I’m looking at the environmental impact of AI. Are a more sustainable choice compared to massive LLMs? I’ve heard that the carbon footprint of training a trillion-parameter model is astronomical. If we can get similar results from smaller versions, should that be the industry standard for ethical AI development in 2025?

Sustainability is one of the strongest arguments for the smaller approach. A massive LLM requires a staggering amount of electricity not just to train, but to serve every single request. Smaller models reduce this footprint by orders of magnitude. They can often be trained on a fraction of the hardware in a fraction of the time. If the industry prioritizes these efficient architectures, we could see a massive reduction in the water and power usage associated with data centers, making AI a much more viable long-term technology for a green economy.
But if everyone switches to small models and runs them locally, wouldn't the cumulative energy use of millions of devices eventually surpass one big data center?
Energy efficiency is definitely the future. We can't keep scaling model size indefinitely without hitting a literal power wall in our infrastructure.
Agreed, Eric. Efficiency isn't just about saving money anymore; it's about making sure the technology is actually sustainable for the planet.
That’s a valid concern, Jeffrey. However, local inference on optimized chips is generally much more efficient than the overhead of a massive cloud server. Plus, most local devices are already "on," so the marginal increase in power for a small model is much lower than spinning up dedicated H100 clusters in a data center for every query.
