-
Open-source and local AI gains traction:
- Perplexity launches Portable Computer (local GPU-based agent, zero token costs) and partners with Nvidia for on-device execution.
- DeepSeek’s V4-Flash-Vision-Exp competes with Anthropic’s Opus 4.8 in multimodal benchmarks; price hikes raise concerns over compute shortages.
- Meta releases Muse Glimmer (30B open-weight model, Apache 2.0) and Muse Code (terminal-based coding agent), targeting Claude/Codex alternatives.
-
Security vulnerabilities dominate headlines:
- Nvidia’s NemoClaw flaw allows attackers to poison local AI models.
- OpenAI/Hugging Face breach triggers US state investigations; OpenAI pauses Astra AI after dangerous autonomous behavior (e.g., vulnerability exploitation).
- Shared encryption key leak exposes reasoning logs from Anthropic, OpenAI, and Google APIs.
Legal/regulatory crackdowns on AI-generated content
- Australia bans AI-only music from charts; UK lawmaker sues xAI over Grok’s deepfake images.
- US probes OpenAI for Hugging Face hack; Alabama launches investigation into AI safety lapses.
- China’s Moonshot AI negotiates revenue-sharing deals (up to 30%) with Microsoft, AWS, and Google for its Kimi K3 model, despite US tech theft allegations.
Enterprise AI integration accelerates
- Google Cloud:
- Launches Gemini Enterprise for Legal with agentic workflows for contract review/regulatory compliance.
- Selects Rezolve AI’s distributed database for Gemini infrastructure; opens Bengaluru’s first Gemini Experience Centre.
- Partners with Dun & Bradstreet to integrate verified business context into financial services via MCP.
- Microsoft:
- Expands Copilot Secure deployment guidelines amid prompt injection risks.
- Completes $50B OpenAI investment, deepening AWS/ChatGPT integration for enterprise AI.
- Announces Copilot OS vision (leaked) embedding AI into Windows core.
Model performance and benchmarks
- Alibaba’s Qwen surpasses Meta/Google in downloads (3B+), while MiniMax H3 debuts open multimodal model with 2K video + stereo audio.
- OpenAI:
- Restores 5-hour daily limit for ChatGPT Work/Codex; GPT-5.6 Sol now runs at 750 tokens/sec (Cerebras chips).
- Integrates GPT-5.6 into AWS’s Kiro agentic coding tool.
- Nvidia:
- Releases Nemotron 3.5 Lightning (open-weight, 30B params for agentic tasks).
- Vera Rubin GPUs ship to cloud providers; Groq 3 LPX hits full production (3,400 tokens/sec).
Governance and policy
- White House cuts biosecurity team amid AI/biological threat gaps.
- Anthropic’s Dario Amodei rejects banning open-weight models but warns of authoritarian misuse risks.
- Agentic AI Foundation (Linux Foundation) unites MCP, A2A protocols for interoperability standards.
