THIS GUY HAS BEEN BUILDING AN ENTIRE GAME WITH CLAUDE OPUS FOR 15 WEEKS. THE AI WRITES THE CODE, BUILDS THE CITIES, CREATES 3D ASSETS, AND EVEN EDITS THE TRAILERS. it's called Nightshoal, a Godot game set in a 1920s world of harbours, fishing boats, bridge cities and black markets. he's been building it with Claude Opus, posting weekly progress on Reddit, and there's already a free playable demo. what's insane is how much of the actual game is being built by AI. the world has: a massive bridge city with moving traffic, trams and a lighthouse a sun that actually moves across the sky, changing shadows and water reflections a moon that takes over at night, with buildings lighting up an entire black market with steamers, warehouses, piers and fishing boats harbours, docking scenes, weather, achievements and more and here's how he builds it: Claude Opus 5.5 writes basically all the code. it also controls Blender through MCP to build city layouts, buildings and fix 3D models. TripoAI generates the 3D assets. he makes images showing all four sides of an object, Claude splits them up, Tripo turns them into a model, and Claude cleans it up in Blender. OpenAI's image API generated 24 reference mockups of the city, showing 6 different views at 4 times of day. then he built something called a Gauntlet-Loop. AI critic agents blindly compare screenshots of his actual game against those mockups and keep improving the game until it wins. after 10 rounds, 31 out of 33 pieces beat the reference images. even the performance work is done by Opus. this week it found a map using 4 GB of graphics memory because it was being drawn at double size. Opus helped bring that down to 0.3 GB and cut startup time from 26 seconds to 13. the first harbour docking freeze went from almost 2 seconds to 0.2. he also has another system called Jev that decides how much reasoning effort Opus should spend on each task. the crazy part? he spent around $1,100-$1,150 on AI tools just this week, including four Claude Max plans. 15 weeks in, he's already got a playable game, entire AI-built environments, dynamic lighting, weather and a working world. and he's still building the actual gameplay. links below 👇

People posting Jensen's wife to justify his cheating are disgusting.

I genuinely don't understand what is wrong with so many tech CEOs. We keep putting these people on pedestals because they build billion-dollar companies, yet some seem to have never developed the most basic qualities of character, integrity, and self-control. Being exceptionally intelligent doesn't automatically make you a good human being. And changing the world doesn't excuse failing the people closest to you.
a good man can do a bad thing. Jensen Huang has done enormous good for the world through NVIDIA and advancing life-saving superintelligence technology we don’t erase that because he was unfaithful. one of my heroes is Dr. Martin Luther King Jr. we don’t discount his civil rights leadership because of his various well-documented extramarital affairs. i don’t mean to excuse any of it. he did a dumb, stupid, and hurtful thing. marriage is a sacred covenant and he damaged his family. but how many of you could withstand the pressure of a full nation-state apparatus hellbent on bringing you down? we have to be able to hold two ideas in our heads at the same time: the personal failure and the larger contribution.

Vibecoders, I'm begging you. Do this once and you'll realize how much better your code could be. Open your messiest project and paste this into Claude Code or Codex: "Find all of the implicit state machines in my app. Make the best decision that will elevate all three: the user experience (UX), developer experience (DX), and agent experience (AX) always, without breaking anything."

THIS GUY MADE ANDROID AND MAC SWAP FILES WITH NO CABLE, NO ACCOUNT AND NO CLOUD. YOU JUST TAP THE PHONE ON THE NOTCH it's called TapDrop and it's open source under MIT how it works: the phone flashes its screen, the light sensor next to the MacBook notch picks it up, and the mac grabs whatever is on the phone's screen what gets sent stays on your wifi and is end-to-end encrypted. there's nothing to sign up for the proof: he tried it on pixel, samsung, vivo, oppo and nothing phone and says it worked on all of them setup: > install the mac app > install the android app (android 13+) > any mac with a notch works what you can send: > pdfs, links, original photos and videos > any type of file > sms otps, copied straight to the mac > mac to phone works too the funny part: it started because he didn't want to email a pdf to himself one more time file transfer used to mean cables, accounts and a cloud in the middle now it's a phone touching a screen cutout links below 👇

