OpenAI Joins Growing Trend of Companies Developing Custom Chips to Compete with Nvidia

OpenAI has announced plans to develop its own custom inference chip, named Jalapeño, in collaboration with Broadcom. This move marks a significant shift as major companies like Google, Apple, and SpaceX are also creating their own chips to reduce dependency on Nvidia, which has long dominated the AI chip market. The aim is to achieve greater control and performance tailored to specific needs, akin to the improvements Apple experienced after moving away from Intel. The trend towards custom silicon is expected to reshape the industry, as discussed in the latest episode of TechCrunch's Equity podcast.

Tokyo Startup Sakana AI and Beijing's 360 Security Launch AI Alternatives to Anthropic's Export-Banned Models

Sakana AI, based in Tokyo, and Beijing's 360 Security have introduced AI tools designed as alternatives to Anthropic's suspended Mythos and Fable models, following the U.S. government's export ban on these technologies. Sakana AI's product, Fugu, is an orchestration model that matches Fable 5 on key benchmarks by coordinating external models, while 360 Security unveiled Tulongfeng, a tool for automated vulnerability discovery. Both companies aim to capitalize on the market gap created by the ban, with Sakana's co-founder David Ha emphasizing the risks of relying on a single provider for national infrastructure. Meanwhile, 360 Security's founder Zhou Hongyi highlighted the strategic importance of vulnerability-finding AI amid concerns of uneven access to software examination capabilities. The launches underscore the growing competition in the AI space amid regulatory challenges.

Anthropic Accuses Alibaba of Largest Attack to Clone Claude Using 25,000 Fraudulent Accounts

Anthropic has accused Alibaba of orchestrating a significant campaign to clone its AI model, Claude, by utilizing nearly 25,000 fraudulent accounts to engage in over 28.8 million exchanges with the system. This allegation, detailed in a letter to U.S. Senators ahead of a Senate hearing on AI, highlights concerns about industrial-scale AI theft from U.S. companies. Anthropic claims that the attacks, which occurred between April 22 and June 5, targeted Claude’s advanced capabilities, including agentic reasoning and software engineering. The letter warns of a growing circumvention economy in China that enables such illicit activities, undermining U.S. investments in AI research and development. The situation escalates following past accusations against other Chinese firms using similar tactics to extract capabilities from American models. Alibaba has not yet responded to the claims.
