— 开源大模型正从“可用”奔向“可跑在家”,今天连 2.8T 参数的 Kimi K3 都能在 8GB 内存上推理了。

今日 TL;DR

开源大模型迎来密集发布:Thinking Machines Lab 推出 276B 参数的 Inkling-Small,AMD 发布 16B 的 Instella-MoE,NVIDIA 开源了 RL 框架 Molt。社区极客们则在极限压榨硬件,成功在 8GB 内存的 CPU 上运行 Kimi K3,并为 DeepSeek-V4-Flash 添加了 MTP 支持。此外,Go 1.27 交互式教程上线,Rust 2026 全手会回顾发布。

93% of that 1.56 TB checkpoint is routed experts, and only 16 of 896 fire per token, so the experts never become resident at all.

Thinking Machines Lab 发布 Inkling-Small:276B 总参、12B 激活的开放权重多模态 MoE 模型

Thinking Machines Lab 发布了 Inkling-Small,一个总参数 276B、激活参数 12B 的开放权重 MoE 模型,参数量约为原版 Inkling 的四分之一。该模型在 NVIDIA GB300 NVL72 系统上训练,原生支持文本、图像和音频推理,上下文窗口达 1M tokens,权重以 Apache 2.0 协议发布。为什么重要:其 NVFP4 量化版本仅需 180GB 显存即可在单张 B300 GPU 上运行,大幅降低了前沿多模态模型的部署门槛,对本地推理和中小团队意义重大。

社区极客成功在 8GB 内存 CPU 上运行 2.8T 参数 Kimi K3,并推出专用推理引擎 Mference

一位开发者用 C99 编写了专用推理引擎,利用 MoE 模型每 token 仅激活少数专家的特性,将 1.56TB 的 Kimi K3 模型部署在仅 8GB 内存的单 CPU 上,专家参数按需从 NVMe 硬盘流式加载。同时,另一个开源项目 Mference 也实现了在 5.3GB 内存上运行 DeepSeek-V4-Flash 284B 模型。为什么重要:这证明了超大 MoE 模型在消费级硬件上推理的可行性,通过极致的专家卸载和流式加载策略,彻底打破了“大模型必须大显存”的固有认知。

社区普遍惊叹于这种极限优化,但也有人指出这更像技术演示,实际推理速度可能极慢,实用价值有限。

NVIDIA 发布 Molt:一个 PyTorch 原生的 Agent 强化学习框架

NVIDIA NeMo 团队开源了 Molt,一个专为 Agent 强化学习研究设计的 PyTorch 原生框架。其核心 RL 代码仅约 8.6K 行,通过组合 Ray、vLLM 和 NeMo AutoModel 构建异步训练循环,旨在让研究者能轻松修改算法而不必深入分布式后端细节。为什么重要:当前 Agent RL 研究常因框架复杂度过高而迭代缓慢,Molt 的极简设计有望显著降低实验成本,加速 Agent 智能体的算法创新。

Go 1.27 交互式教程上线,泛型扩展成社区焦点

VictoriaMetrics 团队发布了 Go 1.27 的交互式学习教程,延续了社区传统,通过可运行示例展示新版本的语言特性变化。该教程基于官方发布说明和 Go 源码编写。为什么重要:Go 1.27 引入了泛型的进一步扩展,这对习惯于简洁语法的 Go 开发者社区是一个重大变化,交互式教程能帮助开发者快速上手并理解新特性的实际行为。

社区普遍关注 Go 1.27 的泛型扩展,认为其语法难读且增加认知负担,但也有人视其为期待已久的关键功能。

Ran DS V4-Flash-0731 Locally on 3xMI50 32GB @ ~15 t/s TG

Hey y'all. I'll be concise. TL;DR: DS V4-Flash-0731 @ UD-IQ2_M running fully in VRAM on 3xMI50s (90.9 GB model, 96 GB VRAM). Actual speed on llama-server is: - Text Generation: ~15-16 tokens/second stable. Never dipped below 14 tokens/second, even when the model was spitting out a 30K token long reply. - Prompt Processing: ~105-110 tokens/second or so. Dipped down on prompt processing of smaller token-length prompts, which is pretty typical of course. llama-server CLI logs, for those interested:

Ten advances in mathematics and theoretical computer science

Now it's OpenAI's turn to flex. They set "an internal version of Astra, our next major model" on finding solutions to ten mathematical problems that "have seen no progress

Karakeep 0.33 release - Semantic Search and Offline Reading!

Hi r/selfhosted , it's been a while! I thought I might share this release here as it contained a bunch of things that people have been asking about for, for a while! Before we get to 0.33, I want to remind people what Karakeep is. Karakeep ( ), is a selfhosted bookmark manager that's meant to be the place where you throw things in that you might need in the future, and it aims to help you with retrieving those things easily in the future. It has a blazingly fast full text search and opt-in LLM b

Open letters about AI development

Open letters about AI development I wrote this summary of the past few weeks of open letters as a section of my sponsors-only newsletter but I've decided to share it here as well. Open Weights and American AI Leadership was shepherded by Microsoft, dated July 24th, and signed by 235 AI-adjacent companies including NVIDIA (see Jensen's first ever tweet ), Amazon, Y Combinator, The Linux Foundation, and (a later signer) OpenAI. It's clearly an argument designed to counter any instincts by the curr

End-to-End Forecasting with TimesFM 2.5: Backtesting, Covariates, Anomaly Detection, and Scalable Colab Deployment

In this tutorial, we build an advanced end-to-end time-series forecasting workflow with TimesFM 2.5. We begin by configuring the runtime, installing the required dependencies, detecting available hardware, and generating a realistic multi-store retail dataset with trend, seasonality, pricing, promotions, holidays, temperature effects, and random variation. We then load and compile the TimesFM 2.5 model, examine […] The post End-to-End Forecasting with TimesFM 2.5: Backtesting, Covariates, Anomal

StatePlay: State-Aware Game World Models for Mechanics-Consistent Generation

Recent game world models can generate visually realistic and interactive environments conditioned on player actions. However, games are not defined by pixels alone; they are governed by explicit mechanics, namely state-dependent rules that control health reduction, skill activation, and game termination. These mechanics depend on precise internal states, such as health points, skill meters, and timers, which are tightly coupled with visual observations and determine how gameplay evolves. Without

Conclusion: r/LocalLLaMA still has brilliant open-weight research, but finding it requires wading through endless benchmark drama, non-local Discussion Points and repetitive hardware flexes.

I let Gemma4-31b run on my laptop for like almost a day using a heavily altered pi to do a deep dive on our beloved Llama tangentially related Subreddit, and this was the conclusion. Feels pretty accurate. Kind funny to let a small LLM loose and see what happens. Next target I'm trying to let it steal some benchmark answers from Huggingface, wish me luck.

Are you ready for Le Chaton FAT or still wasting money on GPUs?

According to rumors (spread by myself) Le Chaton FAT will be 26T-a3b and I AM READY for it. Let's be real, I can't afford that many 5060Ti, so I got 12x Gen 4 3.2 TB (two per card). This gives me about 60GBs bandwidth on 30TB. Added 256gb ddr4 just for kv cache, but I can also write KV-cache to the disks, these are high endurance drives. Are you ready for the next era of local inference? Jokes aside, this is what I use for my HF_HOME - model and dataset storage. I'm also setting up a few contain
