Show HN: We post-trained a model that pen tests instead of refusing https://ift.tt/7rCXSAJ

Show HN: We post-trained a model that pen tests instead of refusing Anthropic and OpenAI's publicly available models are explicitly guard-railed so that they refuse offensive tasks. And their cyber-focussed models are gated for enterprises. This leaves SMEs and mid market open to major vulnerabilities. AI can be used as both an adversarial and defensive tool in the world of cyber. A worst case outcome is if only the adversaries have access. Meanwhile, most existing AI cyber tools are just wrappers. The problem is that they still have all the guardrails on from the foundation model where they will inherit its refusals. For this project we've post-trained a specific model on a decade of capture-the-flag contests. This won't be made available to anyone and everyone, but we do believe that responsible SMEs and midmarket companies also need access to these tools in order to identify key vulnerabilities in their systems; not just enterprises. We have developed two modes that run ...

Show HN: Cody – Voice control for Neovim using its own commands, LSP hey HN! This is Cody, I used GPT Realtime and gave it access to nvim and its native tools so you can literally talk instead of writing nvim commands. It's a prototype still, but the experience is really interesting. This is what I imagine using the soon-to-release Thinking Machines API. Let me know what you think :) https://ift.tt/Lp5US7G June 21, 2026 at 01:08AM

Show HN: Pagecast – Publish Markdown/HTML Reports to Cloudflare Pages https://ift.tt/10Pn89F

Show HN: Pagecast – Publish Markdown/HTML Reports to Cloudflare Pages I built this because I kept generating HTML/Markdown reports from Claude Code/Codex and needed a permanent share link instead of a localhost tunnel. Pagecast is a local CLI that publishes those files to your own Cloudflare Pages account. It supports Markdown and HTML, stable URLs, renaming, republishing to the same URL, and watch mode for continuous updates to same file. It is MIT licensed. The main design choice is that there is no hosted Pagecast account. It uses your Cloudflare account and deploys there directly and has claude code and codex integrations as skill/hooks. Basically it can be used as a replacement for codex sites or claude artifacts https://ift.tt/YAykeSt June 19, 2026 at 02:42AM

Show HN: Metiq: a real time 3D globe for 100 public datasets https://ift.tt/NfkL4il

Show HN: Metiq: a real time 3D globe for 100 public datasets The concept for metiq.space came after playing Global Magnates with friends and realizing how fragmented live global data is. ships, aircraft, satellites, ports, weather, hazards, infrastructure, cyber, and public datasets all exist, but they usually live in separate tools and maps. The goal was to build one interactive 3D globe where live public data could be visualized by latitude, longitude, and altitude. Surface data stays on the globe, while aircraft, satellites, and other above surface things can be represented in actual 3D space instead of being flattened onto a map. The outcome is an interactive globe that showcases Earth, air, sea, space, cyber, defense, infrastructure, politics, and the list is continuously growing. Majority of development right now is going into data filtering and deduping. https://metiq.space June 16, 2026 at 09:43PM

Show HN: Run Agent Skills with mistral.rs v0.8.10: /v1/skills support and more https://ift.tt/9UHPVQm

Show HN: Run Agent Skills with mistral.rs v0.8.10: /v1/skills support and more Hey all! I'm the maintainer of mistral.rs. I just landed support for OpenAI-compatible Agent Skills via a /v1/skills endpoint, and it works with local open models. Until now Skills have basically been locked to closed models, and with the ability to have private, local intelligence becoming increasingly important, but this feature allows you to do XYZ with local models. It's fully compatible with OpenAI's /v1/skills API, so you can drop mistral.rs into your existing code with minimal difficulty. We support the accompanying tools too: /v1/files or input_file for attaching files to your prompts, and mistral.rs also allows models to send generated files back using the OpenAI-compatible method. It's also easier than ever to try mistral.rs: we are including prebuilt binaries for NVIDIA CUDA, Apple Silicon, and CPU! # Linux/Mac > curl --proto '=https' --tlsv1.2 -sSf https://ift.tt/tgmd...
