OpenLanguage is an AI-powered iOS language tutoring app built entirely with SwiftUI and the MVVM architecture. It offers a customizable learning experience with AI-generated dialogues, pronunciation training, and difficulty adaptation using OpenAI's API and ElevenLabs for text-to-speech.
Background
- This is a "Show HN" post, meaning a developer is presenting their own project to the Hacker News community for feedback. Hacker News is a tech-news aggregation site run by Y Combinator, popular among engineers and startup founders.
- The project is an open-source (publicly available code) iOS app that uses AI to help users practice foreign languages. "Open" in the name signals it's free to inspect, modify, or self-host — unlike most AI language tutors which are proprietary.
- The app likely uses a large language model (LLM) — the same kind of AI behind ChatGPT — to act as a conversation partner, give corrections, or generate exercises. Running such AI locally on an iPhone is technically challenging, which is part of the novelty.
- Language-learning apps like Duolingo or Babbel are the commercial competitors; this project offers a free, privacy-focused alternative where user data stays on-device.
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.
