OpenAI has introduced GPT‑5.1-Codex-Max, a new coding model available in its Codex developer environment. This model enhances AI-assisted software engineering with improved reasoning, efficiency, and interactive capabilities. It replaces GPT‑5.1-Codex as the default model, designed to handle complex software development tasks across multiple contexts.

Fetch AI, a startup led by Humayun Sheikh, has launched three interconnected products aimed at enhancing the ecosystem of AI agents. The new offerings include ASI:One, a personal-AI orchestration platform, Fetch Business, a verification and discovery portal for brand agents, and Agentverse, an open directory with over two million agents. This initiative seeks to establish a robust infrastructure for what Fetch describes as the 'Agentic Web.'

CraftStory, a new AI startup founded by the creators of OpenCV, has launched a video generation system capable of producing realistic human-centric videos up to five minutes long. This technology significantly outpaces competitors like OpenAI's Sora and Google's Veo, which have shorter duration limits. The startup has secured $2 million in funding to support its innovative approach to the AI video industry.

Elon Musk's AI startup xAI has launched Grok 4.1, a large language model designed to enhance user experience on Grok.com and the social network X. This new model features improvements such as faster reasoning, better emotional intelligence, and a significantly reduced hallucination rate. Currently, there is no API access available for developers. The launch comes as Google prepares to unveil its Gemini 3 model, which has been recognized as the most powerful large language model by independent evaluators.

Writer, a San Francisco-based AI startup, is launching a unified AI agent platform that allows employees to automate complex business workflows without coding. The platform, named Writer Agent, integrates chat-based assistance with autonomous task execution. Starting Tuesday, enterprise customers can use natural language to instruct the AI for tasks such as creating presentations and analyzing financial data, saving these workflows as reusable 'Playbooks' that run automatically.

Microsoft has introduced Fabric IQ, a new semantic intelligence layer integrated into its Fabric data platform, unveiled at the Microsoft Ignite conference. This technology aims to enhance the effectiveness of enterprise AI agents by ensuring that data not only reflects patterns but also aligns with actual business operations. Fabric IQ creates a shared semantic structure that maps datasets to real-world entities, their relationships, and operational contexts, marking a significant advancement in Microsoft's data platform strategy.

Microsoft is restructuring its Windows operating system to create what it calls the first 'agentic OS.' This new framework will embed the necessary infrastructure for autonomous AI agents to operate securely at enterprise scale. Announced at the Ignite conference, the integration of native agent infrastructure into Windows 11 will enable AI agents to perform complex tasks, discover tools, and interact with applications in secure environments, marking a significant evolution in personal computing.
