Ranking AI Models and How I Use Them February 3, 2026
Since ChatGPT's public release in late 2022, I was hooked. Not a single day has passed without me using AI for something. I remember the first school assignment I used it for—a microbiology essay on bacterial classification and antimicrobial resistance mechanisms. The speed and accuracy with which it completed the task blew my mind. I'd never seen anything quite like it.

But those GPT-3.5 days feel like ages ago now. Newer, better models have been released. Even Google managed to turn over a new leaf from its catastrophic Bard days. In my daily tasks, I've found different models useful for different things. Here's my ranking:
Casual browsing & quick facts
Google AI Overview
I was using GPT-4o at first—it's good and its responses felt authentic. I'd almost given up on Google Search entirely; you had to sift through multiple pages to find what you wanted. ChatGPT was concise and direct. But Google has made a comeback with its AI Overview feature. Honestly, I use it more often than ChatGPT now for browsing because it's grounded in real-time search results rather than pre-trained (sometimes outdated) data.
Writing
Claude Sonnet 4.5 (Anthropic)
I still try to do as much writing myself as possible. Writing is thinking, and I don't want to delegate my thinking—the mind decays from disuse. I mostly use AI to correct grammar, improve word flow, and explore facts about ideas I'm developing. Claude is hands down the best here. It understands nuance and tone better than anything else.
Coding
Claude, Gemini 3.0 and Gemini 3.0 Flash
Claude models are the most intelligent when it comes to vibe coding. Claude really understands what you're trying to do when you describe your codebase. But it's not free, and I often hit my usage limits. Then I have to wait hours for them to reset. That's where Google comes in with Gemini 3.0 and Gemini 3.0 Flash—very generous free tier. I use these for the bulk of my coding tasks. Best accessed via Google AI Studio.
The Birthday Paradox February 3, 2026
The first time I saw this, it seemed unbelievable: in a room of just 23 people, there's a 50-50 chance two share a birthday. In a room of 75 people, it's a 99.9% certainty.

Looking back at my life, maybe it's true after all. In my high school class of about 28 people, I shared a birthday (August 9) with someone. Again at university (class of about 250), I share it with someone else.

I've attached a paper that shows the mathematical proof. They did a really good job simplifying the math—most mathematicians pride themselves on obfuscation and writing confusing papers. I've gotten headaches from some. If you like math, dig in.

Do Phones and Bluetooth Devices Cause Cancer? February 3, 2026
There are popular concerns that radiation from electronic devices—mobile phones, Bluetooth headphones—can cause adverse health effects like cancer. In this 2012 report from the independent Advisory Group on Non-ionising Radiation to the Health Protection Agency in the United Kingdom, Chapter 3 (pages 80-116) discusses all possible carcinogenic mechanisms of these devices, cites several studies, and concludes:

"Results of multiple studies remain divergent with no obvious reason as to why some researchers find effects and others do not. There is still lack of independent replication of results, and where replications have been undertaken they do not support the original findings. This continued lack of robust evidence makes the possibility of Radio-frequency (RF) fields affecting cells more unlikely."

In other words: no convincing evidence that your phone is giving you cancer.

We Are Going Back to the Moon! February 3, 2026
I've always been a space enthusiast. There's something humbling and fascinating about the infinite vastness of space. Celestial bodies like supermassive stars, black holes, and moons are cool.

Preparations are underway for the Artemis II mission, which aims to set the stage for an eventual human landing on the lunar surface for the first time since the Apollo missions of the 1960s and '70s. It's Artemis III that will take us back to the Moon—slated for 2028.
