How ChatGPT Cuts Infrastructure Costs: The Engineering Behind ChatGPT's Battle Against Rising Compute Costs

OpenAI's ChatGPT triumphs over exploding compute costs through Mixture-of-Experts (MoE) architecture that activates only a fraction of its trillion-plus parameters per token, aggressive quantization, advanced KV cache management with paging and prefix caching, continuous batching for high GPU utilization, and speculative decoding. These optimizations, plus recent 2026 software wins cutting inference costs by over 50%, enable affordable, high-quality real-time responses at massive scale

How Sora Generates Video: The AI Technology Behind OpenAI's Text-to-Video Model

OpenAI's Sora generates videos using a diffusion transformer (DiT) that processes spacetime patches of compressed latents, enabling coherent outputs with strong 3D consistency and object permanence from text prompts. At its core, the model compresses raw video into a lower-dimensional space via an autoencoder before iteratively denoising noise patches conditioned on detailed text embeddings to simulate realistic motion and world dynamics
