A recent analysis of the Muse Spark Open 816B model, released by Meta in October 2026, reveals that the actual hardware requirements for running it locally are significantly lower than initially advertised. While the model's page suggests a minimum of 700 GB of memory for the NVFP4 version, community-compressed GGUF files reduce this substantially. The smallest GGUF variant, IQ1_S, requires approximately 175.6 GB for model weights alone. However, the analysis also highlights that the cache memory, crucial for long contexts, can consume an additional 266 GB for a 1M token context, making the advertised 1M context window practically feasible only on systems with hundreds of gigabytes of memory.
