Big Tech's investment in artificial intelligence is surging, with companies like Alphabet, Amazon, and Meta projecting a combined capital expenditure of over $630 billion, a sum that rivals the economy of Sweden. This massive spending, primarily focused on scaling AI computing, is raising eyebrows among investors, according to a report from Fortune.
During recent earnings calls, tech giants revealed significant increases in their capital expenditure (capex) projections for 2026. Alphabet announced plans to double its capex to nearly $185 billion. Amazon intends to allocate $200 billion to capex, exceeding Wall Street expectations. Meta anticipates a full-year capex increase to $135 billion. Microsoft's growing projections also contribute to the staggering total. This concentrated investment strategy marks a shift, as companies are focusing their spending on a single purpose: scaling AI computing, rather than spreading it across a variety of strategic bets, according to Fortune.
Simultaneously, advancements in AI continue to emerge. Researchers from Stanford, Nvidia, and Together AI developed a new technique called Test-Time Training to Discover (TTT-Discover). This method optimizes GPU kernels, achieving speeds twice as fast as those achieved by human experts, as reported by VentureBeat. TTT-Discover allows models to continue training during the inference process, updating their weights for specific problems. This approach challenges the traditional "frozen" model paradigm, where parameters remain static during reasoning.
In other AI-related news, Google announced the public preview of the Developer Knowledge API and its associated Model Context Protocol (MCP) Server. This API aims to provide AI-powered developer tools with access to the most accurate and up-to-date documentation. As the ecosystem of AI-powered developer tools expands, ensuring these models have access to current information is critical, according to the Google Developers Blog.
Furthermore, the rise of AI-driven social platforms is evident. Moltbook, a Reddit-like platform for AI agents, quickly gained popularity, attracting over 1.7 million agent accounts. These agents have collectively published over 250,000 posts and generated more than 8.5 million upvotes, according to MIT Technology Review. The platform, launched by tech entrepreneur Matt Schlicht, allows instances of the open-source LLM-powered agent OpenClaw to interact.
These developments highlight the rapid evolution of AI, from infrastructure investments to novel optimization techniques and the emergence of AI-focused social platforms.
