How does Sora 2 compare?
Detailed Breakdown
Energy Consumption
Sora 2 generates video with synchronised dialogue and sound effects — a major step beyond Sora's silent video. At ~600 Wh per 10-second clip, the addition of audio generation adds approximately 20% overhead. Sora 2 secured a $1B Disney partnership in Dec 2025. Note: both the app and API are being shut down in 2026.
Power Source & Carbon
Runs on Azure high-density GPU clusters. The combined video+audio pipeline requires sustained multi-GPU computation.
Water Usage
At ~2,160 mL (~2.2 litres) per clip — more than a large bottle of water for 10 seconds of video.
About Sora 2
Sora 2 sits at the high end of AI energy consumption at 600.0 Wh per generating one short video clip — over 2000x what a Google search uses. OpenAI's video generation model, released in September 30, 2025, synchronised dialogue and sfx — disney partnership ($1b). The extreme energy cost reflects the computational complexity of video generation: generating coherent frames across both space and time.
These figures are estimates derived from hardware specifications and API benchmarks — OpenAI has not published official energy data for Sora 2. Actual consumption may vary significantly depending on batching, quantisation, and infrastructure optimisations that we cannot observe from outside.
Sora 2 in Context
The video generation premium
One Sora 2 generation uses 600.0 Wh — the equivalent of 50 full smartphone charges. Video generation requires running a diffusion model across both spatial and temporal dimensions, making it fundamentally more compute-intensive than text or image tasks. This is not an efficiency problem to be solved; it is an inherent characteristic of the task.

Calculate My ComputeFrequently Asked Questions
How much energy does Sora 2 use per query?
Each Sora 2 query consumes approximately 600.0 Wh of energy. This is 2000x more than a traditional Google search (~0.3 Wh).
What is Sora 2's carbon footprint?
Based on the carbon intensity of Azure / Multi-cloud, each query produces approximately 262.0 g of CO2. The grid in this region has a carbon intensity of 450 g CO2/kWh with 25% renewable energy.
How much water does Sora 2 use?
Each query consumes approximately 2.16 L of water, primarily used for cooling the data centers that process the request.
How does Sora 2 compare to a Google search?
A Sora 2 query uses 2000x more than a Google search in terms of energy. A Google search uses approximately 0.3 Wh, while Sora 2 uses 600.0 Wh.
