    Ollama 推出多模态模型新引擎,支持 Llama 4、Gemma 3、Qwen 2.5 VL 等视觉模型

    Ollama 发布新的多模态引擎,开始支持 Meta Llama 4、Google Gemma 3、Qwen 2.5 VL、Mistral Small 3.1 等视觉模型,可进行多图理解、文档扫描与字符识别。此前 Ollama 依赖 ggml-org/llama.cpp 提供模型支持,新引擎让每个模型自包含并暴露自己的投影层,同时加入图像缓存、显存估算与 KV cache 优化,例如针对 Gemma 3 的滑动窗口注意力和 Llama 4 Scout 的分块注意力。后续计划支持更长上下文、思考/推理、流式工具调用和 computer use。

    Prime Intellect 开源分布式推理栈,面向消费级 GPU 与公网高延迟

    Prime Intellect 发布分布式推理栈预览,并开源 PRIME-IROH、PRIME-VLLM、PRIME-PIPELINE 三个代码库,目标是让消费级 GPU 通过公网连接运行推理。文章指出流水线并行通信需求最低,适合分布式环境,但同步流水线会因 100ms 级跨洲延迟形成吞吐上限,而异步微批调度在内存带宽受限的解码阶段无法带来训练那样的加速。团队称已可用私有硬件通过公网跑推理,正把组件接入自家栈,用于 SYNTHETIC-2 合成数据运行。

    Redis 合并 Vector Sets,成为 Redis 8 原生数据类型

    Redis 作者 antirez 宣布 Vector Sets 已合并进 Redis,从 Redis 8 起作为原生数据类型提供,目前仍是 beta 功能。它采用类似 Sorted Set 的接口,用 VADD 添加、VREM 删除元素,VSIM 做向量相似查询,并支持 8 bit 与二进制量化,其中 int8 量化占用 FP32 约 25% 内存。作者重写了 HNSW 实现以支持真正的节点删除和带谓词的图扫描,VSIM 请求走多线程,Vector Sets 以图的形式序列化到磁盘,重启后加载每百万元素只需几秒。
