OpenAI 大幅降价 GPT-5.6，智能成本四个月降 13 倍
原标题：[AINews] GPT 5.6 price cut by 20%-80%: Cost of GPT 5.4 Intelligence dropped 13x in 4 months due to GPT 5.6 recursive self-optimization
AI 摘要
OpenAI 宣布大幅下调 GPT-5.6 系列模型价格，其中 Luna 降价 80%，Terra 降价 20%，并推出延迟降低 2.5 倍的 Sol Fast 模式。降价得益于 GPT-5.6 的递归自我优化，包括自主内核优化、推测解码和 KV 缓存等推理加速技术，以及智能体框架的改进。相比四个月前，GPT-5.4 级别的智能成本下降了约 13 倍，年化降幅约 2000 倍，使 OpenAI 在非微调智能的成本效益上极具竞争力。

[AINews] GPT 5.6 price cut by 20%-80%: Cost of GPT 5.4 Intelligence dropped 13x in 4 months due to GPT 5.6 recursive self-optimization Distillation is all you need! One of our big “hero charts” a year ago (eventually adopted by Demis) made the stunning observation that, holding LMSys Elo constant, GPT4 level intelligence fell by 1000x over 18 months: Back then, it was unclear if these were “noob gains” - going from unoptimized to optimized, going from completions to reasoning, going from dense t
