BUSINESS
Funding & Investment
OpenAI Co-founder's Safe Superintelligence Valued at $32B
Financial Times via TechCrunch (2025-04-12)
Safe Superintelligence (SSI), led by former OpenAI chief scientist Ilya Sutskever, has reportedly raised an additional $2 billion in funding at a $32 billion valuation, according to the Financial Times. This follows an initial $1 billion raise, with reports suggesting another $1 billion round was already in the works.
M&A
xAI Acquires X in All-Stock Deal
Elon Musk has announced that his AI startup xAI has acquired his social media company X (formerly Twitter) in an all-stock deal. The merger makes strategic sense as xAI's chatbot Grok was already deeply integrated with X, which has been facing financial challenges. The acquisition provides Musk with a way to consolidate his tech empire while giving his AI venture direct access to X's user data and distribution platform.
Company Updates
OpenAI May Require ID Verification for Advanced API Access
OpenAI appears to be implementing stricter access controls for its most advanced AI models. According to a support page published last week, the company may soon require organizations to complete an ID verification process called "Verified Organization" to access certain future AI models through its API. This move likely reflects growing concerns about AI safety and misuse as model capabilities increase.
ByteDance Releases New Reasoning AI Model
TikTok parent company ByteDance has entered the reasoning AI competition with its new model, Seed-Thinking-v1.5. The model reportedly achieved an 8.0% higher win rate over DeepSeek R1, demonstrating strength beyond just logic or math-heavy challenges. This release positions ByteDance as a significant competitor in the advanced reasoning AI space alongside models from OpenAI, Google, and other major players.
Meta's Vanilla Maverick Model Underperforms on Popular Benchmark
Meta has faced criticism after using an experimental, unreleased version of its Llama 4 Maverick model to achieve a high score on the LM Arena benchmark. Following the controversy, benchmark maintainers changed their policies and rescored the unmodified, vanilla Maverick model, which subsequently ranked below rivals. This incident highlights ongoing tensions in AI benchmarking and transparent reporting of model capabilities.
Market Analysis
Trump Backs Off on Electronics Tariffs
In a move that could bring relief to the tech industry, former President Trump has reportedly backed off on planned electronics tariffs. According to VentureBeat, the decision came in response to "continuing stock market woes and perhaps tech industry lobbying." This policy reversal may benefit AI hardware manufacturers and chip companies that rely on global supply chains.
