Nvidia-backed Reflection AI has launched Beam, a 501B-parameter open-weight AI model built for coding, reasoning and AI-agent workloads. Beam is aimed at competing with leading open-weight models from China. Beam is a text-only mixture-of-experts model with: • 501B total parameters, 23B active • 1M-token context window • Pretrained on 23.8T tokens • Built for coding, reasoning, tool use and agentic workloads Reflection says Beam performs comparably with Z .ai’s GLM-5.2 on advanced reasoning benchmarks while using 3-4x less inference compute. The company’s benchmark claims have not yet been independently verified. Beam’s reinforcement-learning run used 10,500 NVIDIA $NVDA GB300 GPUs for four…

TRUMP EXPECTED TO UNVEIL MAJOR SOUTH KOREAN U.S. ENERGY INVESTMENTS President Trump is expected to announce plans tied to South Korea’s $350B U.S. investment package, including about $54B for the Alaska LNG project and other infrastructure, according to Reuters. The broader package includes $150B already earmarked for shipbuilding and another $200B for strategic investments. Among the projects being discussed: • Up to 8 large nuclear reactors in the U.S., with 6 Westinghouse AP1000 units and 2 South Korean APR1400 reactors. At roughly $15B per reactor, nuclear could account for a large portion of the package. • A potential South Korean stake in Westinghouse, with discussions around a 5% to…
