MacBook's quantized DeepSeek-V4-Flash nearly matches DGX Spark performance

A comparison of DeepSeek-V4-Flash performance revealed that a heavily quantized version running on a single MacBook achieved a 54% success rate on the Terminal-Bench 2.1 benchmark. This performance was remarkably close to a more powerful setup using two DGX Spark machines with a native mixed FP8/FP4 checkpoint and speculative decoding, which scored 52%. While not a controlled study of quantization alone, the results suggest that aggressive quantization can yield competitive performance even against high-end hardware. AI

IMPACT Suggests aggressive quantization can yield competitive performance, potentially lowering hardware barriers for advanced model deployment.
