They measure token usage by tracking the number of tokens processed and billed for a given task, since token efficiency is defined as the amount of data processed and billed. To compare providers in practice, run the same tasks on OpenAI, Meta, SpaceXAI, and Anthropic and compare the tokens consumed per task and resulting cost, with fewer tokens for the same output indicating better token efficiency.

Samsung says zHBM enhances energy efficiency threefold compared with HBM5 and reduces thermal resistance by more than half. It also cuts the distance data must travel by stacking memory above the AI accelerator, yielding higher bandwidth and better power efficiency. Answered

Token-efficiency improvements mean models like GPT-5.6 and Grok 4.5 complete the same tasks while consuming fewer tokens, and token usage is the metric that gets processed and billed. Using fewer billed tokens per request directly reduces per-request cost, and those savings compound at enterprise scale where many requests make token reductions translate into significant cost reductions.

Buyers should expect lower operational costs and big savings at scale from a more token-efficient model, but those savings may come with reduced raw performance or capabilities compared with a higher-power model like Anthropic’s Fable 5. The article says enterprises are increasingly trading some model power for token efficiency to cut AI spending. Answered
