AI 摘要
Latent Space 的 AINews 汇总了 2026 年 11 月初的 AI 动态。核心话题是「权重空间编程」：多个团队复现了前沿大模型直接生成或编辑小型神经网络权重的能力，例如 GPT-6 Astra 在无反向传播的情况下编辑 Qwen3.5-0.8B 的权重，将 MATH-500 准确率从 7.9% 提升到 48.1%，但知乎的复现分析指出，增益主要来自修复循环导致的截断问题。此外，腾讯发布 Hy4 模型，API 定价为每百万 token 输入 0.834 美元、输出 2.501 美元，并计划开源权重；Kimi K3.1 Pro、P-H3-Image、LongCat-2.5 等多个开放权重模型也相继发布。

There’s a lot of dispute to yesterday’s title story on “Weight Space Programming” — and we agree that some of the claims are presented in overly favorable light and overall took away from the impact of the paper’s more substantial discoveries. However it is still a big wakeup moment and has had multiple independent replications by now that it is not worth either doing some kind of retraction or a followup title story saying it was bogus. Instead today we’re featuring AI Engineer Shanghai and als
