  • Microsoft shifting Copilot away from OpenAI and Anthropic models. Microsoft is replacing third-party frontier models in Copilot with its own MAI-1 to reduce costs. Early evaluations shared by Ethan Mollick suggest MAI-1 trails Claude Sonnet 4.6 on publicly available benchmarks. via THE DECODER
  • DeepSeek moves to build its own chips. Facing US export controls that have cut off access to advanced NVIDIA hardware, DeepSeek has begun designing its own AI chips, with founder Liang Wenfeng’s electronics engineering background cited as a factor behind the move. via Ars Technica – AI
  • China considers export curbs on its top AI models. China is reportedly weighing restrictions on exporting its most capable AI models, a development that would affect European partners and global developers relying on Chinese open-weight releases. via THE DECODER
  • Security researchers trick GitHub’s AI agent into leaking private repos. A technique called “GitLost” demonstrated that GitHub’s AI agent could be manipulated via prompt injection to exfiltrate content from private repositories during normal coding sessions. via Noma Security

Who shipped

OpenAI made the overnight’s biggest wave by announcing Sol (GPT-5.6) alongside Terra and Luna, expanding preview access globally ahead of Thursday’s public launch. Anthropic extended Claude Cowork to mobile and web, and separately published a new interpretability technique — the Jacobian Lens — that makes Claude’s internal reasoning visible to researchers. Meta shipped Muse Image and previewed Muse Video. xAI confirmed Grok 4.5 is moving from beta to public access. Google expanded Managed Agents in the Gemini API with background task execution and remote MCP support.

Open-source pulse

Cohere open-sourced Transcribe Arabic under Apache 2.0, claiming it as the most accurate open model for Arabic speech recognition. Liquid AI released Antidoom, a Final Token Preference Optimization method aimed at reducing reasoning loops in language models. Krea 2 crossed 200,000 downloads on Hugging Face shortly after its open release.

Money, infra & hardware

SambaNova closed a $1B Series F at an $11B valuation, just five months after its previous mega-round and after Intel was reported to have considered a $1.6B acquisition. NVIDIA announced the Vera CPU, marketed for agentic workloads requiring high single-threaded performance. US manufacturers reported rising energy costs tied to AI data center demand, via Ars Technica.
