OpenAI shuts down Sora and indefinitely pauses ChatGPT adult mode in March purge

Anthropic is privately warning top government officials that its unreleased model "Mythos" makes large-scale cyberattacks significantly more likely in 2026. The model enables AI agents to operate autonomously with high sophistication to penetrate corporate, government and municipal systems. One official told Axios a large-scale attack could occur this year as employees unknowingly create security vulnerabilities through unsupervised agentic AI use.

Anthropic has launched a memory import feature for Claude that lets users transfer their stored preferences, personal details, and conversation context from other AI services like ChatGPT, Google Gemini, and Microsoft Copilot. The tool generates copy-paste instructions that extract all memories from a competing service and import them into Claude, eliminating the need to rebuild your AI profile from scratch.

Suno has released v5.5 of its AI music generation model, prioritizing user customization over quality improvements. The update includes Voices (voice cloning via user-uploaded recordings), Custom Models (style training on user music catalogs), and My Taste (preference learning), with voice and custom features limited to Pro and Premier subscribers.

Google has released an Agent Skill for the Gemini API that provides language models with current information about their own APIs, SDKs, and best practices. Testing across 117 coding tasks showed Gemini 3.1 Pro's success rate jumped from 28.2% to 96.6%, though older 2.5-series models showed minimal improvement.

NVIDIA released gpt-oss-puzzle-88B on March 26, 2026, a 88-billion parameter mixture-of-experts model optimized for inference efficiency on H100 hardware. Built using the Puzzle post-training neural architecture search framework, the model achieves 1.63× throughput improvement in long-context (64K/64K) scenarios and up to 2.82× improvement on single H100 GPUs compared to its parent gpt-oss-120B, while matching or exceeding accuracy across reasoning effort levels.

Researchers at Meta, University of British Columbia, and partner institutions have developed hyperagents—AI systems that optimize both their task performance and the mechanisms controlling their self-improvement. Unlike previous self-improvement approaches locked to coding tasks, DGM-Hyperagents (DGM-H) demonstrate significant gains across four domains and can transfer improvement strategies to entirely new tasks.

OpenAI is shutting down Sora in two phases: the web app and mobile application close April 26, 2026, followed by the API on September 24, 2026. Users must export their videos and images before the cutoff dates, as user data will be permanently deleted afterward. The discontinuation reflects OpenAI's strategic shift toward coding tools and enterprise products.

Kwaipilot released KAT-Coder-Pro V2, the latest model in its KAT-Coder series, on March 27, 2026. The model features a 256,000-token context window and is priced at $0.30 per million input tokens and $1.20 per million output tokens. It targets enterprise-grade software engineering with focus on multi-system coordination and web aesthetics generation.

Cohere has released Transcribe, a 2 billion parameter open-source automatic speech recognition model that the company claims tops the Hugging Face Open ASR Leaderboard with a 5.42% word error rate. The model supports 14 languages and is available under Apache 2.0 license, outperforming OpenAI's Whisper Large v3 and competing models on both accuracy and throughput metrics.

Meta's FAIR lab released TRIBE v2, an AI model that predicts human brain activity from images, audio, and text. Trained on over 1,000 hours of fMRI data from 720 subjects, the model maps predictions to 70,000 voxels and often matches group-average brain responses more accurately than individual brain scans.

Replit has released Agent 4, a major update that fundamentally restructures how product teams design, collaborate, and build. The release replaces Design Mode with an infinite Design Canvas, moves from fork-and-merge to shared real-time collaboration, and enables concurrent planning and execution.

Google has launched a memory import feature for Gemini that lets users transfer their chat history, memories, and preferences from competing AI services like ChatGPT and Claude. The feature works by exporting conversation data and personal context from your existing AI service, then importing it into Gemini to enable faster personalization.