The problem is that LLMs generate plausible OAuth implementations, not necessarily protocol-correct ones. MCP auth is especially unforgiving. One wrong assumption about discovery, PKCE, or token audience validation breaks the entire handshake. Have you tried MCPJam? It has an OAuth debugger that traces the actual flow: github.com/MCPJam/inspector
LLMs are still SO bad at building tools for agents. Every time I try to make Opus set up an MCP authentication path, it makes horrible assumptions and builds something that straight up doesn't work

Say whatever you want, but Jensen is a piece of shit. He cheated on his wife after 40 years, so why wouldn’t he cheat on anything else? I’m done with people acting like this is normal. Stop normalizing this. He grew Nvidia, sure, but he’s still just a horny old goat. Fuck that.

THIS GUY CUT THE SCREENSHOTS OUT OF HIS COMPUTER-USE AGENT. THE MODEL JUST PICKS A NUMBER it's called ywza and it's open source most computer agents send the model a fresh screenshot at every step. ywza describes each window as a numbered list of elements instead: buttons, fields, text the model says "click 14" and that's it why that matters: > far fewer tokens per step > less for the model to reason about > still works on any window, whatever technology it's built with > can still ask for a screenshot when it really needs one the numbered list comes from smart detection that runs on the window itself, so it doesn't care if the app is Qt, a terminal or something old it runs as a small background agent on the PC you want to automate, and it works in the terminals you already have open it's written in Rust using pictures to read a screen was always the expensive way turns out a menu is easier to pick from when somebody numbers the items links below 👇

THIS GUY HAD OPUS 5.5 BUILD A 3D HUMAN BODY YOU CAN TALK TO. TELL IT WHAT YOU ATE AND WATCH IT PLAY OUT INSIDE YOU it's called Bodylang and it's open source, MIT licensed you type what you ate or did, or just ask it anything, and a minute-by-minute physiology model plays it out on the body. the organs light up as it explains what's happening the idea came from biology class: 2D pictures in a textbook are the least clear way to learn how a body works, so he made one you can poke at what's in it: > a male and a female body model > organs, muscles and vessels you can see in 3D > an animated close-up drawing for each organ > chat, model and track your body through the day the chat part runs on your existing Claude Code subscription, mostly on Haiku and Sonnet, so it's generally very cheap not every body system is in yet, it's early. but the whole thing already looks like an illustrated textbook that answers back biology used to be a diagram you memorized now one guy and opus put a body on screen and you just ask it what your lunch is doing links below 👇

love this idea.
Claude Code can design furniture part by part and then give you a bill of materials to order each part and put it together yourself And way cheaper than big interior brands sell you their furniture Furnishing my house I discovered how absolutely insane prices are for the most basic cheap materials put together with a fancy brand tied to it One shop had a sofa for $30,000 😂 I think with Opus 5.5 and other models easily operating 3d programs like Blender and FreeCAD (both free) it makes more sense to cut out the middle man and go straight to suppliers and design and build your own furniture Which in a way makes customers more powerful (they can get exactly what they want and usually for cheaper without the markup) Anyway @theannalux designed this table from scratch, she's not a furniture designer, not a coder, she just had an idea of a style and worked with Claude Code in the terminal (far superior to the app I will keep saying this) If you design your own furniture and buy the raw materials directly, you can save 85% compared to premium brands like Poliform That means the $30,000 sofa becomes $4,500! And the $8,000 dinner table becomes just $1,200! You can see where the idea comes from that AI will make everything 5x to 20x cheaper, and it's already starting!

