A tensor is a mathematical container for numbers arranged across one or more dimensions. A scalar can be treated as a zero-dimensional tensor, a list as one-dimensional, a table as two-dimensional, and images or batches of data as higher-dimensional tensors. Deep learning frameworks use tensors to store model inputs, parameters, activations, and gradients while performing efficient operations on CPUs, GPUs, or specialized accelerators. A tensor’s shape, data type, device, and memory layout determine which operations are valid and how much computation is required. In some mathematical contexts the word has a stricter meaning, but in everyday machine learning it usually refers to a multidimensional numerical array.
Google released a major upgrade to its Gemini Deep Research agent, giving developers access to advanced autonomous research capabilities through the Interactions API. The company also introduced DeepSearchQA, a benchmark for evaluating multi-step web research agents.
Google introduced the Titans architecture and the MIRAS framework to enable AI models to handle massive contexts and update their internal memory while running, improving performance in long-sequence tasks.
OpenAI co-founder Ilya Sutskever says the era of scaling compute and data as the main driver of AI progress is ending, arguing that meaningful advances now depend on true scientific breakthroughs and solving AI’s poor generalization.
Voice AI startup Wispr has secured another $25M in funding as its Flow dictation app surges in enterprise adoption and user retention, bringing total capital raised to $81M.
Google has released Gemini 3, its most powerful AI model yet, offering advanced multimodal reasoning, coding capabilities, and agentic planning tools across multiple platforms.
Pinterest is turning to open source AI models to cut expenses and enhance its visual search and shopping tools, even as the company forecasts softer holiday revenue. CEO Bill Ready says the approach will support performance while keeping infrastructure costs in check.
Elon Musk has unveiled Grokipedia – an AI-driven encyclopedia built on Grok that aims to offer factual, bias-free knowledge as an alternative to Wikipedia.
Andrew Tulloch, co-founder of the $12 billion AI startup Thinking Machines Lab, has joined Meta after previously rejecting what reports described as a $1.5 billion offer — a figure Meta has since called ‘inaccurate and ridiculous.’
OpenAI has announced a strategic partnership with Broadcom to design and deploy 10 gigawatts of custom AI accelerators, expanding its hardware ecosystem beyond Nvidia and AMD.
Google has unveiled Gemini Enterprise, a next-generation AI platform designed for business productivity and collaboration, positioning itself directly against Microsoft’s Copilot and OpenAI’s enterprise solutions in the race for workplace AI dominance.
