Simon Willison created a GitHub repository that uses AI-generated scripts and GitHub Actions to build a 66MB SQLite database from Mozilla's browser compatibility data, hosted with open CORS headers fo…
Anthropic engineer Thariq Shihipar published a post arguing that HTML outputs improve human-agent workflows over Markdown, releasing 20 self-contained HTML examples that drew 4.4 million views in 16 h…
Anthropic's Claude Code engineering lead Thariq Shihipar argues that HTML is increasingly better than Markdown for keeping humans engaged in agentic workflows, citing richer visualizations and interac…
Researchers Charles Ye, Jasmine Cui, and Dylan Hadfield-Menell found that large language models often ignore explicit role tags like <system> or <user> and instead infer roles from text tone, enabling…
Prompt injection remains the top vulnerability for large language models, according to OWASP's Top 10 for LLM Applications, because it is an architectural property of how LLMs process input rather tha…
Vanta's Staff Software Engineer Noam Rubin outlines the company's agent development principles, emphasizing betting on model intelligence, enabling composition for emergent behaviors, and building str…
Tom MacWright criticizes job applications built entirely with AI, arguing they reveal nothing about the person behind the polished surface. The author reflects on how true character is found in action…
Postman launched Passport, a secure API access system that replaces real API keys with cryptographic credential references bound to the holder, to prevent secret sprawl and leakage in the age of AI ag…
Simon Willison built a test harness combining OPFS and Pyodide to explore whether Datasette Lite can edit persistent SQLite files stored in the browser's Origin Private File System. The tool allows te…
Developer Simon Willison ported the Moebius 0.2B image inpainting model to run in a browser using WebGPU, bypassing the original requirement for PyTorch and NVIDIA CUDA. The project, completed with as…
Cloudflare launched 'Temporary Cloudflare Accounts for Agents' on June 19, 2026, allowing unauthenticated users to deploy Workers via wrangler deploy --temporary without signing up. The ephemeral depl…
The US government ordered Anthropic to suspend access to its Fable 5 and Mythos 5 AI models for all foreign nationals, citing national security concerns over a jailbreak method. Anthropic complied imm…
Datasette creator Simon Willison launched datasette-apps, a plugin that embeds sandboxed HTML/JS applications directly alongside SQLite databases, transforming the tool from a read-only data explorer …
Sean Lynch and a new paper argue that AI systems should separate authentication from conversation to prevent misuse of powerful tools. The author warns that hiding permission inside conversational int…
Vibe coding—prompting an AI agent and shipping unread output—introduces a measurable defect tax that makes it unsuitable for mission-critical systems, with 45% of AI-generated code containing security…
Amazon Bedrock AgentCore harness is now generally available, enabling developers to build production-grade AI agents in minutes with two API calls. The managed abstraction handles sandboxed compute, m…
Chinese lab Z.ai released GLM-5.2, a 753-billion-parameter open-weight Mixture-of-Experts model that tops the Artificial Analysis Intelligence Index at #1, but its 1.51 TB weight size makes local depl…
Developers are reporting 'skill rot' as AI coding assistants automate debugging and problem-solving, reducing hands-on practice. A METR study found developers believed AI made them 20% faster but were…
