Anthropic’s Confidential Filing Reveals Customer Concentration By Cory Weinberg Source: Reuters Anthropic said nearly a quarter of its $4.6 billion in revenue last year came from just two customers, according to a confidentially filed IPO prospectus reported by Reuters on Monday. That’s one metric that could give investors pause ahead of its IPO, expected later this year. The report didn’t name the customers. The company also posted an eye-popping $42 billion net loss last year, although about $34 billion of that total stemmed from an accounting charge related to the increase in per-share value of outside funding it raised, which investors will likely overlook. The Information previously reported its net loss was about $15 billion in the first half of this year, with about $12 billion related to the same accounting charge. The company said in the risk factors portion of its prospectus that its business was “resource-intensive” that requires a “continuous and overlapping cadence” of model releases. It also said the models it worked on could be dangerous. “Our development of highly advanced models, platforms, and applications and expansion of use cases could further increase the risk that our models cause harm,” Anthropic said in the filing. 2. OpenAI Will Not Ship GPT-6.1 Astra Due to Safety Concerns By Rocket Drew Source: The Information OpenAI has decided not to release the AI model that it had intended to release as GPT-6.1 Astra due to its results on safety tests, a spokesperson said Monday. The model performed worse than GPT-6 Astra—OpenAI’s newest model, released earlier this month—on tests measuring whether it pursues users’ goals and is transparent with users about its actions. “For anything regarding safety and alignment, there’s a trade off. You really do need to find what’s the right line between staying within scope, but also avoiding laziness in terms of how the model actually pursues tasks even when it hits friction,” said Saachi Jain, OpenAI’s head of safety systems, in a statement. While the model was less lazy than its predecessors, “it didn’t quite meet the bar in terms of staying within scope and authorization, and how it communicates back to the user about the type of work it’s done.” Along with Jain, OpenAI Vice President of Research Mia Glaese recommended to research leadership, including chief scientist Jakub Pachocki, that the model not be released, according to the spokesperson. The decision follows a string of incidents in which OpenAI’s models engaged in cyberattacks or other unwanted activity. Those incidents have drawn regulatory scrutiny, fueled calls for a slowdown in frontier AI development and prompted OpenAI to pause training of its most capable new models. The Wall Street Journal first reported on OpenAI’s decision about GPT-6.1. 3. Nvidia Authorizes $150 Billion Stock Buyback Increase, Largest In History By Phoebe Liu Source: The Information Nvidia’s board approved adding $150 billion to its stock repurchase program, bringing the total amount currently authorized to $235 billion.
