OpenAI says: “GPT‑3 was a schoolkid, GPT‑4 a college student, GPT‑5 an expert.”
After testing it, I believe them.
Here’s what’s new — and why it matters:
🚀 Depth + Speed — auto‑routes tasks between “fast” & “thinking” layers
📚 256k‑token memory — read an entire novel or year of Slack in one go
🛡 Fewer hallucinations — esp. in healthcare & safety‑critical answers
💻 Real code fixes — 75%+ success on live GitHub issues
💲 Cheaper to read, pricier to write — new pricing shifts your strategy
🛠One model to rule them all — no “model zoo,” router picks the variant
This isn’t AGI — but it’s the most reliable, context‑aware GPT yet.
