1. Muse Spark Open Released as Most Capable US Open-Weight Model

Muse Spark Open is a new 816B-parameter open-weight model with 42B active parameters and a 1M-token context window, targeting coding, agentic work, and multi-step reasoning with text, image, video, and audio support. Its release raises the bar for US open-weight systems and puts pressure on proprietary labs by making large multimodal agents more deployable in local and private environments. It also ships custom Helion GPU kernels plus optimizations across major inference engines and hardware. Source-reddit

2. NVIDIA Releases Nemotron 3.5 Super VL 120B A12B Model Family

NVIDIA has released the Nemotron 3.5 Super VL 120B A12B family, including base, NVFP4, BF16, and LiLiCorr speculative decoding variants. The large vision-language model is aimed at multimodal and local AI applications, continuing NVIDIA’s strategy of pairing hardware with optimized open checkpoints. The NVFP4 variant is especially relevant for practitioners deploying efficient inference on newer NVIDIA hardware. Source-reddit

3. Apertus 1.5 Extends Open Models to Multimodal Reasoning with 262K Context

Apertus 1.5 expands the fully open Apertus family from text to multimodal reasoning, adding image and audio understanding while quadrupling the context window to 262,144 tokens. The 8B model uses 4T extra tokens and the 70B uses 2T, highlighting public, documented open infrastructure as an alternative to dependence on a few providers. Long-context multimodal open models are increasingly important for document, audio, and agent workflows. Source-huggingface
