Wordgard – new rich-text editor by the creator of ProseMirror
Marijn Haverbeke, creator of ProseMirror, introduces Wordgard, a new rich-text editor currently at version 0.1. The editor aims to provide a simpler, more opinionated alternative while still offering powerful editing capabilities and extensibility.
Background
Marijn Haverbeke is the creator of ProseMirror, a popular JavaScript framework for building rich-text editors (think: Notion, Google Docs-style editing in the browser). ProseMirror is widely used in the tech industry but is known for being complex and low-level, requiring significant developer effort. Wordgard is Haverbeke's new editor project — it aims to be a higher-level, simpler-to-use product built on top of ProseMirror concepts. This matters because rich-text editing in the browser is notoriously difficult (historically, contenteditable HTML is buggy), and Haverbeke is one of the field's leading experts. The initial 0.1 release signals an early-stage preview, not a finished product. Developers watching this space will be interested in whether Wordgard succeeds in making ProseMirror's power more accessible without sacrificing quality.
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.
