club-rdna16 publishes a practical 16GB Radeon local LLM testing repo, with an RX 6900 XT running llama.cpp on ROCm/HIP and Qwen3.6 35B-A3B reaching a stable 131k context using q8 KV cache.

comanderxv published a llama.cpp fork that caches MoE experts in 12GB VRAM; on an RTX 2060 with Qwen3.6-35B-A3B, throughput rose from 19/22 tk/s to 26 tk/s at about a 62% expert-cache hit rate.

NetEase Youdao open-sourced its Ziyue 4.0 multimodal and text-to-speech models, with the 27B multimodal model reporting 81.4% accuracy on Chinese math reasoning tasks and the speech model supporting 14 languages.

Tencent open-sourced the Hy-MT2 multilingual translation model with support for translation across 33 languages; its 1.8B version uses AngelSlim 1.25-bit quantization, occupies 440 MB of storage, and runs locally on mainstream mobile chipsets.

A Reddit user ran DeepSeek-V4-Flash locally on 4 RTX 2080 Ti GPUs, reporting 284B total parameters, 13B active parameters, a sub-$2,500 build, custom Turing CUDA kernels, W8A8 quantization, 1TB DDR4 ECC RAM, and about 255 prefill tokens/s.

Codegraph uses a pre-indexed knowledge graph for symbol relationships, call graphs, and code structure. In the VS Code test, it reduced tool calls from 52 to 3 and runtime from 1m37s to 17s.

The author tested VoiceFlow 1.6.0 on an RTX 3060 Laptop 6GB, where Qwen3.5 0.8B summarized a 4-minute meeting in 57 seconds with 16K context, while Granite 4 350M returned summaries in 0.6-2.8 seconds but fabricated Binance and Star Trek content.

NVIDIA researchers open-sourced LongLive 2.0, an end-to-end long-video generation infrastructure covering training and inference with 4-bit quantization, FP4 quantization, parallel acceleration, KV-cache optimization, and 45.7 FPS generation on a 5B model.

Forge adds five guardrail layers to self-hosted LLM tool calling, raising Ministral 8B to 99.3% across 18 multi-step agentic scenarios, with the accepted ACM CAIS ’26 paper covering 97 model/backend configurations and 50 runs per scenario.

ByteDance released Lance, an open-source unified multimodal model with 3B active parameters that supports image and video understanding, generation, and editing, and the post says it was trained from scratch with a staged multi-task recipe under a 128-A100-GPU budget.

Horizon Robotics Lab open-sourced HoloMotion-1, a 400M-parameter full-body humanoid control model that uses MoE sparse activation and KV-cache inference to reach about 300 FPS on-device, with code and a technical report released.

InsForge released an Apache 2.0 backend platform that lets coding agents deploy, operate, and debug backend systems through one CLI install command and Skills.

openJiuwen released and open-sourced JiuwenSwarm with four components: Agent Swarm, Swarm Skills, Skills Hub, and self-evolution, and the framework supports HOTS and HITS modes for human participation in multi-agent workflows.

SmallCode passes 87 of 100 benchmark tasks with Gemma 4 activating 4B parameters per token. The author attributes the result to compound tools, compile and lint feedback, task decomposition after two repeated failures, and optional escalation to Claude or OpenAI for one task.

api-relay-audit audits AI API relay risks with verifiable three-state decisions and transparent logs, covering AC-1 tool-call rewriting, AC-2 error-response leakage, and context truncation, while the author has published the methodology, comparison results, quick-reference table, and the open-source tool.

MinishLab open-sourced Semble, a code-search tool for agents that combines Model2Vec embeddings, BM25, RRF fusion, and reranking; on a 63-repo benchmark, it used 98% fewer tokens than grep+read, reached 0.854 NDCG@10, and ran CPU queries in about 1.5 ms.

Open AI model teams released Gemma 4, DeepSeek V4, Kimi K2.6, MiMo 2.5, GLM-5.1, and other versions this month, and the post says they were tested under CAISI’s V4 evaluation framework, but the RSS snippet does not disclose scores.

AntLingAGI open-sourced Ring-2.6-1T and listed it on OpenRouter with a 75% discount through the end of May; the trillion-scale reasoning model targets agent workflows, including planning, tool use, context maintenance, and complex task execution, using Async RL and IcePop training methods.

SANA-WM’s title says the project is a 2.6B open-source world model for 1-minute 720p video; the RSS body only lists the project URL, Hacker News comments URL, 9 points, and 8 comments, and the post does not disclose training data, license terms, inference cost, evaluation setup, or benchmark results.
