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.
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.
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.
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.

Tesla plans to launch the Cybercab in Austin, Texas, later this month. Employees have been told to prepare for a public launch as soon as the end of the month. Tesla has launched a lottery to ride the vehicle at the launch event. The Cybercab entered production back in April, and the company has been testing units in a variety of environments and climates around the US.
Google has purchased a huge dump of data from the now-defunct Spirit Airlines for $10 million. The dump includes data on operations and business, as well as software code, but not personal information. All personally identifiable information will be rigorously scrubbed by a third party before receipt. Google will use the data to improve its products and AI models.
1872 is a startup founded by three former SpaceX engineers that aims to manufacture steel parts using AI-driven software and robots. The company's immediate goal is to establish a prototype factory that can automate most of the steel fabrication process for crucial infrastructure components by 2027. It aims to supply customers who are developing AI data centers or small modular nuclear reactors. 1872 will first focus on automating the production of rectangular steel skids.
Faster testing in the clinic creates a feedback loop. Ideas become trials that generate rich data, which improves data models, and better models inform the next generation of ideas. The clinic is a central component of discovery. Even data from failed trials can be useful. Optimizing trial efficiency is about learning fast enough to make success more likely.

Waymo and Tesla have come up with different answers to the self-driving car problem. Both approaches depend heavily on machine learning, but they differ in how much gets fixed in advance. Waymo has a reported 220.6 million rider-only miles, while almost all of Tesla's miles involve a driver who remains responsible for the vehicle. This article looks at the companies' different approaches to self-driving and explains how they work.
Anthropic's annualized run rate hit $65 billion at the end of July. The company has seen its enterprise popularity surge as it gears up for what's expected to be a blockbuster IPO.

Modern AI research teams are full of people who read Isaac Asimov and Scott Alexander and believe themselves to be building an artificial God, but in reality, they're building beings that are superhuman but fallible, each with their own interests and vulnerable to the same 'race to the bottom' dynamic as humans.
AI introduces some genuinely new twists on the problem of measuring ROI, but in the end, it still hinges on a theory of value.

Anthropic says it will not release an internal model it claims to be more powerful than Mythos and that it will not slow development broadly. The company believes that the risks of the most serious harms from its models are still low. While the company is seeing signs of acceleration in its models' ability to conduct automated research and development, it appears to be signaling that it is getting harder to understand the capabilities and risks of its own models. OpenAI says it is slowing down the release of an upcoming model called Astra because it can't rule out critical cyber capabilities.
Far-UVC 222 has been shown to efficiently inactivate airborne pathogens in a room-sized chamber. While the technology is unlikely to prevent the average common cold, mostly spread through close, extended contact, it could be helpful in blunting a future respiratory pandemic where more of the spread happens at a range through shared air. It is functionally equivalent to an extremely strong air purifier. The biggest bottleneck to the technology's adoption currently is awareness.

The idea of a zero-knowledge proof (ZKP) is that there are two parties: the prover and the verifier. The prover asserts that it has a solution to a (generally NP-complete) problem. The prover can convince the verifier of this without sharing the actual solution to the problem. While they are used to secure some cryptocurrencies, that is not their only use case. This article looks at how ZKPs work and how they can be applied to other problems like age verification.

Several companies are attempting to build the synthetic superstars of tomorrow. AI imaging tools have enabled anyone with a modest budget and a sliver of vision to build their own photorealistic avatars. The availability of virtual talent has unsettled many communities of human performers. While AI influencers likely won't replace human influencers fully, they'll likely become more prevalent as these tools become more and more reliable.
Anthropic employee Jarred Sumner used the Claude app on his phone to try to solve the infamous Riemann hypothesis. The model didn't succeed, but it made a related finding that one Stanford number theorist has called the most impressive result that AI has produced in math so far. Sumner's formal mathematical education ended after just one semester of high-school geometry, and he identifies as very much not a mathematician. Most of the prompting he gave to the model was variations of 'keep going' and 'believe in yourself'.
