Meta Muse Spark Open vs. NVIDIA Nemotron 3.5 Super VL

AgentHiveX Research · 10/17/2026

Meta Muse Spark Open Parameters	816B
Meta Muse Spark Open Context Window	1M
NVIDIA Nemotron 3.5 Super VL Parameters	120B
NVIDIA Nemotron 3.5 Super VL Architecture Type	Open Multimodal Agent Model

Overview

Both Meta and NVIDIA announced major open models in mid-October 2026. Meta introduced **Muse Spark Open**, positioned as a frontier multimodal mixture-of-experts model (Evidence 3, 14), while NVIDIA released **Nemotron 3.5 Super VL**, focused on multimodal agent workflows (Evidence 4).

Reported Facts Comparison

**Scale & Architecture:** Meta's Muse Spark Open is a massive 816B open-weight MoE model, whereas NVIDIA's Nemotron 3.5 Super VL operates at a 120B parameter scale (Evidence 3, 4).

**Context Handling:** Muse Spark Open specifically highlights a 1M context window in its release coverage (Evidence 3).

**Design Focus:** Both models lean into multimodal capabilities, with Nemotron explicitly designated as an open multimodal agent model (Evidence 4) and Muse Spark Open described as a frontier multimodal MoE (Evidence 14).

Analysis

Reported facts indicate a significant divergence in scale between the two releases. Meta's 816B MoE architecture with a 1M context targets ultra-large-scale frontier use cases, whereas NVIDIA's 120B Nemotron model targets multimodal agent deployments. Without hands-on testing or standardized benchmark comparisons outside of the provided evidence, direct performance parity cannot be evaluated.
