✦AI Summary
A technical experiment demonstrates how to optimize the Qwen3.8-27B AI model for local inference on consumer-grade hardware. The author achieves significant throughput gains by balancing model precision, speculative decoding, and memory management.
I gave Qwen3.8's MTP drafter another 69.2 MiB of precision. Throughput fell from 50.44 to 37.02 tokens per second. That result sums up the whole experiment: the best local inference setup is rarely made from the individually "best" parts.
