One C++ binary replaces your whole Python diffusion stack

stable-diffusion.cpp runs Stable Diffusion, Flux, Qwen Image, Wan, and Z-Image with zero Python installed. No PyTorch, no CUDA toolkit rituals, no dependency hell — just a compiled binary and a model file.

It's built on ggml, the same tensor library behind llama.cpp, so it runs everywhere: CPU, CUDA, Metal, Vulkan, OpenCL, SYCL. LoRA, ControlNet, ESRGAN upscaling, and GGUF quantization all work out of the box, and support for new models lands almost every week.

Generating an image takes one line: point sd-cli at a checkpoint and a prompt, and it writes the file. No server to run, no notebook, no setup script to debug at 2am.

RAG isn't dead — it just went quiet where a wrong answer costs real money

Million-token context windows made people call retrieval-augmented generation dead. The data disagrees: retrieving a narrow slice of a knowledge base costs about 1,250x less per query and runs 45x faster than pasting the whole corpus into a prompt. Long contexts also lose 30%+ accuracy when the fact sits buried in the middle instead of the edges.

Legal tools like Harvey and Westlaw AI still ground every answer in real case law, avoiding citations to cases that don't exist. Anthropic's own "Contextual Retrieval" cut failed searches by 49%, 67% with reranking, just by prepending generated context to each chunk before indexing.

The unusual part: it leaves a paper trail. Traceable chunks let a team show which document backed an answer — something a single giant prompt can't offer, and something compliance-heavy industries won't ship without.

Your AI agents get a space station, and every room is a real permission

StarNet is a local-first desktop harness for running actual AI agents, not chat logs. Build a crew, give each agent its own workspace and bounded permissions, and run several at once — real model calls, real tools, real cost, no simulation underneath.

What's unusual: the interface never claims state it can't prove. The pixel-art station is the literal workflow — a room is a capability-scoped team, a hallway is an authorized handoff, a placed object is a real permission grant. Draw the layout, and that's what runs.

Bring your own OpenRouter key, sign in with a provider, or skip the bill with a local Ollama model. Wire agents to Telegram, Discord, or Slack to reach them remotely — finished work lands in an OUTBOX as real files, not scrollback to dig through. Clone it and run the sidecar with plain Node — no install needed.

20 Claude Code tabs open and no idea which one is doing what? Hire a company instead.

Paperclip is an open-source Node.js server and React UI that turns a pile of loose AI agents into an actual org chart. Every agent gets a role, a boss, and a budget instead of running unsupervised in some terminal you forgot about.

Define a goal, hire the team — CEO, engineers, marketers, any agent from any provider, OpenClaw, Claude Code, Codex, Cursor, or a plain HTTP/bash process — and Paperclip assigns tasks, tracks costs, and stops agents cold when their budget runs out. Every decision gets logged, so nothing happens off the record.

It's written in TypeScript, self-hostable, and runs from a dashboard you can check from your phone.

Anthropic's cheapest Claude model is 10x cheaper than its priciest — and sometimes wins anyway

Most teams grab whatever model just launched and use it for everything, then eat the bill without checking if it helps. Anthropic, OpenAI and Google all publish the opposite advice: pick the model per task, not by launch date.

Anthropic's own benchmark shows a mid-tier model matching the flagship's coding score at about a fifth of the cost per task. A coordinator plus parallel cheap workers beat a single top model by 47-55% on cost and 7-9x on speed. OpenAI ships three tiers per release; Google calls its cheapest tier "frontier-class" for high-volume work.

Nothing gets retired to force upgrades — older generations stay supported on the API for over a year, right next to the newest. The smaller, cheaper model is a standing option, and often the objectively better pick.

Give every AI agent its own keys — and let it work like a teammate, not a bot

Buzz is a self-hostable workspace, built in Rust, where humans and AI agents share the same rooms. Chat, code review, and CI usually live in separate tools, with agents that have no identity and no audit trail. Buzz puts every message, patch, review, and workflow step into one signed event log, so a human and an agent leave the same kind of trail.

Open a feature branch and a channel appears for it automatically — patches, CI results, and approvals land in that room. Ask "have we seen this error before?" and an agent searches history and posts real threads back. Agents get their own keys and channel memberships, so you can let one triage a bug without handing it blanket access.

Try it as a packaged desktop app for macOS, Linux, or Windows pointed at your own relay, or deploy a relay in one click and self-host the whole thing.

One MCP server to drive iPhone and Android apps — no XCUITest, no Espresso

Automating a mobile app usually means two codebases: XCUITest for iOS, Espresso for Android. Mobile MCP replaces both with one platform-agnostic interface, so an agent can tap through a native app without anyone learning iOS or Android internals.

It reads the accessibility tree instead of screenshots, so it gets structured, deterministic data on UI elements — faster and cheaper than a vision model, with a coordinate-based fallback when needed. The same tool set covers simulators, emulators, and real devices, and plugs into Claude Code, Codex, Gemini, and other MCP clients.

Install app, tap through screens, pull device logs or crash reports, set GPS location — full device control, not just taps. No simulator on hand? Point it at a real device in the cloud instead.

523 lessons to turn "I use AI tools" into "I build AI systems"

84% of students already use AI tools. Only 18% feel ready to use them professionally. AI Engineering from Scratch is a full curriculum built to close exactly that gap, from linear algebra to shipping production agents.

