GPT-5.4 Just Ran a Real Drug Discovery Experiment. The Results Are Worth Paying Attention To. I have watched a lot of “AI does science” demos come and go. Most of them are carefully staged. A model generates something plausible-looking, a human expert nods approvingly, and the press release writes itself. What OpenAI published this week…
NotebookLM Just Got Agentic. Pay Attention. Google dropped a meaningful update to NotebookLM this week and the AI discourse barely flinched. Everyone was busy watching Anthropic’s policy announcements and xAI’s plugin marketplace rollout. Fair enough, those are real stories. But I think the NotebookLM upgrade deserves a harder look, because it changes what the tool…
A complete guide to building and hosting a remote MCP server in Python: Streamable HTTP with FastMCP, deployed to Heroku with gunicorn, secured with an API key or OAuth 2.1, and connected from Claude.ai and Cursor. Includes a real keyless weather API integration.
A practical, step-by-step guide to building a Model Context Protocol (MCP) server in Python with the official SDK and FastMCP, covering a hello-world tool and a structured weather tool with typed inputs and outputs.
xAI Just Shipped Something Developers Should Actually Pay Attention To The Grok Build Plugin Marketplace launched in beta this week, and I think it’s one of the more interesting developer moves in the current AI tooling race. Not because of the name, not because of the hype, but because of what the integration list actually…
The Blind Spot in AI Safety Nobody Is Talking About Most AI safety work is built around a single premise: one model, one user, one context. Evaluate it. Red-team it. Deploy it carefully. That mental model made sense when AI was a chatbot answering questions. It does not make sense anymore. Google DeepMind, together with…
The US Government Just Cut Anthropic Employees Off From Their Own Models Read that sentence a few times. Let it land. The US government has issued an export control directive suspending all access to Anthropic’s Fable 5 and Mythos 5 by any foreign national, whether they’re inside the United States or not. That includes foreign…
Claude Corps Is What “AI for Good” Should Have Always Looked Like Most AI lab philanthropy follows the same script. Announce a fund. Hold a competition. Award grants to a handful of well-connected nonprofits. Put out a press release. Move on. The organizations that actually needed help never had the grant-writing bandwidth to compete, and…
Claude Fable 5 Is the Real Deal. Here’s Why I’m Not Dismissing It. Most “new model drop” posts are just benchmark tables with enthusiasm sprinkled on top. I’ve written skeptically about that pattern before. But when Andrej Karpathy drops a 24,900-like tweet calling something a “major-version-bump-deserving step change forward,” I pay attention. Not because he’s…
DiffusionGemma and the End of Left-to-Right Thinking Google DeepMind dropped something this week that I think is getting undersold in the noise of the usual model release cycle. DiffusionGemma is an open experimental model, and the architecture underneath it is genuinely different from everything else currently in production. Not different in a marketing sense. Different…
