全球ai由训练走向推理了。软件应用开始冒头。 2024年发布的模型总数同比均有所下降。美国为2024年发布知名模型最多的地区,数量达40个,较2023年的61个同比下降34.43%。分机构看,2024年贡 献知名模型最多的机构分别是OpenAI(7个)、谷歌(7个)和阿里巴巴(4个)。受MoE等新技术推动,2024年模型的参数数量保持快速上升趋势,规模 扩大仍是模型性能提升的重要方式。 随着强化学习时间和推理思考时间的增长,模型性能也将得到显著提升。据前OpenAI应用研究负责人Lilian Weng数据,s1实验中,通过强制延长思维链 推理路径长度,以Token衡量的平均思维时间与下游评估准确率之间展现出明显的正相关关系。据上海交通大学研究表明,通过延长AI的推理时间,仅需 500个样本训练,就能让模型在医疗诊断准确率上提升6%-11%,达到专业医生的诊断水准 。 趋势看,tokens调用激增。 2023-2024年,开发人员采用AI工具率由44%提升至63%。Google每月处理Tokens增长50倍,Microsoft Azure AI Foundry处理Tokens增长5倍。AI模型训练成 本高+的推 ...