THIS GUY GAVE EACH AI AGENT ITS OWN FULL LINUX VM. IDLE, IT USES ABOUT 45 MB OF HOST MEMORY it's called Terrarium and it's open source, Apache-2.0 not a container sharing your kernel. every box is a real VM with its own kernel, and the network rules are enforced from outside the VM, so nothing inside can talk its way past them he wanted something narrow and auditable, so he wrote a small custom VMM on parts of rust-vmm under the hood: > filesystem, block and network devices run as WebAssembly components, each with its own memory limit > the VM process itself has no network access > connections go through a separate broker that checks them against your recipe > Linux builds get per-role seccomp allowlists, generated by static analysis of the binaries the whole thing ships as one executable with the VM parts, a Linux kernel and an Alpine base system bundled in boxes are persistent, so tools and files survive restarts. you can attach from several terminals, detach without stopping the agent, and reconnect later the surprising part: even the code that fakes the hardware is sandboxed most agent sandboxes trust the wall this one sandboxes the wall too links below 👇

THIS GUY MADE HIS MCP SERVER CATCH A TOOL THAT LOOKS SAFE WHEN YOU APPROVE IT, THEN QUIETLY CHANGES ITS RULES LATER it's called opentel-mcp, and v0.18 is a security release the attack is called a "rug pull". an AI tool passes review with a harmless description, then the description or schema (the list of inputs it takes) gets swapped after you stopped looking so the library fingerprints every tool definition with SHA-256 and checks it again at runtime. same text, same fingerprint. change one word and it shows what gets hashed: > name > description > input and output schema > annotations how you use it: > pin the known-good hashes in the config > any change, addition or removal gets flagged > a mismatch from a pinned hash raises a high-severity event > in dev mode it prints your current hashes as a copy-paste snippet it's detection, not prevention. it tells you the tool changed, it doesn't block the call the catch with most dashboards is they watch whether a tool worked, not whether it's still the same tool you used to approve a tool once and trust it forever now a hash does the nagging for you links below 👇

THIS GUY TRAINED A 1.1 GB MODEL ON AN RTX 4060 LAPTOP TO SAY "NOT FOUND" INSTEAD OF MAKING THINGS UP it's called Obsessive-1.7B, a fine-tune of LFM3-1.7B with exactly one job it's a subagent, not a chat model. a bigger model hands it a factual question, it calls web search once, and it answers with a short value, a word-for-word quote and the URL. if the answer isn't in the results, it says "Not found in the search results." example: asked who was the second woman to win the Turing Award, it answers Barbara Liskov, quotes the line, and links the Wikipedia page the training: > LoRA rank 16, about 9k tool-calling conversations > search results are Wikipedia and FineWeb pages > every answer and quote checked to appear verbatim > about a quarter of the examples teach "not found" > a local qwen model helped prepare the data and questions the test: 131 held-out SimpleQA questions, and in 29 of them the answer was removed from the results on purpose the honest part: on live Wikipedia search the base model actually gets more answers right, but 62% of the time it runs out of turns and returns nothing. Obsessive only states what it can quote it still says "not found" for about 1 in 10 answers that are really there, and it only handles one question per conversation everyone trains small models to answer more this one is trained to shut up when it can't prove it links below 👇

THIS GUY HAD CLAUDE PULL THE AI MODEL OUT OF AN ORAL-B TOOTHBRUSH APP AND SHRINK IT 100X WITH BARELY ANY LOSS the iO5 has a motion sensor inside that tells the app which part of your mouth you're brushing. the guessing is done by a 1.2M parameter neural net, a bi-directional GRU (a net that reads a sequence of readings forwards and backwards) claude extracted that model from the companion app, then tested it on a public dataset: ~63% accuracy on the mouth zone, where random guessing gets ~6% then the guy asked claude if it was overkill the ablation (remove a piece, see what breaks): > most of the value came from just the last ~10 seconds of motion > so a giant recurrent net wasn't needed > claude used real examples to make a larger synthetic dataset > it trained a bunch of small models on it the result: a small CNN hit ~61% and is 100x smaller he also has a replay of one dataset session running on a live 3D twin of the brush, in the video the toothbrush company shipped a big model for a job a tiny one does almost as well now one person and claude took it apart in a side project links below 👇

