中国首部AI院线电影《三星堆：未来往事》上映：技术里程碑与市场冷遇并存

2026年10月23日，博纳影业出品的《三星堆：未来往事》作为国内首部获公映许可证、全程依托AI参与制作并在商业院线正式公映的长片登陆全国影院。影片全片采用数字角色，无真人演员，制作成本达千万级，但首周末票房仅约118万元，排片与上座率低迷，凸显AI电影在叙事接受度与工业化落地间的现实落差。

推荐理由：该报道基于钛媒体2026年10月26日发布的深度新闻，完整呈现了影片的技术定位（首部AI院线长片）、制作实况（120万张底图、600:1成废比、逐帧手搓）、产业意义（跑通审查与发行全链路）及市场反馈（低票房、票价争议、观众观望），信息要素齐全、来源明确、时效性强，且未超出材料事实边界。

清华与港中文联合开源AKV：面向LLM智能体的KV缓存工程服务系统

清华大学与香港中文大学研究人员于2026年10月26日开源AKV——一个基于SGLang构建、专为大语言模型（LLM）智能体设计的KV缓存工程服务器。该系统通过让智能体主动丢弃并重定位KV缓存（而非传统文本历史摘要），在4个智能体基准测试中平均降低推理成本27.7%，任务平均得分提升1.7分。代码采用Apache-2.0许可证，当前支持Qwen、GPT-OSS-120B和MiniMax-M2.7等模型。

推荐理由：该成果代表LLM智能体高效推理的新范式：区别于依赖文本截断或摘要的‘上下文工程’，AKV直接操作KV缓存状态，避免重复prefill，显著缓解长程交互中的KV压力；实测显示高并发下P95延迟从229.9秒降至30.6秒，具备明确工程价值与可复现性；信息源自MarkTechPost发布的权威技术报道，发布时间（2026-10-26T07:56:45Z）与当前时间一致，属最新公开进展。

common, grammar: add recursive depth limit, make it a requirement (#31153) * common, grammar: add recursive depth limit, make it a requirement * catch more recursive functions * common : tidy up peg parser changes * grammar : reject candidates in a loop, without a depth limit The depth limit in llama_grammar_reject_candidates_for_stack counted the code points of a vocab token, so any token of 256 chars or more was always rejected under a grammar, such as the 512-space token of GLM-4.7-Flash or the long space tokens of Laguna-S-2.1.

上证指数等四只指数编制规则今起调整；国资委部署深化国企改革；标普新规将波及3750亿美元基金

2026年10月26日起，上证指数、上证A股指数、上证流通指数及科创综指正式实施修订后的编制方案，新增单个样本权重15%上限；国务院国资委于10月23日强调扎实推进新一轮国资国企改革任务落地；同日（10月25日），标普道琼斯宣布调整成长/价值股划分标准，新规将于12月21日生效，影响约3750亿美元被动型基金。

推荐理由：三则政策与市场规则变动均具显著时效性与系统性影响：指数权重红线直接关系A股核心基准稳定性；国资委表态体现中央层面对国企改革攻坚的紧迫部署；标普规则重构价值投资逻辑，波及规模达数千亿美元，属全球资本市场重要变量。所有信息均源自钛媒体2026年10月25日发布的权威综合报道，时间节点、主体、措施及影响金额均明确可验。

llama-quant : fix 4D tensor quantization using ggml_nrows() and name-based expert detection (#30820) * llama-quant : fix quantizing 4D tensors nrows_total was ne[1]*ne[2], so for a 4D tensor only the first ne[2] slices were quantized and the rest of the rows were dropped. Use ggml_nrows(tensor) to count all rows, including ne[3]. Fixes #29916 * llama-quant : detect expert tensors by name and fix imatrix size for 4D tensors The MXFP4_MOE path used ne[2] > 1 to detect MoE expert tensors. This is wrong for non-expert tensors with 3 or more dims, e.g. MLA projections (BailingMoE3) and 4D conv kernels. Use the tensor name instead: all tensors used by GGML_OP_MUL_MAT_ID are named *_exps or *_chexps. This also removes the BailingMoE3 special case. The imatrix holds one vector of ne[0] values per

CUDA: fuse FFN gate/up matmuls and GLU in MMQ with interleaved gate/up rows (#29948) * cuda: fuse FFN gate/up and GLU in MMQ with interleaved gate/up rows For prompt processing, run the gate and up matmuls of a dense FFN as one mul_mat_q launch and apply the GLU in the write-back. - The loaders take the gate weights as a second pointer and fill the weight tile with up and gate rows interleaved in chunks of 8, so each thread holds an up value and the matching gate value (rows r and r + 8 of an MMA tile). - The MMA loop is unchanged: same tile, warp layout, vec_dot and one sum[] per thread. The fused write-back computes the GLU from registers and writes half the rows. - The fused path uses the regular tiling (no stream-k) with the column tiles innermost so that neighbouring blocks share weig
