Meta and Gemini 4 Face Off, Open-Source Camp Advances in Force
This edition (2026-10-12 to 2026-10-18) centers on a dense wave of model releases. About 14 months after its founding, Meta Superintelligence Labs released Muse Wonder and Muse Wonder Full, joining the frontier tier, and launched Muse Spark Open, an open-source multimodal MoE model with roughly 816B parameters; Google DeepMind rolled out Gemini 4 Argon worldwide, claiming it surpasses GPT-6 Astra and flagship Claude models on coding, cybersecurity, and other benchmarks, and topped ARC-AGI-3 with 97.5%. The open-source side was equally active: Reflection's 501B MoE model Beam, NVIDIA Nemotron 3.5 Super VL, Liquid AI LFM2.5, Apertus 1.5, and Mistral's time-series model Timestral were released in succession. On the industry front, Anthropic's Q3 revenue reached $16.8 billion but quarter-over-quarter growth slowed from over 140% to about 45%, and its November IPO valuation expectations may be revised down; Character.AI filed for bankruptcy and sold some assets to Disney; China plans to tighten export controls on 23 key AI technologies; eight U.S. states sued OpenAI, alleging ChatGPT is unsafe for children. On hardware, NVIDIA RTX Spark laptops went on sale, and NVIDIA open-sourced the Vera Rubin rack design at the OCP Summit.
