Nanbeige4.3-33B model performance compared across three inference engines on MacBook Pro M5 Max

A user on Reddit compared the performance of the Nanbeige4.3-33B model across three different inference engines on a MacBook Pro M5 Max. The comparison focused on prefill and decode speeds, time to first token, latency, and memory usage, with context lengths ranging from 512 to 32K tokens. The results indicated that the Nanbeige4.3-33B model is slow and inefficient with its KV cache, consuming a large amount of memory. Despite its coding capabilities, the user suggested sticking with Qwen models for better performance. AI
