Cisco is in advanced talks to acquire Astrix Security, a Tel Aviv based startup specializing in monitoring and securing AI agents for between $250 million and $350 million, according to people familiar with the matter. Astrix has built technology designed to track what AI agents are doing, what data they are accessing, and whether their behavior falls within expected and authorized parameters, capabilities that are becoming increasingly critical as enterprises deploy autonomo

Cerebras Systems, the AI chip startup that built the world's largest single silicon die processor, went public on May 14 in one of the most closely watched technology IPOs of the year, raising $5.55 billion at a market capitalization of $95 billion and gaining 68% on its first day of trading under the ticker CBRS on Nasdaq. The debut added momentum to a wave of AI-related public listings that has now culminated in SpaceX's record-breaking IPO and is setting the stage for Anth

Google DeepMind released a new experimental AI model this week called DiffusionGemma, built specifically for high speed text generation using a diffusion-based approach rather than the standard autoregressive architecture that powers most large language models. While traditional LLMs generate text one token at a time in sequence, diffusion models can generate entire spans of text simultaneously, potentially enabling dramatically faster output for certain use cases. Google Dee

Robotaxi services have quietly moved from high profile prototype to genuine urban infrastructure in 2026, with autonomous ride hailing vehicles now operating commercially in dozens of cities across the United States, according to a new assessment from Nvidia's newsroom. The shift is one of the most tangible expressions of how quickly physical AI, the application of AI to real world mechanical tasks, has moved from lab to street. Passengers are routinely getting into vehicles

NVIDIA is reportedly developing a new AI model for healthcare documentation in partnership with Abridge, a startup that has become one of the fastest-growing names in clinical AI by helping doctors automatically generate notes from patient conversations. The collaboration would combine Nvidia's AI infrastructure and model-development expertise with Abridge's clinical workflow integrations, which are already used by a number of major US health systems to reduce the administrat

SpaceX made history on Friday with the largest initial public offering ever recorded, pricing shares at $135 and watching them rocket more than 19% on their first day of trading on the Nasdaq under the ticker SPCX.

AI company Anthropic announced late Friday that it has disabled access to its two most advanced models, Fable 5 and Mythos 5, after receiving a government directive citing national security concerns. In a blog post, the company said it received a letter from the US government at 5:21 p.m. ET on Friday instructing it to suspend access to both models for any foreign national, whether located inside or outside the United States, including the company's own foreign-national emplo
