DeepSeek-V4 Flash beats GLM-4.5-Air in laptop LLM showdown

A head-to-head comparison on a MacBook Pro M5 Max demonstrated that the 284 billion parameter DeepSeek-V4 Flash model, quantized to 2-bit, outperformed the 106 billion parameter GLM-4.5-Air model, which was quantized to 6-bit. Despite assumptions that higher precision would yield better results, DeepSeek-V4 Flash was faster and correctly solved a reasoning riddle where GLM-4.5-Air faltered. Both models performed equally on coding tasks, creative writing, and a common trick question, suggesting that for local, offline use on high-memory machines, model size can be more impactful than precision. AI

IMPACT Demonstrates that highly quantized large models can be run effectively on local hardware, increasing accessibility for AI operators.
