OpenAI Rewrites Safety Framework as Largest Training Run Stays Paused (2 minute read)
OpenAI is rewriting its Preparedness Framework while expanding monitoring, strengthening research-environment isolation, and moving alignment work earlier in model training. It has resumed many smaller or lower-risk workloads after a pause of little more than two weeks, but the largest planned frontier reinforcement-learning run and significant Astra and cyber workloads remain paused. Astra is an unreleased model that may reach OpenAI's Critical cyber threshold. OpenAI has not released the promised technical postmortem of the Hugging Face breach or the evidence behind Astra's possible Critical classification.
States Seek $200 Billion From Meta Over Child Social Media Addiction Claims (7 minute read)
California, Colorado, Kentucky, and New Jersey have accused Meta of harming children with technology designed to be addictive. The states claim Meta fueled a national youth mental health crisis and deceived users by promoting its apps as safe. They have filed a lawsuit charging the company with violating federal child privacy laws and state consumer protection laws. Meta plans to argue that it put in safeguards to protect young users and that it was truthful to consumers. The states are seeking damages approaching $200 billion, nearly 14% of the entire stock value of the company.

GenBio Launches a βVirtual Cellβ AI Model (7 minute read)
GenBio has announced a world model of a cell that can simulate both its natural state and responses to successive perturbations. AIDO Cell currently supports K562 and HepG2, two of the most widely used immortalized human cell lines in biomedical research. GenBio is preparing to launch an early-access academic collaborator program for scientists across academia, biotech, and pharma. AIDO Cell and similar systems could eventually become powerful tools for basic biological research, allowing scientists to perturb genes, proteins, or pathways, follow the predicted consequences across biological levels, generate hypotheses, and identify relationships that might take much longer to uncover in the lab.
China's Private Rocket Maker Just Landed a Booster Like SpaceX's Falcon-9--Here's How They Did It (34 minute read)
China's LandSpace recovered the first-stage booster of its ZQ-3 rocket on its second attempt. The ZQ-3 is comparable to SpaceX's current workhorse, the Falcon 9. It has a stainless steel rocket body and liquid oxygen-methane engines, which could enable it to achieve even lower launch costs than the Falcon 9. Its landing-leg recovery method allows the rocket to be quickly refurbished and relaunched as engineers only need to maintain the rocket itself without having to repair ground recovery equipment.

The vendors your buyers recognize are the ones already on their radar (Sponsor)
By the time a technical buying decision reaches procurement, the shortlist is already decided. The vendors on that list are not the ones with the best pitch but the ones the decision makers already recognize. TLDR reaches CTOs, engineering leaders, product managers, and founders while they evaluate tools and platforms for their work. 8 million read TLDR daily to stay informed about what shipped in their space.

Git at any scale (27 minute read)
A distributed version control system means that all instances of a repository are identical. There are many hard scalability and reliability challenges that make this quite difficult. Git compresses and stores code and metadata into packfiles, a simple binary serialization format that isn't ideal for managing at scale on a server. These large binary files must exist on a file system for Git to access them. The three main approaches to running repositories on many disks and many machines are to distribute the filesystem, distribute the packfiles, or distribute Git itself.
Mojoπ₯ is now open source! (4 minute read)
The Mojo language is now fully open source under the Apache 2.0 license with LLVM exceptions. Mojo is a novel general-purpose programming language that integrates the latest in compiler and programming research to unlock GPUs, AI accelerators, and other advanced compute. Users can now build their own compilers, but a prebuilt Mojo compiler is still necessary for customized MAX kernels or models.
OpenAI's Second-Quarter Sales Show Tepid Growth Compared With Anthropic (3 minute read)
OpenAI's revenue grew by 18% while its losses deepened from the first to the second quarter. Anthropic more than doubled its revenue in the same period, marking the first time its sales surpassed its older rival. It also swung to a small operating profit. The two companies' diverging fortunes show just how drastically the AI race has shifted since the beginning of the year.
Rethinking the Data Moat (9 minute read)
Raw data from the internet is unlikely to be the best data distribution for AGI. Not all tokens are created equal. The scaling law can be improved by equalizing intelligence per token. Better quality tokens maximize the efficiency of compute.

SpaceX's engineers have reams of data from all 13 Starship test flights, but there's no match for inspecting hardware after returning from space.
Extensible Software in the age of LLMs (32 minute read)
Platforms are hard to design, run, and debug, and exposing APIs to customers means a lot of upfront thought and long-term support, but it's worth it both for users and the creator.