THIS GUY GOT QWEN3.8-27B RUNNING ~2X FASTER THAN LLAMA.CPP ON ONE 3090, AND IT GIVES THE EXACT SAME TEXT WITH OR WITHOUT SPECULATIVE DECODING it's called qwen38-megakernel and it's open source under AGPL-3.0 it's an engine for one 24 GB card, with OpenAI and Anthropic style APIs so coding agents can talk to it the numbers from the repo: > 1.8 to 2x llama.cpp's decode speed > full 262k context on one 3090 > 77.8 tok/s at full depth > 6/5-bit KV cache, with the last 2,048 tokens kept at 8-bit the trick is that speed settings can't move the output: > greedy token ids identical with 0, 4 and 7 drafts, across all 282 test outputs (129,511 tokens) > sampling keeps the no-draft distribution, checked with chi-square and PIT tests > windows and linux builds give the same tokens llama.cpp didn't pass the same check. 113 of the 282 outputs changed with drafts on it also covers the cache. in 20 two-turn chats, llama.cpp's second answer differed when the cache was reused in 20 of 20. this engine: 0 of 20 the honest line from the post: it matches itself, it is not bit-identical to llama.cpp the usual deal is you pay for speed with a little drift this guy's deal is you pay nothing, and you can prove it 👇

THIS GUY GOT 215 TOK/S ON CODE OUT OF A 2-BIT DEEPSEEK RUNNING ON EIGHT V100S FROM 2018. 524K CONTEXT, ALL EXPERTS IN VRAM it's an open source repo called Volta-sPLIt, a port of 1Cat-vLLM work to 8x V100-SXM2 the poster is a lawyer, and a few days earlier the same model ran at 36-38 tok/s on four cards. then came custom kernel work, prefill tuning, and four more cards the speed, measured with thinking off: > code: 215 tok/s at 1K, 200 at 32K, 183 at 128K, 160 at 256K > JSON: 196-209 from 1K to 128K > legal writing: 118 at 1K, 111 at 128K, 103 at 256K why code is faster: the model guesses five tokens ahead each round, and code is easy to guess. 3.6-3.8 guesses land per round on code, about 1.6 on legal text the box: > 8x V100-SXM2-32GB on two NVLink boards > Threadripper PRO 3945WX, 256 GB DDR4 > 150 W per card > 110 GB of Engram tables live in system RAM, about 0.12 ms per round to gather the slow part is the front: prefill runs about 2,200 tok/s at 128K, so the first token takes 59 s there and about 2 minutes at 256K everyone says you need a new rack of H100s for this turns out a pile of 2018 cards and a lot of patience gets you most of the way links below 👇

What if OpenAI and Anthropic are already exploring the most profitable illegal business in AI? Using frontier models to discover critical zero-day vulnerabilities and secretly selling them to the highest bidder. The potential profits are insane. And how would anyone find out? I don't trust these money-minded corporations one bit.
Introducing GPT‑6 Cyber: a major advance in security research that pairs stronger capabilities with better model alignment. The model powered the Linux kernel research we announced yesterday, and security teams at companies like Mozilla, Palo Alto Networks, Calif, and Cisco—alongside our own at OpenAI—are already putting it to work. GPT-6 Cyber is available to select Daybreak Red customers and we are expanding access over time. openai.com/index/introducing…

Someone built an insanely useful tool for running 10+ AI coding agents in parallel. Each agent gets its own Git worktree, so they don't mess with each other's code. Launch agents, switch tasks, merge changes, and clean up with simple commands. It's called Worktrunk. Open source, written in Rust, with 11k+ GitHub stars.