The unusual part: nothing here is a slide deck. 20 phases, roughly 342 hours of material, and every single lesson ends with a reusable artifact you keep — a prompt, an agent, an MCP server, a skill — written in Python, TypeScript, Rust, or Julia depending on the lesson. You read the idea, type the code yourself, run it from the repo root, and keep the output as evidence before moving on.

Clone it, run the setup verifier, then a dependency-free first lesson that shows a matrix-vector product is literally the operation inside a neural network layer. Free, open source, MIT licensed, no signup.

Windows games on an un-jailbroken iPhone, for real

Madeira runs actual x86-64 Windows PC games on iOS without jailbreaking — no exploit, just an app you sideload.

Under the hood: Wine (ARM64EC) for the Windows layer, FEX-Emu translating x86-64 to ARM64, and DXMT turning D3D11 into Metal — fused into one Mach process, with wineserver running as a thread instead of a separate process. Thumper and ULTRAKILL are fully playable; Marvel Cosmic Invasion has reached gameplay, still rough.

JIT needs a debugger attached, so it can't ship via the App Store — sideload it and attach with a tool like StikDebug. A free Apple ID signs it, though the profile expires weekly, meaning a rebuild every 7 days; saves and prefixes survive reinstalls.

Compile TypeScript straight into a native binary — no Node, no JS engine

Shipping a TypeScript CLI or server usually means bundling Node and a JS engine too. scriptc skips that — it compiles TypeScript and JavaScript straight to C, LLVM IR, native assembly, or a standalone executable, using the real TypeScript compiler for parsing and type checking.

The unusual part is how many stops you can make along the way: halt at C, at LLVM IR, at a relocatable object, or go straight to a Node-free executable. Static builds carry only a small native runtime, and coverage reports exactly how much compiles statically, flagging every dynamic site. Code leaning on npm packages or any can opt into an embedded quickjs-ng engine via --dynamic.

Install with npm install -g scriptc, then scriptc build hello.ts -o hello for a running executable. It also compiles supported Node APIs like node:http and can target WebAssembly via WASI. Still experimental, across macOS, Linux, Windows, and WASI.

Hindsight gives AI agents a memory that learns, not just recalls

Most agent memory is a chat log with search on top. Close the session and the agent starts from zero. Hindsight is built so agents improve across sessions instead of only replaying old context.

The API is three calls: retain stores facts, recall searches them, reflect answers with what the agent has learned. It aims to fix the gaps of plain RAG and knowledge graphs. It reports state-of-the-art results on LongMemEval, reproduced independently by Virginia Tech.

Try it: one Docker command starts the API and a UI. It works with 25+ LLM providers, including local Ollama, and has Python, TypeScript and Go clients, plus an MCP server. MIT licensed.

PipePipe: a NewPipe hard fork with SponsorBlock and real dislikes built in

An open-source Android app for browsing YouTube and other services without the official client. It skips sponsored segments (YouTube and BiliBili), restores dislike counts via ReturnYouTubeDislike, and shows original, non-localized titles.

Your feed gets cleaner too: filter out items by keyword or channel, block Shorts and paid videos, and use advanced search filters. Playback adds swipe-to-seek, long-press speed-up, a sleep timer, AV1/VP9, a background music mode, and live chat as danmaku-style overlays. You can download whole playlists at once.

The unusual part is that it is a hard fork from 2022. It neither pulls from NewPipe nor pushes back, so fixes and features ship on its own schedule. Login is optional, and the cookie is only used for the scenarios you enable.

Try it: install from F-Droid or IzzyOnDroid.

One email can hijack your AI assistant, and the victim never clicks

Prompt injection: text an AI model reads can carry instructions, and the model obeys them. To a language model, your orders and an attacker's text are both just plain text. It can be typed into a chat, or hidden in an email, web page or document that an agent reads by itself.

The odd part: it was named after SQL injection in 2022, but SQL injection has a fix (parameterized queries) and this one doesn't. EchoLeak (CVE-2025-32711) pulled data out of Microsoft 365 Copilot with a single crafted email and zero clicks. OpenAI says the problem for AI browsers is "unlikely to ever be fully 'solved'". OWASP ranks it risk #1 for LLM apps.

To try it: read the original write-up, where a translation bot ignores its job and prints "Haha pwned!!". Then apply the basics: least-privilege access, human approval for risky actions, untrusted content kept separate.

A 10.5 GHz phased array radar with schematics, PCBs and firmware, all open

Phased array radar is usually closed, expensive hardware. AERIS-10 publishes the whole stack: schematics, PCB layouts, FPGA and STM32 firmware, and a Python GUI. Hardware is CERN-OHL-P, software is MIT.

Sixteen elements steer the beam electronically, ±45° in azimuth and elevation, and a stepper motor adds a 360° mechanical scan. An on-board FPGA does pulse compression, Doppler FFT, MTI and CFAR, so detection runs on the board, not on your laptop.

Two builds: AERIS-10N with an 8x16 patch array for about 3 km, and AERIS-10E with a 32x16 slotted waveguide array and 10 W GaN amplifiers for up to 20 km. GPS and IMU data tag each detection, and the GUI plots targets on a map.

It's alpha and some features are still in progress, so expect to hack. Start with the repo and pick a version.
