CPU LLM Optimization: Active Parameters Key to Speed

A Reddit user is exploring a novel approach to running large language models on CPUs without GPUs, aiming for a decode speed of 100 tokens per second for a 10 billion parameter model. The core idea is that CPU decode speed is determined by active parameters per token, not the total, suggesting that architectures with granular Mixture-of-Experts (MoE) and ternary weights could scale model capacity without sacrificing speed. Initial tests on a smaller model showed a significant increase in tokens per second when optimizing for active parameters. AI

IMPACT This approach could enable running larger language models on consumer-grade hardware, broadening accessibility for AI development and deployment.

RANK_REASON The item discusses a technical approach to optimizing LLM performance on specific hardware (CPUs), rather than a new model release or significant industry event.

    The idea: on a CPU the decode speed depends on the active params per token, not the total. My objective is trying to run a 10B at 100tok/s on a mid level PC (No GPU).
