OpenAI has improved prompt caching for GPT-6, delivering higher cache hit rates by default and offering developers discounts of up to 90% on cached input tokens reused within a minute window. New tools include a Prompt Caching Dashboard to track hit rates and a diagnostics tool to identify cache misses. Additional features include explicit cache breakpoints, cache prewarming, and the ability to adjust reasoning effort without breaking cache. GitHub Copilot reported a 50% reduction in fresh token processing using the system.

Rabbit has launched OS3, an agentic operating system designed to control multiple devices through a single chat interface. Users state a desired outcome and OS3 handles execution by reasoning with connected AI models, web services, and up to five linked devices simultaneously. Key features include multi-device orchestration, a continuous single conversation thread, universal skill compatibility via URL paste, and direct computer control using rabbit's DLAM technology. OS3 supports bring-your-own-key model flexibility and runs on Windows, Mac, Linux, cloud VMs, and the r1 hardware device.

President Trump announced at the United Nations that the United States is officially renaming Artificial Intelligence to Super Intelligence. Trump stated that all US government documents will be updated to use the new term and its abbreviation, SI. The declaration, made during a UN address, represents a significant branding shift in how the federal government formally refers to AI technology, though no technical or policy changes to AI programs were announced alongside the renaming.

Xiaomi has released and open-sourced MiMo-V2.6, a multimodal AI series including MiMo-V2.Pro, MiMo-V2.Flash, and MiMo-V2.Pro-UltraSpeed, which delivers up to 20x faster output. MiMo-V2.Pro scores 46.32 on the Artificial Analysis Intelligence Index, surpassing Kimi K3 and Qwen3.8 Max as the top open-source model. Training used reinforcement learning over 30 steps across roughly 750k trajectories, costing $2.62M for Pro, boosting DeepSWE v1.1 scores by about 14 points. API pricing remains unchanged from V2.5.

Meta's AI app Muse has outpaced ChatGPT's early mobile growth, recording 1.8 million iOS downloads in the U.S. and Canada in its first 12 days compared to ChatGPT's 1.3 million, according to Apptopia. Muse also reached 642,000 U.S. daily active users versus ChatGPT's 231,000 at the same stage. The app has 2.8 million total global installs and climbed to No. 1 on the U.S. App Store, with over 95% of its users also being Facebook users.

OpenAI is calling for the United States to lead the development of global technical standards for frontier AI, particularly to govern recursive self-improvement (RSI), where AI systems increasingly drive their own research and development. The proposal includes two pillars: coordinating national and international standards through existing AI safety institutes, and establishing common measurements and incident reporting protocols. OpenAI warns that without such standards, RSI could cause humans to lose practical control over AI development.

OpenAI is expanding OpenAI Academy with new role-based learning paths for developers, business leaders, educators, and college students. The four tracks are Apply AI at Work for knowledge workers, Build with AI for developers using Codex or the OpenAI API, Lead AI Adoption for strategy and change management leaders, and Teach and Learn with AI for educators and students. Courses use real tasks and include assessments that earn learners an OpenAI Academy badge. Organizations can integrate the paths into onboarding and executive programs.

xAI has launched Grok 4.7, its most capable model for coding and knowledge work, priced at $2 per million input tokens and $6 per million output tokens — half the cost of comparable rivals like GPT-5.6 Sol. Built on a larger base model with extended reinforcement learning, Grok 4.7 scores 46.3% on CursorBench 4.0 and leads on EEBench at 64.0%. It also tops LatchBio's biosafety benchmark at 62.4% and is available via Cursor, Grok Build, and the xAI API.
