Detailed Breakdown

Energy Consumption

LLaMA 3.1 8B is the most widely deployed open-source model, used as a base for thousands of fine-tunes. At ~0.3 Wh per query, it's efficient enough to run on a single consumer GPU. Its 128K context window at this size makes it uniquely versatile for self-hosting.

Power Source & Carbon

As an open-source model, energy impact depends entirely on deployment location. Popular cloud hosts include AWS, GCP, Azure, and specialised providers like Together AI and Fireworks. Meta's own data centres run approximately 60% on renewable energy.

Water Usage

At ~1.1 mL per query, LLaMA 3.1 8B's water footprint is minimal. Self-hosted on consumer hardware, water consumption drops to effectively zero.

About LLaMA 3.1 8B

LLaMA 3.1 8B is an open-source text and chat model from Meta, released in July 23, 2024, that runs well below the category average for energy consumption at 0.30 Wh per query. Because its weights are publicly available, it can be self-hosted on any infrastructure — meaning its carbon footprint depends entirely on where and how you choose to run it. At 8B parameters, it most popular small open-source model for fine-tuning and deployment.

These figures are estimates derived from hardware specifications and API benchmarks — Meta has not published official energy data for LLaMA 3.1 8B. Actual consumption may vary significantly depending on batching, quantisation, and infrastructure optimisations that we cannot observe from outside.
