Top Stories
Bringing the power of Personal Intelligence to more people
Google AI
We’re expanding Personal Intelligence across AI Mode in Search, the Gemini app and Gemini in Chrome.
Introducing GPT-5.4 mini and nano
OpenAI
GPT-5.4 mini and nano are smaller, faster versions of GPT-5.4 optimized for coding, tool use, multimodal reasoning, and high-volume API and sub-agent workloads.
Justice Department Says Anthropic Can’t Be Trusted With Warfighting Systems
Wired AI
In response to Anthropic’s lawsuit, the government said it lawfully penalized the company for trying to limit how its Claude AI models could be used by the military.
Why Garry Tan’s Claude Code setup has gotten so much love, and hate
TechCrunch AI
Thousands of people are trying Garry Tan’s Claude Code setup, which was shared on GitHub. And everyone has an opinion: even Claude, ChatGPT, and Gemini.
Nvidia’s DLSS 5 is like motion smoothing for video games, but worse
The Verge AI
Yesterday Nvidia revealed its latest upscaling tech, called DLSS 5, which it described as “the company’s most significant breakthrough in computer graphics since the debut of real-time ray tracing in 2018.” Sounds good, until you actually see it. According to Nvidia, the tech “infuses pixels with ph

Deep Dive: Today’s AI Landscape
Synthesized from multiple research sources
Key AI announcements from early March 2026 include major model releases from OpenAI, Google DeepMind, Microsoft, and Nvidia, focusing on advanced reasoning, agentic systems, and efficiency improvements.[1][2][6]
Major Model Launches and Breakthroughs
- OpenAI’s GPT-5.4 “Thinking” Model (March 5, 2026): Released as a reasoning-optimized frontier model with enhanced step-by-step reasoning, coding, cost efficiency, and reduced hallucinations. It builds on GPT-5.3 Instant (early March) for sharper conversations and fewer refusals, positioning OpenAI in the agentic AI era.[1][6]
- Google DeepMind’s Gemini 3.1 Flash-Lite and Deep Think (March 3–4, 2026): Gemini 3.1 Flash-Lite targets high-speed, cost-efficient developer workloads. Deep Think autonomously solved four open math pr

WebSearch isn’t permitted in this session. Here’s what I can do instead:
- Use the Research skill — spawns parallel researcher agents (Perplexity, Gemini, etc.) that have web access
- Use a subagent — launch a
general-purposeagent which has WebSearch access
