Reflection AI Raises $2B to Build Open-Source Frontier Models as U.S. Answer to DeepSeek

Reflection, founded by former Google DeepMind researchers, raised $2 billion at an $8 billion valuation to build open-source frontier AI models as an American alternative to Chinese labs like DeepSeek. The startup, backed by major investors including Nvidia and Sequoia, plans to release a frontier language model next year trained on tens of trillions of tokens using Mixture-of-Experts architecture. The company aims to serve enterprises and governments seeking sovereign AI solutions while releasing model weights publicly but keeping training infrastructure proprietary.

Hugging Face Co-founder Thomas Wolf to Discuss Open-Source AI Future at TechCrunch Disrupt 2025

Thomas Wolf, co-founder and chief science officer of Hugging Face, will speak at TechCrunch Disrupt 2025 about making AI research and models open and accessible. The session will focus on how open-source development, rather than closed labs and big tech budgets, can drive the next wave of AI breakthroughs. Wolf has been instrumental in launching key open-source AI tools like the Transformers library and the BigScience Workshop that produced the BLOOM language model.

Meta Considers Abandoning Open-Source AI Strategy for Closed Superintelligence Models

Meta's new Superintelligence Lab is reportedly discussing a pivot away from open-source AI models like the delayed Behemoth model toward closed-source development. This potential shift would mark a major philosophical change for Meta, which has championed open-source AI as a differentiator from competitors like OpenAI. The company faces pressure to monetize its massive AI investments while competing with rivals in the commercialization of AI technology.
