[AINews] High Taste Testers Ep. 1
AINews covers Meta’s Muse Spark Open and Reflection Beam 1.0 alongside Gemini, Anthropic, and OpenAI updates.
Latent Space’s AINews roundup leads with Meta’s Muse Spark Open, an 816-billion-parameter mixture-of-experts model with 42 billion active parameters, multimodal input, a 1 million-token context, and open weights under a custom attribution license. Artificial Analysis scored it 39, 13 points above NVIDIA’s Nemotron 3.5 Super VL, while noting weak results on agentic evaluations. Reflection released Beam 1.0, a 501-billion-parameter Apache 2.0 MoE scoring 30, with BF16, FP8, and NVFP4 weights plus a safety report. The digest also covers Gemini 4 Argon’s 1 million-token outputs, Haiku 5.5’s sharp price cut, and smaller releases from StepFun, Tencent, and Datalab.
