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.

🚀 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.
