What Is SODA Foundation?
SODA Foundation is an open-source project under the Linux Foundation. Its mission is simple: make data management and storage work smoothly across cloud, edge, and on-premise systems
.
Think of it as a "universal translator" for data storage. Instead of locking your data into one vendor's system, SODA helps you move and manage data freely across different platforms
.
Founded in 2020 (originally called OpenSDS), SODA now includes major players like Huawei, Fujitsu, NTT Communications, Toyota, Sony, and China Unicom
.
What Is Aitra?
Aitra is an open-source project by SODA Foundation that measures how much energy AI systems use.
Here's the problem Aitra solves: When you run AI models (like ChatGPT-style tools), they consume massive amounts of GPU power. But most businesses have no idea how much energy each AI task actually costs.
Aitra fixes this by tracking "energy per output token" — basically, how many joules of electricity it takes to generate each piece of AI output
.
Aitra in Plain English
| What Aitra Does | Why It Matters |
|---|---|
| Measures GPU energy in real-time | Know exactly where your AI costs come from |
| Attributes energy to specific workloads | Chargeback per team or project |
| Runs on Kubernetes | Works with modern cloud infrastructure |
| Open source (Apache 2.0) | Free to use and modify |
Why Should You Care About AI Energy?
If you run any AI tools on your website or servers, energy costs are real money. Aitra helps you:
Optimize efficiency — Find which AI models or configurations waste the most power
Report carbon usage — Meet ESG (Environmental, Social, Governance) requirements
Reduce bills — Better scheduling = lower electricity costs
Aitra was featured at KubeCon Japan 2026, where companies like SoftBank and NTT DOCOMO showed interest in using it for their AI data centers
.
Aitra's Key Metric: Joules Per Token
The core measurement is called aitra_j_per_token — joules (energy) divided by output tokens (work done)
.
Lower is better. A lower number means your AI is more efficient — it produces more output for less energy.
Aitra also tracks:
aitra_idle_time_ratio— How often GPUs sit unusedaitra_gpu_power_watts— Real-time power draw
These metrics integrate with Kubernetes and tools like KAI Scheduler to automatically place AI workloads on the most efficient nodes
.
Who Should Use SODA Foundation and Aitra?
Perfect for you if:
You run AI models on GPUs (cloud or on-premise)
Your electricity bill for AI is growing
You need to report carbon/energy usage
You want to optimize costs across teams
Not needed if:
You only use basic website hosting
Your AI usage is minimal (under a few hours daily)
The Bigger Picture: Green AI Matters
As AI becomes more common, energy consumption is exploding. Data centers already use ~1-2% of global electricity, and AI is pushing that higher.
Aitra represents a shift toward accountable AI — where companies can measure and reduce their AI carbon footprint, not just chase performance.
