🚨 Bootcamps are charging $15k just to teach you how to call the OpenAI API. Meanwhile, this open-source curriculum just dropped 435 lessons to help you build AI from the ground up. It spans 20 phases and ~320 hours. But the best part is the philosophy: you don't touch PyTorch until you understand exactly what it’s doing under the hood. Here is the full stack: → Phase 0-2 (Foundations): Linear algebra and probability through code, plus classical ML from scratch. → Phase 3-6 (Deep Learning): Neural networks from first principles. No frameworks. → Phase 7-9 (Architectures): Transformers, Generative AI, and Reinforcement Learning. You implement attention yourself. → Phase 10-11 (LLMs): Build, train, and deploy large language models. → Phase 12-13 (Multimodal): Vision, audio, and MCP server integration. → Phase 14-16 (Agents): 42 lessons on agent engineering, including a custom ReAct loop in ~120 lines of pure Python. → Phase 17-19 (Production): Infra, deployment, observability, and safety. → Phase 20 (Capstones): 17 shippable projects. Every single lesson ships a real artifact: a prompt, a skill, an agent, or an MCP server. You don't just learn AI. You build it by hand.

I can’t believe @AnthropicAI compared their product to nuclear weapons 412 times and somehow that backfired. TRULY SHOCKING
The US government, citing national security authorities, has issued an export control directive to suspend all access to Fable 5 and Mythos 5 by any foreign national, whether inside or outside the United States, including foreign national Anthropic employees. The net effect of this order is that we must abruptly disable Fable 5 and Mythos 5 for all our customers to ensure compliance. Access to all other Claude models is not affected. We apologize for this disruption to our customers. We believe this is a misunderstanding and are working to restore access as soon as possible. Read our full statement: anthropic.com/news/fable-myt…

Fable 5 just got banned. Meanwhile, Chinese bros keep grinding. They built something ranked second right behind Fable. They’re going to catch up. Build something better than Fable. Then open source it.
Kimi 2.7 ranked 2nd after Fable 5 and before GPT-5 xhigh We have re-run our ErdosBench smoke test on 14 problems with Kimi 2.7, Qwen 3.7 Max, Grok 4.3 and compared it with the top performers from previous runs. Kimi 2.7 is amazingly good. More below.

Repo link → github.com/rohitg00/ai-engin… Shoutout to @ghumare64 for architecting this whole thing and giving it away to the developer community for free. It takes an insane amount of effort to build something this comprehensive. Drop a ⭐️ on the repo and start building!

Fable isn't the first. Back in 1999, the PowerMac G4 was so powerful that the Department of Defense banned its export for breaching the 1-gigaflop barrier Steve Jobs turned it into an ad.

🚨 @Karpathy predicted the power of the "LLM Wiki." Google just formalized it. Meet Open Knowledge Format (OKF): a vendor-neutral standard for giving foundation models the curated context they need. I can genuinely see this replacing Notion, Obsidian, or traditional wikis for developer teams, and the reason comes down to bookkeeping. Traditional wikis fail because humans inevitably abandon the tedious work of updating them. As Andrej Karpathy pointed out recently, LLMs don't get bored. They don't forget to update a cross-reference, and they can touch 15 files in a single pass. OKF standardizes the interoperability layer so agents can actually do that heavy lifting autonomously. Because the format is minimally opinionated, it doesn't dictate what you write, it just dictates how it's structured. You get: → Human-readable documents that live right alongside your code in version control → Cross-links that map out complex entity relationships without needing a graph database → A system that survives moving between different tools and organizations There is no complex compression scheme. No central registry. If you can cat a file, you can read it. If you can git clone a repo, you can deploy it. This is how we stop rebuilding context pipelines from scratch every time a new model drops. Announcement spec file in 🧵↓

US regulators with Anthropic employees this year
JUST IN: Andrej Karpathy, a top AI scientist at Anthropic, is reportedly barred from accessing the company’s most advanced AI model because he is not a U.S. citizen.

MANUALLY DRAGGING BOXES FOR ARCHITECTURE DIAGRAMS IS FINALLY DEAD There is a new open-source agent skill that turns raw codebases into cleanly routed draw.io diagrams without you placing a single coordinate. The project, drawio-skill, runs directly inside Claude Code, Cursor, or Copilot. Instead of opening a blank canvas, you just ask your agent to map the repo. Here is what it actually does: → Extracts the module structure (supports Python, JS/TS, Go, Rust) → Uses Graphviz for auto-layout and routing → Drops redundant edges so the graph stays readable → Builds native, editable draw.io files But the standout feature is visual self-checking. Once it generates the diagram, the agent "looks" at the resulting PNG. If it sees stacked edges or clipped text, it auto-fixes the layout across up to 5 iterative rounds. It runs from a single file. No MCP server. No background daemon. Best part? It's 100% free and open-source. repo link in 🧵↓

🚨 NVIDIA JUST OPEN-SOURCED ONE OF THE MOST IMPORTANT AI UTILITIES OF THE YEAR Right now, developers are downloading third-party "skills" straight off GitHub for their AI agents. But an AI skill is not just a text prompt. It’s executable code that runs with your system privileges. A skill you grab to save ten minutes can read your environment variables, lift your API keys, and quietly send them to an external server. Recent research shows 26.1% of public skills carry vulnerabilities, and over 5% are outright malicious. NVIDIA’s new release, SkillSpector, closes this gap. It’s an Apache 2.0 licensed security scanner that answers one question: is this skill safe to run? Here is how the pipeline works: → You point it at a GitHub link, local folder, or a single SKILL.md file. → Pass 1: A fast static scan flags credential harvesting, prompt injections, and checks live CVE data. → Pass 2: An optional LLM pass evaluates the semantic intent of the code to clear out false positives. At the end, you get a 0 to 100 risk score and a clear verdict: Safe, Caution, or Do Not Install. It currently scans skills for Claude Code, Codex CLI, and Gemini. Worth running before you blindly trust the next agent skill you find online. repo link in 🧵↓
