What Do Q4 and Q8 Mean? I Squeezed One AI Into 9 VersionsSame AI, nine sizes. The first seven all knew the capital of France.
OpenAI and Claude Just Disproved a Famous Math Conjecture. Is P = NP?Did AI just solve P vs NP? Not quite.
Is AI Really a Black Box? I Opened Up NVIDIA's NemotronI found a "know this person / don't" direction inside NVIDIA's Nemotron 3.5 Bolt. Turn the knob and see what it really said at every step.
What Is a Reasoning Model? I Read the AI's ScratchpadThinking off: wrong, five times in a row. Thinking on: ten quiet seconds, then right every time 🤔 So I opened up the scratchpad to see what it was actually doing in there.
Fine-Tuning vs RAG vs Prompts: What Actually Teaches an AI?If you paste the same wall of instructions into AI every single time... same.
Why Does AI Hallucinate? I Asked It the Same Question 3 TimesSame question, three tries, three different PhD titles... all said like facts, all made up 🙃 The sneaky part is that every piece of the fake answer was real.
Does ChatGPT Actually Remember You? How AI Memory WorksChatGPT forgets you in a new chat, then remembers you hate cilantro. Here's where AI memory actually lives.
Why Is Claude Code So Good? It's the HarnessSame model, only the harness around it changed, and the score went from 58% to 76%. A CLAUDE.md / AGENTS.md instructions-file template to copy, and a little lab where you remove one harness part at a time.
What Are Claude Skills? It's Just a FolderClaude Skills (Agent Skills) explained in plain English: one folder, one SKILL.md, and a clever way of reading it. Open up a skill and there's one file inside, a few dozen lines of text.
Inside an NVIDIA H100: What's Actually in an AI ChipFrom the module down to a single transistor, every number checked against NVIDIA's whitepaper and spec page. The teardown animation runs in your browser; the prompt that made it is here to copy.
I Tried Prompt Injection on Opus 5.5, GPT-6 and QwenOne line of invisible text on a web page can make the AI that browses and reads email for you start working for someone else. That's prompt injection.
Claude Opus 5.5 vs GPT-6 Astra: Do AI Benchmarks Even Matter?What AI benchmarks actually test, why the #1 model on the leaderboard isn't always the best one for you, and how to run your own test. I typed half of a test question, and both Claude Opus 5.5 and GPT-6 Astra finished it word for word, then told me it was question #1 of the GSM8K test set.
What Is a Diffusion LLM? The AI That Doesn't Write Word by WordChatGPT writes one word at a time. A diffusion language model writes the whole answer at once and sharpens it, round by round.
How Does AI Image Generation Work? It Starts With Pure StaticAI doesn't draw pictures stroke by stroke. I ran an open-source image model on my own PC, saved all 8 steps of it turning TV static into a cat, and used them to explain diffusion models.
What Does 35B-A3B Mean? Mixture of Experts ExplainedThose "35B-A3B" names on every new open model, decoded: what Mixture of Experts (MoE) is, why a 35-billion-parameter model only uses 3 billion at a time, why that makes AI cheaper, and how it fits on a phone.
What Is AI Distillation? Your DeepSeek R1 Isn't Really R1A big AI model teaching a small one: what "distillation" actually is, and why AI labs keep fighting about it. If you installed DeepSeek R1 7B with Ollama, you're actually running Alibaba's small Qwen model, trained on 800,000 worked examples written by R1.
How Does AI Control Your Computer? It Only Sees ScreenshotsAI agents can now click, type and fill in forms on their own. But the AI never watches your screen move: it sees one screenshot at a time.
What Is MCP? The USB-C Port for AIWhy one AI can open your calendar and another can't: MCP, the Model Context Protocol, explained in plain English. Same Claude, same question.
What Is Jev? The $7.5B AI That Can't TalkJev can't chat, can't write code, can't even finish a sentence, and it's worth $7.5 billion. Jev is a decision model: an AI that only answers multiple choice.
What Is an AI Agent? Chatbot vs Agent vs WorkflowA chatbot tells you the steps. An AI agent does them.
What Is RAG? Why ChatGPT Didn't Read Your Whole PDF (Explained Simply)Drop an 80-page contract into ChatGPT, ask about the late-payment penalty, and three seconds later it answers with the page number. It didn't read all 80 pages: it pulled a handful of snippets and never saw the rest.
What Are Tokens in AI? Why ChatGPT Couldn't Spell Strawberry (Explained Simply)Paste any sentence and watch it get cut into tokens, the blocks ChatGPT actually reads. The tool from the video on why ChatGPT couldn't count the R's in strawberry.
