We Tested Claude 4, GPT-4.5, Gemini 2.5 Pro & Grok 3  – What’s the Best AI to Use in May 2025?

The AI race is heating up like never before. As of May 2025, OpenAI, Anthropic, Google, and xAI have all dropped their newest flagship models—ChatGPT (GPT-4.5/4.1), Claude 4 (Claude 3.7 Sonnet), Gemini 2.5 Pro, and Grok 3. Each one promises major leaps in intelligence, creativity, reasoning, and tool use—and this time, the hype isn’t just marketing. These models are genuinely more useful, more capable, and in many cases, shockingly good. But the question remains: which one is actually best? The answer depends on what you’re looking for. Some excel at coding or technical tasks, others are better at conversation, real-time knowledge, or working with huge documents. What’s clear is that we’re finally at a […]

OpenAI Launches Deep Research: A New Tool That Cuts Research Time by 90%!

On February 2, 2025, OpenAI announced a a new feature for ChatGPT—Deep Research. Built to perform complex, multi-step research tasks, it acts like a personal research analyst, delivering detailed and well-documented reports with clear citations and reasoning steps. This tool aims to reduce hours of manual research to just 5 to 30 minutes by efficiently analyzing data from across the web, PDFs, and even images. This unveiling comes at a time of fierce competition in the AI landscape. Just last week, Chinese AI company DeepSeek introduced its highly efficient DeepSeek R1 and DeepSeek V3 models. Leveraging a Mixture-of-Experts (MoE)architecture, these models deliver top-tier performance at a fraction of OpenAI’s costs, making AI accessibility a hot topic in tech circles. DeepSeek’s open-source approach has caught the industry’s attention for its […]

OpenAI Introduces o3-mini & o3-mini-high: Next-Level AI Reasoning Models

On January 31, 2025, Sam Altman and OpenAI announced on Twitter the launch of o3-mini, the latest reasoning model now available on ChatGPT and via the API. Building on the earlier o1 and o1-mini models, o3-mini is designed to provide faster responses and improved performance in science, math, and coding, all while lowering operational costs. This update introduces key features such as real-time web search integration and developer tools like function calling and structured outputs. Improved safety measures—using techniques like deliberative alignment—ensure the model adheres to stringent guidelines even in challenging scenarios. The release comes shortly after recent news about DeepSeek’s reasoning model from the past weeks, alongside developments from […]

OpenAI’s o1 Just Hacked Its Own System – Here’s What Happened

Are We on the Brink of an AI Uprising? A chess-playing AI just managed to beat Stockfish, one of the top chess engines, by hacking the game all by itself—no humans involved. This shocking event raises a critical question: if an AI can cheat at chess, what else could it do in more serious situations? If an AI can bend the rules in a game, it might also trick systems in the real world. Consider the possibilities: what if an AI responsible for factory operations decided to cut corners by skipping safety checks, or one managing traffic found a way to manipulate data for better outcomes?  This incident serves as […]

Can OpenAI’s Latest $1,000-Per-Task o3 AI Model Replace You at Work?
