🐦 744B AI model on a 25GB laptop — Colibrì + disk-streaming MoE engines (no GPU)
Plain: a model that normally needs a server farm runs on a normal PC by keeping most of itself on your SSD and pulling in only the ~11GB it needs per word.
Colibrì — 744B GLM-5.2, ~25GB RAM, one 2,400-line C file, no GPU/Python — https://github.com/JustVugg/colibri
Same “don’t load what you don’t use” trick, more engines:
• KTransformers — full 671B DeepSeek on one GPU — https://github.com/kvcache-ai/ktransformers
• PowerInfer — hot neurons on GPU, cold on CPU — https://github.com/SJTU-IPADS/PowerInfer
• AirLLM — 70B on a 4GB card, one layer at a time — https://github.com/lyogavin/airllm
• prima.cpp — split a model across your phones + laptops — https://github.com/OpenCPIL/prima.cpp
• exo — home AI cluster from everyday devices — https://github.com/exo-explore/exo
• llamafile — whole model as one file that runs anywhere — https://github.com/mozilla-ai/llamafile
First run does a one-time weight conversion and thrashes the disk — normal, not a bug.
🌱 27B multimodal model on a phone — Bonsai 27B + 1-bit/ternary quantization stack
Plain: store each weight as just -1/0/+1 instead of a 16-bit number → file shrinks ~10× and the math gets cheap → a 27B model fits on a handset.
Bonsai 27B (Qwen 3.6) — 1-bit 3.9GB @ ~11 tok/s on iPhone 17 Pro, or ternary 5.9GB @ ~95% quality, full multimodal — https://huggingface.co/collections/prism-ml/bonsai-27b
• BitNet — 100B at reading speed on one CPU (reference impl) — https://github.com/microsoft/BitNet
• T-MAC — the low-bit lookup-table kernels underneath — https://github.com/microsoft/T-MAC

• Jan — offline ChatGPT app — https://github.com/janhq/jan
• LocalAI — drop-in OpenAI API on your own box — https://github.com/mudler/LocalAI
• MLX — Apple-Silicon native, unified memory = no VRAM wall — https://github.com/ml-explore/mlx
🎮 PS5 booting on PC — SharpEmu status + working emulators + static recompilation
Plain: run console games on a PC. Emulators fake the hardware; recompilers translate the game into native code that just runs.
SharpEmu — new PS5 emu (C#); boots real games to a video loop, runs small 2D titles. Boots ≠ plays — years from GTA6, but it’s the foundation — https://github.com/sharpemu/sharpemu

Static recompilation (game → native C, full speed, no interpreter):
• N64Recomp — N64 ROM → PC port — https://github.com/N64Recomp/N64Recomp
• XenonRecomp — Xbox 360 → C++ — https://github.com/hedge-dev/XenonRecomp
• xboxrecomp — original Xbox x86 → C — https://github.com/sp00nznet/xboxrecomp
• MiSTer FPGA — preservation in hardware, not software — https://github.com/MiSTer-devel/Main_MiSTer
🕵️ One-download OSINT lab — Trace Labs VM + username/email/phone recon tools
Plain: a ready Linux VM with every open-source-intelligence tool preloaded (built for legal missing-persons work); wipes its own data on exit.
Trace Labs OSINT VM — Sherlock, PhoneInfoga, SpiderFoot, sn0int, theHarvester, h8mail, Sublist3r, ExifTool, Steghide, Shodan CLI + Obsidian vault — https://github.com/tracelabs/tlosint-vm
Add the modern hunters:
• Maigret — one username across 3,100+ sites — https://github.com/soxoj/maigret
• Blackbird — username + email, fast — https://github.com/p1ngul1n0/blackbird
• Osmedeus — turn recon into a repeatable workflow — https://github.com/j3ssie/osmedeus
• WhatsMyName — the dataset every namechecker runs on — https://github.com/WebBreacher/WhatsMyName
Public info, legal use — that’s what the kit is for.
📤 No-server direct file transfer + P2P dial-by-key — PairDrop, iroh, Trystero, LocalSend
Plain: send files straight between two devices with nothing in the middle — no upload, no cloud, no size cap.
PairDrop — browser AirDrop for any OS; same Wi-Fi auto-connects, else a 6-digit code; self-hostable — https://github.com/schlagmichdoch/PairDrop
• LocalSend — native-app cousin of PairDrop — https://github.com/localsend/localsend

💡 Where this actually pays off — offline, blocked, delisted, air-gapped (5 real situations)
• 
No internet, still need AI — on a plane or dead zone, Colibrì/Bonsai answer from your SSD, not a server.
• 
API blocked or too pricey — run a 27B model straight off your phone, no account, no bill.
• 
Game delisted or console died — an emulator/recomp keeps the library you paid for alive on PC.
• 
Vetting a stranger from just a handle — one VM runs the whole recon kit, then wipes itself on close.
• 
Client site, USB locked, no shared drive — two browser tabs send a 4GB file directly, nothing uploaded.
