OpenAI’s launch of GPT-5 changed how ChatGPT works. Instead of choosing between models like GPT-4o, GPT-4.5 or o3, you now get one unified GPT-5 system. It responds quickly to simple prompts, but can automatically switch into a slower, more thoughtful mode called GPT-5 Thinking for complex questions. If you’re on a paid plan, you can also turn this mode on manually. And on Pro (and Team) plans, you also get GPT-5 Pro, which uses more compute for the hardest problems. Behind the scenes, ChatGPT is now smarter about how it handles your requests. Most of the time, it gives fast replies using a lightweight model. But when the task is harder—like writing code or […]

Over the past few years, large language models like ChatGPT have become increasingly capable at answering a wide range of questions—from writing code and analyzing data to offering life advice. But even as their capabilities have grown, one thing remains inconsistent: the quality of responses. Users have often reported that answers from ChatGPT can vary significantly in depth, specificity, and usefulness, even when the same model and settings are used. A recent exploration into this inconsistency has revealed a fascinating insight: by adjusting the structure of the prompt, users can reliably activate a more thoughtful and analytical mode of reasoning within the model. The key lies in guiding the model […]

When OpenAI released GPT-4o in 2024, it was widely praised for its creativity, speed, and emotional warmth. For many, it felt like a breakthrough in AI interaction—lively, expressive, and deeply human-like. Then, almost overnight, GPT-4o vanished from the ChatGPT interface, replaced by GPT-5, which—despite major upgrades—has left a significant part of the user base feeling cold, alienated, and frustrated. This article covers why this shift has upset so many users, what GPT-5 does differently, and most importantly, how to keep using GPT-4o today—even if OpenAI no longer features it in ChatGPT. Why People Are Upset About GPT-5 Users feel misledOpenAI had previously implied GPT-4o would stick around. But it disappeared […]

On August 5, 2025, Google DeepMind introduced Genie 3, a major leap in AI-generated interactive environments. The release came on a day packed with significant AI announcements, including Anthropic’s Claude Opus 4.1 and OpenAI’s open-weight GPT-OSS model. While those releases focused on multimodal performance and open-access NLP, Genie 3 targets a different space: real-time virtual world generation. Designed to turn simple text prompts into explorable, dynamic 3D environments, Genie 3 is part of DeepMind’s growing focus on world models — systems that simulate environments for both human users and AI agents to interact with. Unlike previous iterations, Genie 3 supports multiple minutes of consistent simulation, real-time rendering, and the ability to inject events into the environment […]

As generative AI tools like Microsoft Copilot, ChatGPT or Gemini become more common, their real-world impact on jobs is starting to take shape. In a major 2025 study, Microsoft Research analyzed 200,000 anonymized U.S.-based conversations with Bing Copilot to see what kinds of work tasks people are using AI for—and how well the AI handles them. By matching these tasks to official job categories from the O*NET database, the study maps out which occupations are most exposed to AI capabilities. Instead of speculating how many jobs AI might replace, the researchers introduced an “AI applicability score” for each job, based on task frequency, success rate, and how much of the […]

In 2024, experts warned that the internet is rapidly reaching a tipping point: up to 50% of the images we see online could now be fake. AI tools like Midjourney, DALL·E 3, and Stable Diffusion are generating high-quality photos that look nearly identical to real ones — and they’re spreading across platforms like Twitter, Instagram, and TikTok at scale. Hany Farid, a professor at UC Berkeley and one of the world’s leading digital forensics experts, has spent the last 30 years building tools to detect manipulated media. In his TED Talk, he walks through how his team verifies whether an image is authentic or AI-generated. His work has been used by […]

Moonshot AI, the Alibaba-backed Chinese startup, has released Kimi K2, an open-source language model with 1 trillion total parameters and 32 billion activated parameters. This release signals China’s most significant attempt yet to close the gap between open-source and proprietary models like OpenAI’s GPT-4 and Anthropic’s Claude Opus. The model is available in two variants: Kimi-K2-Base for researchers and Kimi-K2-Instruct for general-purpose and agentic tasks. Built on a Mixture-of-Experts (MoE) architecture, Kimi K2 supports 128K context length and is designed for complex multi-step reasoning and tool usage. Moonshot has priced access to the model competitively. The input token cost is $0.15 per million, and the output token cost is $2.50 per million, making it significantly cheaper than GPT-4.1 or Claude Opus. According to CNBC, analyst […]

On July 17, OpenAI has unveiled ChatGPT Agent—a general-purpose AI assistant that not only talks but acts. More than just a chatbot, this new system can autonomously browse websites, use APIs, manipulate spreadsheets, run code in a terminal, generate editable documents—and crucially, do all of this using its own virtual computer. While Silicon Valley has been buzzing for over a year about so-called AI agents—intelligent software that can perform multi-step tasks on your behalf—OpenAI’s rollout marks one of the first times that such capabilities are available to mainstream users. Starting this week, subscribers to ChatGPT Pro, Plus, and Team plans can activate Agent Mode to let the model plan their week, generate pitch decks, […]

Most of us need a decent headshot at some point — for LinkedIn, a website, a speaking event, or just looking more put-together online. But getting one isn’t always easy. Professional photographers can be expensive, booking a shoot takes time, and not everyone feels comfortable posing in front of a camera. That’s why a lot of people are now using AI tools to create headshots from a regular selfie. And honestly? It works better than you might expect. With the right prompt, you can turn an everyday photo into something that looks clean, professional, and polished — without paying hundreds or leaving your home. Whether you want a serious corporate […]

Choosing the right AI assistant in 2025 goes beyond brand hype — it comes down to what the model can actually do. Whether you’re coding, writing, solving complex problems, or just chatting, four AI models dominate the conversation: Grok 4, ChatGPT-4o, Claude Opus 4, and Gemini 2.5 Pro. Each excels in different areas — one leads in deep reasoning, another in natural conversation, and others in creativity or multimodal capabilities. In the past year, AI development turned into an actual race. Each company released their answer to GPT-4o, which had over a year’s head start. Anthropic launched Claude Opus 4 in May 2025, Google DeepMind followed with Gemini 2.5 Pro in June, and xAI dropped Grok 4 in […]
