Mac Studio efficiently serves Qwen3.5-122B with optimized cold caching

By PulseAugur Editorial · [1 sources] ·

A developer has optimized the qMLX engine to efficiently serve multiple sessions of the Qwen3.5-122B model on a single Mac Studio with 96GB of RAM. By implementing a cold caching strategy that heavily relies on an on-disk KV cache, the system achieved a significant reduction in prefill compute, allowing for concurrent sessions with minimal GPU load. This optimization enables the use of local models for sub-agent functionalities. AI

IMPACT Optimizes local hardware usage for running large language models, potentially enabling more complex AI applications on consumer-grade machines.

RANK_REASON This is a technical optimization of existing models and software for local hardware, not a frontier release or significant industry event.
