AI INSIGHTS

Another ThursdAI. OpenAI & Anthropic both released new agentic coding models minutes apart, and one of them claims it literally helped create itself.

🤖 OpenAI drops GPT‑5.3 Codex (and yes, it helped build itself). The model was used to debug and evaluate itself during training. Codex 5.3 is what OpenAI calls a step toward agentic interfaces. It handled:

  • 25% faster execution. Upgraded reasoning + pro knowledge

  • Powers the new Codex macOS app (launched earlier this week)

  • Handles complex app/game development across multiple days

  • Transforms from just a “code writer” to a full agent that can do almost anything on a computer

🆚 Anthropic moved first with “Vibe-coding” Claude Opus 4.6. Originally, both companies planned to launch at exactly 10AM PT. But Anthropic pushed by 15 minutes. Opus 4.6 improves across the board:

  • Longer task chains without dropping the ball

  • Can pull info from doc sets, do research, even run full financial analyses

  • Ranks #1 on the Finance Agent benchmark (yep, beating OpenAI)

  • Sustains focus on longer, more complex tasks without breaking

Codex 5.3 is building itself. Claude 4.6 is replacing work apps. And both are aiming to make you obsolete… or superhuman.

AI HIGHLIGHTS

📺 Super Bowl LX this year is all AI. Anthropic’s ad subtly trolled OpenAI over ads in ChatGPT. Then, Altman fired back on X, calling the whole thing “clearly dishonest.”

🏈 Google’s Super Bowl ad for Gemini also hit hard. It’s warm, and built to sell “helpful AI” to the masses. Bikes, Madden Bowl, and even influencer blitz incoming.

📉 Anthropic just dropped 11 Claude Cowork plugins. Wall Street freaked out, software stocks tanked. But Nvidia’s CEO Jensen Huang called the selloff “illogical.”

🛠️ GPT-5.3 Codex is impressing devs with new tools and smoother builds. Here’re some outstanding things that builders in community are saying & shipping with it.

🧠 Upload these "AI Humanizer" rules to your chatbot’s preferences to make it sound & act way more human (less fluff, no em dashes, sharper answers, etc).

🚀 OpenAI just launched Frontier, a new enterprise AI platform to turns AI agents into real coworkers. It connects tools, runs code, even uses files. See it in action here.

AI BREAKTHROUGH

q4-earnings-call-googles-gemini-is-scaling-like-crazy

If you thought Gemini was just Google's answer to ChatGPT, think again. Google’s Q4 earnings just revealed it’s now a full-blown ecosystem at scale. Key points:

  • Gemini app now has over 750M monthly active users. That’s more than TikTok in some regions, and it’s only been live for a short time

  • Enterprise is booming. In just 4 months, 8 million paid seats of Gemini Enterprise sold, used by 120,000+ businesses

    • 95% of the top 20 SaaS companies

    • 80% of the top 100 SaaS companies

    • 5 billion+ customer interactions handled in Q4

    • 65% YoY growth, not test pilots, but real deployments

  • Gemini 3 Pro is the fastest-adopted model in Google’s history. It processes 3× the daily tokens of Gemini 2.5 Pro

  • Daily AI Mode queries per user: 2× since launch. 1 in 6 AI Mode searches use voice or image

  • Google Antigravity, their new AI workbench powered by Gemini, now has 1.5M+ weekly active users, in just 2 months

  • Google’s planned 2026 capital expenditure: $175–185B

Our take: OpenAI and Anthropic may lead in raw model elegance, but Google just pulled ahead in distribution, infra, and product-layer dominance.
