News reporting focused on AI and machine learning, covering the companies behind these technologies, their real-world applications, and the ethical concerns they raise. This includes areas like generative AI (large language models, text-to-image and video), speech tech, and predictive analytics.
xAI's Grok 4.3 model is now generally available on Amazon Bedrock, offering configurable reasoning effort, tool calling, and a 1 million token context window. The model runs on the Mantle inference engine and supports OpenAI-compatible APIs for easy integration into agentic workflows.
NVIDIA released Nemotron 3 Embed, a collection of open embedding models led by an 8B model that ranks first overall on the RTEB leaderboard. The collection includes efficient 1B variants optimized for production-scale retrieval, agentic workflows, and Blackwell hardware. Enterprise partners including Automation Anywhere, Boomi, and Zoom are already evaluating the models for agent memory, code retrieval, and enterprise search.
Noma Labs discovered a critical prompt injection vulnerability in GitHub's new Agentic Workflows, dubbed GitLost. An unauthenticated attacker could leak private repository data by posting a crafted GitHub Issue in a public repository belonging to the same organization. The vulnerability exploits the AI agent's failure to distinguish trusted instructions from untrusted user content.
Generative AI is moving from flat-rate subscriptions to usage-based billing as agentic workflows consume far more tokens. The token price itself is splitting into segments by speed, specialization, and value. However, measuring costs precisely while benefits remain vague risks turning token usage into a misleading proxy for productivity.
NVIDIA has released Nemotron 3 Nano Omni, an open multimodal model that combines vision, audio, and language processing. It offers up to 9x higher throughput than other open omni models, topping leaderboards in document intelligence, video, and audio tasks. The model supports agentic workflows like computer use and is available now on multiple platforms.
GitHub has paused new sign-ups for Copilot Pro, Pro+, and Student plans while tightening usage limits and removing Opus models from Pro plans. These steps aim to maintain service reliability amid rising demands from agentic workflows. Existing users see usage displays in VS Code and Copilot CLI, with options to upgrade to Pro+ for over 5X higher limits or request refunds through May 20.
