Open source

AIPrime Intellect says it rewrote its Prime Agent coding tool in Rust, using a swarm of more than 2,000 agents over two weeks. The company reports cold start to typing about 13 times faster than the TypeScript version, and memory use over 80% lower after startup. Prime Agent remains open source and adds native Windows support in beta and Homebrew installation.

Why it matters: The post shows how a multi-agent swarm rewrote a coding agent with parity checks, giving a concrete case of agent-driven software engineering with measured results.

AIA GitHub post announces that kernel kits for DeepSeek's TP=2 and TP=4 recipes are now live. The post links to a repository named deepseek-v4.1-tensorfold-tp2-2xgb10 and gives no further details on performance or features.

AIbig-arrow-on-the-screen (bigarrow) is a MIT-licensed macOS command-line tool and skill for Claude Code and Codex that draws arrows, boxes and text over any window. Clicks pass through, keyboard focus stays put, and each arrow removes itself after a set duration or when its agent process ends. The tool only points; it never clicks, types or captures the screen, and it requires no macOS permission to draw.

AIPrime Intellect says Prime Agent is now open source and that its Rust rewrite is available today. The full blog post covers verification loops, multi-agent orchestration, and performance experiments.

AIPrime Intellect says users can update their Prime Agent by running the command prime-agent update. The post links to the project's GitHub repository, PrimeIntellect-ai/prime-agent.

AIDex Horthy (@dexhorthy) posted only the words "he cook" on X, with no further detail. The post is a short reaction and does not describe a product, release, or result on its own. Background from the quoted post by @0xblacklight describes a serverless background agent that created a GitHub pull request from an issue.

AICline is offering Solar Mini 4 free, a new 35B mixture-of-experts model from Korean lab Upstage with 3B active parameters. It has a 524K context window and runs at 208 tokens per second. Cline says it scores 24 on the AAII, the highest of any model at 3B active and within one point of Nemotron 3 Ultra, which uses 55B active.

AIBoardroom is a free, open-source tool that lets users hold real-time meetings with their AI agents instead of relaying messages between them. The creator says it launches today on Product Hunt.

AIBusabase releases an MIT-licensed open-source database and workspace that lets AI agents write results to a shared, structured space instead of isolated chat histories. The tool turns agent outputs into reusable data, documents, and skills that a whole team can access.

AISyren Video, a new agentic video tool, learns preferred graphics, motion, and editing rhythm from a user's library and generates new videos from a prompt. Users refine the results through chat, and the tool is free to try in a browser or through Claude MCP, per the company's announcement. The post's author says the education sector is exploring it.

AIOpenBMB reports that its MiniCPM5-2B model runs at 37 tokens per second on an iPhone Air. The post presents this as evidence that small open multimodal models can run on mobile devices without a cloud GPU, with NobodyWho noting the model is available in its Chat app.

AIUnderdog has released Saluki 27B under Apache 2.0, a 2-bit GGUF of Qwen3.8-27B that fits in 7.89 GB, versus 54 GB for the full BF16 model. On Underdog Bench, Saluki scores 88 against 84 for the full model, and it raises parallel tool-call accuracy to 42 from 35. It runs on stock llama.cpp, but math and reasoning drop sharply, with AIME 2025 at 79.2 versus 96.7.

AIKingKong Technology has open-sourced the software stack for Jumper, a six-legged crab-style robot it designed, including its MuJoCo model, simulation scenes, reinforcement learning training and deployment tooling. Jumper has 22 degrees of freedom, measures about 400 by 400 by 200 mm, weighs about 1.8 kg and lists a maximum jump height of 400 mm or more. The mechanical CAD files, bill of materials, PCB designs and electrical schematics are not public, and RKNN inference on the real board has not yet been validated.

AIThe vLLM Semantic Router team has released Decision 2.0, which answers multiple questions about one input in a single forward pass and outputs per-option probabilities. The post presents this as useful for routing and classification. A quoted post from Xunzhuo Liu says Decision 2.0 includes six open decision models ranging from 0.6B to 27B parameters, each topping same-size open models on the Jev Decision Index 0.3.

AIopenJiuwen, an open-source AI Agent platform built by Huawei teams with universities and enterprises, released and open-sourced an enterprise-grade AgentOS. It integrates multi-agent collaboration, self-evolution, compute affinity, multi-tenant isolation and security sandboxing, and a plugin architecture with the Agentic Hub ecosystem.

AIOpenClaw says it has added many new features and quality-of-life improvements over the past few months. A video covers new models, multiplayer, interactive dashboards, memory and skills, meetings and voice, and easier Mac setup. It also previews plans for the coming months.

AISimon Willison has released ttok 0.4, a command-line tool for counting tokens built on OpenAI's open source tiktoken library. The update adds a --list-models command, fixes a Click warning, and updates CI, and the tool can run through uvx, for example with cat file.txt | uvx ttok.

AIShanghai AI Lab has open-sourced Intern-Decision, a family of 0.8B, 2B and 4B parameter models that return structured decisions with probabilities instead of free text. The developers self-report that the 4B model averages 90.02% accuracy across seven test suites, ahead of a commercial reference model at 88.74%, with about 44 milliseconds of local latency on a single RTX 4090. Weights are on Hugging Face, and MetaX says the models run on its hardware from launch.

AIThariq, who works at Anthropic, accidentally made public the GitHub repo for ai-newtab, a Chrome extension he uses daily. It replaces the new tab page with an AI-generated homepage built each day from sites he reads.

AIMozilla.ai's cq project proposes a shared knowledge layer where AI agents capture lessons from non-obvious fixes as structured knowledge units that other agents can later query. The default setup is local-first, using a local SQLite database so nothing leaves the machine, with an option to connect to a remote team server that adds review.

AILauren Tan invites users of Grok Bot on Omarchy and developers building plugins for it to share feedback and feature requests. The post points to the Omarchy plugin catalog and asks what integrations could be supported. Background from DHH says SpaceXAI joined the Omacom Foundation as a Founding Corporate Patron, contributing $1,500,000 in Grok tokens for Omarchy's maintenance and development.

AIUnsloth now supports OS-level sandboxing on Linux via bwrap, on Mac via seatbelt, and on Windows via Microsoft's MXC. Per-tool-call latency is under 100ms across all three, and its software-style sandboxing with regex AST checks adds about 3ms. The Windows integration was built in collaboration with Microsoft.

AIOpenClaw released its v2026.9.9 patch, adding support for GPT-6.1 Sol in Codex and Claude Haiku 5.5. The update also improves recovery from failed updates, fixes missing iMessage replies, and resolves scheduled-job issues. The release credits 90 contributors.

AIOpenCode is offering free access to its Step 5 Preview for one week. The announcement highlights a 1M context window, multimodal support, and zero data retention.
