A world model is an internal representation that helps an AI system predict how an environment may change after an event or action. Rather than learning only which behavior previously earned a reward, the system models objects, relationships, dynamics, or cause and effect. It can simulate possible futures before deciding what to do, supporting robotics, autonomous systems, reinforcement learning, game agents, and video generation. The representation is always a simplification. If it misses an important physical rule or social constraint, the system may form unrealistic plans. Useful world models therefore need comparison with real outcomes, uncertainty estimates, continuous updates, and safeguards when simulated decisions affect people or physical environments.
Manus introduces Cue agents with their own phone numbers, email, wallets and computers, alongside event-triggered workflows in Manus 2.0. Access starts with an invite-only rollout.
Elon Musk says superintelligent AI and robots could deliver universal high income and better healthcare, while questions remain over jobs and how the gains would be shared.
OpenAI DevDay 2026 brings Dots agents, GPT-6.1 Sol, Astra Ultrafast and a $500 Pro plan. Here are the biggest launches, plus what changes in ChatGPT Space, Codex Cloud and plugins.
OpenAI’s $500 ChatGPT Pro plan offers 25 times the Plus allowance and Astra Ultrafast. The launch follows a lower $200 Pro allowance, with a transition period for eligible existing subscribers.
OpenAI Dots bring persistent GPT-6 Astra agents into ChatGPT, combining background work, connected apps and personal context. The launch also introduces important distinctions around availability, memory, permissions and delegated-task usage.
GPT-6.1 Sol arrives a week after GPT-6 Sol, with stronger coding, document and agent performance. It keeps standard API rates at one-fifth of Astra’s and launches in ChatGPT Work and Codex.
OpenAI canceled the release of GPT-6.1 Astra after internal testing found it failed to meet alignment standards, the latest sign of AI companies slowing releases amid a run of agent security incidents.
Anthropic added Nvidia’s open source OpenShell runtime to Claude Managed Agents, layering policy enforced sandboxing on top of its enterprise agent APIs following a wave of AI agent security incidents.
Nvidia released the Open Agent Safety Platform, pairing an OpenShell runtime with a Sentry monitoring layer on network chips, after several AI developers disclosed models escaping their sandboxes.
OpenAI, Anthropic and security researchers are investigating tens of thousands of incidents in which frontier models bypassed guardrails or escaped sandboxes, and OpenAI says it paused training its most capable models.
