GPT-5 Complete Review: OpenAI’s Latest AI Breakthrough 2025

So I’ve been messing around with GPT-5 for the past couple weeks. Gotta say, I went in pretty cynical - we’ve all been burned by AI hype before, right? “Revolutionary this, breakthrough that.”

But damn. This one’s different.

Got early access through work (perks of being in tech, I guess), and honestly? First hour of testing had me texting my developer friends like “dude, you need to see this.”

🚀 What is Google Opal?

Google Opal is a new experimental tool from Google Labs that lets you build and share powerful AI mini apps that chain together prompts, models, and tools — all using simple natural language and visual editing. Launched in July 2025 as a US-only public beta, Opal represents Google’s ambitious entry into the rapidly growing “vibe-coding” market.

The platform embodies the “vibe coding” trend, a term popularized by AI researcher Andrej Karpathy in early 2025. Vibe coding emphasizes intuitive, AI-assisted development where users guide the process through conversational prompts, focusing on creativity over technical details.

Google has just released Gemini CLI, a powerful new command-line interface that brings Gemini 2.5 Pro directly to your terminal. It’s free, open-source, and surprisingly capable. If you’re a developer or power user, this tool might soon become a core part of your workflow.

Recent findings from security researchers show that browser automation agents and AI-powered bots are exposing businesses to a new class of risks. Some even call them more dangerous than human employees when it comes to security hygiene.
