Show HN: NodePad – AI agent on a canvas instead of a linear chat
NodePad is an AI agent interface that replaces a traditional linear chat with an interactive canvas, allowing users to arrange and manage AI interactions in a more flexible, visual workspace.
Background
- NodePad is a web-based tool that replaces the familiar linear chat interface (like ChatGPT) with a freeform "canvas" where an AI agent can place text, images, and UI elements anywhere on an infinite 2D surface.
- The key idea: instead of scrolling through a single thread of back-and-forth messages, users can arrange information spatially, resembling tools like Notion, Miro, or Apple's Freeform — but with an AI agent that actively generates and organizes content on the canvas.
- It was posted as a "Show HN" on Hacker News, meaning it was built by an independent developer or small team presenting their project to the tech community for feedback.
- This reflects a broader trend in 2024-2025 where AI tools experiment beyond simple chat interfaces — competitors include Anthropic's "Artifacts" (side-by-side code/preview) and Tldraw's "Make it Real" (drawing-to-code). The spatial canvas approach aims to solve chat's limitations: lost context in long conversations, inability to visually organize outputs, and poor support for multi-step creative workflows.
Max Weinbach says he had early access to OpenAI's new model GPT-5.6 Sol, calling it his favorite model by far. He highlights that it never gives up and will keep reasoning until it's done. OpenAI announced that GPT-5.6 Sol, along with Terra and Luna, will launch publicly on Thursday, with preview access expanding globally now.
The US government ordered Anthropic to suspend access to its Fable 5 and Mythos 5 models for all customers, citing a potential jailbreak technique that involved asking the model to review a codebase for vulnerabilities—a capability Anthropic says is available in other public models. Access was abruptly cut off on June 12.
Andrej Karpathy announces the release of Claude Fable 5, the same underlying model as Mythos but with added safeguards. He calls it a major step forward, particularly for long problem-solving sessions on difficult tasks, and describes it as state-of-the-art on nearly all benchmarks with exceptional performance in software engineering, research, and vision.
Roman Storm warns that the legal theory in his case could set a precedent making open-source developers liable for how others use their code, potentially criminalizing the mere publication of privacy, messaging, or crypto tools. He notes that developer Michael Lewellen cannot publish lawful code due to prosecution fears, and argues this chilling effect extends beyond any single case.
Meta's engineering culture is deteriorating under Mark Zuckerberg and Scale AI CEO Alexandr Wang, who have introduced keyboard tracking, reassignments to data labeling, and AI-centric performance metrics. Critics argue this incentivizes performative AI use, drives away experienced engineers, and contributed to a major Instagram hijacking incident caused by AI-written and AI-reviewed code.
