The Technical Leap Behind ChatGPT 4.5

A Bigger, Smarter Transformer

ChatGPT 4.5 expands the parameter count to 1.8 trillion, up from 1.2 trillion in GPT‑4. It employs a Sparse‑Mixture‑of‑Experts (MoE) architecture that activates only the most relevant expert sub‑networks per token. This design delivers:
