Scaling Efficiency

Scaling efficiency is the model-development pressure in E246｜何谓蒸馏？聊聊硅谷如何看中国开放模型逼近前沿 where teams try to improve capability while lowering training and inference cost. [[WangTiezhen|王铁镇]] says Chinese open-model teams were shaped by compute scarcity, making architecture, data engineering, reinforcement learning, and serving optimization more central than a simple “more compute” story.

The source treats compute constraint as both a limitation and an innovation pressure. If a model team cannot rely on unlimited frontier GPUs, it may pursue attention variants, better utilization, model-infra co-design, and cheaper inference paths that make the resulting model more disruptive to closed API providers.

Key Claims

• Capability gains should be evaluated per unit of compute, cost, latency, and deployability, not only benchmark score.
• Compute scarcity can push teams toward architecture and inference optimization.
• Efficiency gains can make open models commercially disruptive even when closed frontier models remain stronger at the top end.
• [[KimiK3|Kimi K3]] is source-framed as an efficiency case as well as a capability case.

Connections

• AI Inference Cost Structure, Inference Acceleration Stack, and Token per Watt - cost and efficiency layers.
• Model-Infra Co-Design, Open Source AI Infrastructure, [[VLLM|vLLM]], Prefix Caching, and Continuous Batching - serving and architecture context.
• Domestic AI Chip Catch-Up, Compute Freedom / 算力自由, and AI Compute Continuity - hardware and compute-availability pressure.
• Model Distillation / 模型蒸馏, Kimi K3, DeepSeek, and Qwen - model-progress debate where efficiency should not be ignored.
