What Is GPT-4.5 and Why Is Everyone Talking About It?

GPT‑4.5 is OpenAI’s most emotionally intelligent AI model yet.

It mimics human conversation with unmatched fluency and nuance.

Designed using unsupervised learning, it’s more natural than logical.

GPT‑4.5 shines in writing, summarizing, and storytelling tasks.

It passed a Turing-style test—users mistook it for a human 73% of the time.

Despite its charm, it struggles with complex reasoning and math.

It’s slower and more expensive than GPT‑4o or GPT‑4.1.

OpenAI is phasing it out from its API by July 2025.

Still, GPT‑4.5 set the bar for emotionally aware AI chat models.
