AI's ten big moments of 2025

Pretrained ·

2025/12/17

It's been a long year in the world of AI. Benchmarks are now almost totally saturated; the financial bubble keeps growing; spending more on inference compute; increasing competition from open source models; agents finally reach the mainstream; the frankly horrible job market for people out of school; multi-model models are back and increasing converging on transformer architectures. We cover them all in our anything goes holiday recap show. Plus - all the things that didn't happen this
