Local AI Weekly #6: If You Can Reverse Engineer It, It's Open Source! A weekly AI newsletter reported that Perplexity added the MIT-licensed REA (Reverse Engineer Anything) MCP server to its Computer agent as a free `/reverse-engineer` command through 31 October, and that Meta released Muse Spark Open, an 816B-parameter model with 42B active parameters and a 1M-token context that requires two Mac Studios with 512 GB each to run. The newsletter also flagged that fake REA repositories are already distributing malware, so the tool should be installed only from the official repo or npm package, and noted Muse Spark Open ships under the limited-commercial "Muse Model License" — open weights, but not open source. What I realized in the past week or so is that if you can reverse engineer it, any software is open source software. Not in the license sense, of course. But AI agents are getting good at reading binaries, tracing what an app does and rebuilding it. Last issue, we had the Craft tools cloning Microsoft Office. This week, there are more office clones, a viral repo that reverse engineers "anything", and people taking back control of their smart TVs with the help of AI. The source code is no longer the wall it used to be. Whether that's a good thing depends a lot on which side you are on. 🧪 On my desk I have enjoyed using Myna for voice based input on Ubuntu 26.04 yes, it can be installed on 26.04 . The performance is surprising good. Next, I will be trying a few more such voice input tools, starting with SpeakoFlow https://github.com/AbhishekBarali/SpeakoFlow?ref=itsfoss.com . 🔍 Discover AI tools REA Reverse Engineer Anything https://github.com/morluto/rea?ref=itsfoss.com is the repo of the week. It's an MIT-licensed MCP server that lets AI agents inspect native binaries, Electron apps, Android APKs, firmware and more. Deep native analysis needs proper reverse engineering tools like Ghidra https://itsfoss.com/nsa-ghidra-open-source/ . Analysis runs locally, but your agent's model provider still sees what it finds. Also, fake REA repos are already serving malware, so install it only from the official repo or npm package. Graphify https://github.com/Graphify-Labs/graphify?ref=itsfoss.com is reverse engineering for your own code. It turns a codebase, docs and PDFs into a knowledge graph your coding agent can query. Code is parsed locally with tree-sitter, and GRAPHIFY BACKEND=ollama keeps the rest local too. It's a Plan https://github.com/croffasia/itsaplan?ref=itsfoss.com is a self-hosted Linear/Jira alternative where AI agents get a role and pick up issues like any team member. External agents run on your machine and hand tasks to Claude Code, Codex or opencode. In early stages for now. 🏢 The office clone wars Mandrake Linux creator Gaël Duval is behind ElixirOffice https://itsfoss.com/news/elixiroffice-euro-office-fork/ , a Microsoft Office look-alike built on Euro-Office components. The code was written by LLM agents, with tests and reviews on every change. It's AGPL-3.0 and in beta. Then there is Ely Office https://office.elygpui.com/?ref=itsfoss.com , six offline desktop apps for documents, sheets, slides, PDF, Git and Markdown. And BetterOffice https://github.com/openooxml/betteroffice?ref=itsfoss.com , which we covered last week, now has its Apache-2.0 source under the openooxml org on GitHub. Meanwhile, Perplexity added REA to its Computer agent as a /reverse-engineer command, free until 31 October. Its demo clones included Photopea, Audacity and... LibreOffice Calc. Yes, reverse engineering an app that is already open source LOL . 📺 Your TV, your rules My favorite story of the week. Android TV owners are using AI to debloat their smart TVs https://itsfoss.com/news/debloat-smart-tv/ . The agent connects over ADB, lists installed packages and disables ads, telemetry and preinstalled junk. People report faster TVs. A related project does the same for Fire TV. This is the "reverse engineering" idea at its most useful. You don't need to be an Android developer anymore to fix the device you paid for. 📡 Open Model News Meta released Muse Spark Open https://research.meta.ai/blog/muse-spark-open?ref=itsfoss.com , an 816B model with 42B active parameters and a 1M-token context. The headline says it "runs on Macs". But that actually means two Mac Studios with 512 GB each. Not the kind of hardware normies like me can afford. Also note the licence. It's the "Muse Model License" with limited commercial terms. Open weights, yes. Open source, no. 👀 Big Tech Watch NVIDIA RTX Spark laptops https://nvidianews.nvidia.com/news/nvidia-rtx-spark-pcs-available-today-a-new-beginning-for-windows-pcs?ref=itsfoss.com went on sale on 16 October, starting at $2,599, from ASUS, Dell, HP, Lenovo, Microsoft and MSI. The chip pairs a Blackwell GPU with a Grace Arm CPU and up to 128GB of unified memory, enough for bigger local models on a laptop. Two catches. The 128GB is only on the top configuration, and the lower tier tops out at 32GB. And these are Windows on Arm machines, with no word on native Linux support yet . Google Research open sourced Harness² https://github.com/google-research/harness2?ref=itsfoss.com , a framework that improves the harness around a model prompts, tools, memory, skills without touching its weights. It's Apache-2.0 and uses OpenCode by default. Model runs are configured for Vertex AI, and I see no documented local model path yet. Anthropic says Claude Code now gzips the conversation https://x.com/ClaudeDevs/status/2111209208012210409?ref=itsfoss.com it sends on every turn, and cloud sessions start as soon as you begin typing. It reports up to 3x faster time to first token for local Claude Code sessions, compared with August. The billion-dollar AI speedup came from gzip, a free and open source software tool from 1992. 🗂 AI Jargon: Clean-room design How do you copy software legally? Clean-room design. One team studies the original app and writes down only what it does: the behavior, the file formats, the interfaces. A second team, which has never seen the original code, builds a new app from that description. That separation is what protects the clone from copyright claims. It's how the PC BIOS was cloned in the 1980s and that's how Compaq became a popular PC brand. AI agents blur this neatly. The same agent that reads the binary often writes the new code. Whether that still counts as a clean room is a question lawyers will be busy with for a while. 😂 Meme ⚡ Quick Tip: Back up before an agent touches your TV Before you get too excited and let an agent debloat your Android TV, save the package list first: adb shell pm list packages tv-packages.txt Ask the agent to use pm disable-user instead of uninstalling. A disabled package comes back with adb shell pm enable
