Opus 4.6 model

Claude Opus 4.6 \ Anthropic

Anthropic just dropped Opus 4.6... - YouTube

Anthropic released Claude Opus 4.6, upgrading its top model with stronger coding, reasoning, and long-running agent skills. It introduces a 1M-token context window in beta, enabling work across very large codebases and documents. The model leads key benchmarks for agentic coding and knowledge work. Anthropic says its safety performance matches or exceeds other models.

AI tools: Gemini CLI vs Antigravity

Google made it confusing... most likely since Antigravity was not planned, but emerged from acquiring Windsurf team... The benefit of both is easy and free access to Gemini AI, while Antigravity also includes (limited free) support for Anthropic models. 

Gemini CLI and Antigravity are both Google-powered AI development tools,
but they serve different purposes:
  • Gemini CLI is a terminal-based assistant for quick tasks and command-driven workflows, while
  • Anti-Gravity is a full, agentic IDE environment designed for comprehensive, multi-file project management and autonomous coding. 
Anti-Gravity excels in complex, multi-part projects, acting like a team member that can navigate codebases, while Gemini CLI works best for focused, developer-supervised tasks.

Gemini CLI is an open-source AI agent that brings the power of Gemini directly into your terminal. It is designed to be a terminal-first, extensible, and powerful tool for developers, engineers, SREs, and beyond.

Gemini CLI integrates with your local environment. It can read and edit files, execute shell commands, and search the web, all while maintaining your project context.
