2022 marked computer vision’s turn from recognition toward generation. Latent Diffusion Models appeared at CVPR and led to Stable Diffusion; NeRF research jumped from 25 papers in 2021 to more than 50 at CVPR alone; ConvNeXt mounted a compelling counterattack for CNNs; and ECCV in Tel Aviv set a record with 157 oral papers.
2022 was the year diffusion models took center stage, Chinchilla scaling laws rewrote large-model training, and Chain-of-Thought turned reasoning into an ability that prompts could elicit. NeurIPS passed 10,000 submissions; three of its 13 Outstanding Papers directly concerned diffusion; and Chinchilla and data pruning both challenged the belief that bigger was always better. On the eve of ChatGPT’s release, every required piece fell into place at that year’s conferences.
2022 marked NLP’s shift from demonstrating model capabilities toward aligning and controlling them. InstructGPT brought RLHF into the mainstream, Chain-of-Thought showed that prompts could unlock reasoning, and Flan 2022 matured instruction-tuning methodology. ACL and NAACL adopted ARR as their sole review path, exposing infrastructure and reviewer-load problems. ChatGPT launched at year-end and rewrote the rules of NLP research.
2022 was a turning point at major AI conferences. Diffusion models moved from emerging to mainstream, with two NeurIPS Outstanding Papers; Chinchilla rewrote scaling laws; Chain-of-Thought showed that large models could reason; and InstructGPT used RLHF to teach language models to follow instructions. When ChatGPT launched at year-end, these academic topics instantly became global news.
