New Apple compression algorithms: LZRAVEN and LZMESH
Apple has introduced two new compression algorithms, LZRAVEN and LZMESH, in its compression library. These algorithms are designed to improve data compression efficiency and performance for developers.
Background
Apple has open-sourced two new compression algorithms it developed: LZRAVEN (optimized for text, code, and data) and LZMESH (designed specifically for 3D geometry data used in games and graphics). These join Apple's earlier LZFSE algorithm and the industry-standard zlib. The release includes reference implementations on GitHub for developers to integrate into non-Apple platforms and applications. This is significant because compression directly affects download sizes, memory usage, and performance — particularly in games, where 3D mesh data can be a major bottleneck. Apple is contributing these as alternatives to existing open-source compressors, potentially offering better ratios or speed for specific use cases. Developers working on cross-platform or Apple-native software can now evaluate whether these algorithms improve their storage or transmission efficiency.
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.
