How does ERNIE Bot 4.0 compare?
Detailed Breakdown
Energy Consumption
ERNIE Bot 4.0 powers Baidu's chat assistant which reached 300M+ users. At ~1.0 Wh per query, it is comparable to Western frontier models. Running on Baidu's Kunlun AI chips provides some efficiency advantage over generic GPUs.
Power Source & Carbon
Runs on Baidu's data centres in China. China's grid carbon intensity averages ~525 g CO2/kWh — significantly higher than US or European averages — making Chinese AI inference more carbon-intensive per query even when the model itself is efficient.
Water Usage
At ~3.7 mL per query, ERNIE Bot's water footprint is elevated due to China's higher reliance on water cooling in data centres and warmer climate in key regions.
About ERNIE Bot 4.0
ERNIE Bot 4.0 is a text and chat model from Baidu, released in April 16, 2024. China's most used AI assistant with hundreds of millions of users. Each query uses 1.0 Wh of energy and produces 0.53 g of CO₂. That's about 3.3x what a Google search consumes.
These figures are estimates derived from hardware specifications and API benchmarks — Baidu has not published official energy data for ERNIE Bot 4.0. Actual consumption may vary significantly depending on batching, quantisation, and infrastructure optimisations that we cannot observe from outside.
