## Summary

Exowatt, a solar energy provider for AI data centers, built a reusable AI pipeline using Amazon SageMaker’s serverless model customization. The company fine-tuned Qwen3-1.7B for edge alarm triage and Qwen3-14B for cloud energy-market analysis, achieving higher accuracy than frontier models at up to 49× lower cost per decision. Both models run autonomously, citing specific data rows to justify claims, and avoid guesswork by abstaining when evidence is insufficient. The pipeline cuts model development from months to days by eliminating GPU provisioning and container-building steps, enabling rapid iteration across thousands of deployed sites.

## Key points

- Fine-tuned Qwen3-1.7B model outperformed frontier models on edge alarm triage with 0.911 macro-F1 at $0 cost per 1,000 decisions
- Qwen3-14B model achieved 0.975 macro-F1 on cloud energy-market analysis, costing $0.60 per 1,000 answers vs. $29.26 for Claude Opus 4.7
- Exowatt reduced model development time from months to days by using SageMaker’s serverless fine-tuning and avoiding GPU provisioning

## Why it matters

This approach proves smaller, task-specific models can outperform large frontier models in specialized tasks, reducing costs and enabling autonomous decision-making in physical systems like energy infrastructure. It also demonstrates how serverless AI pipelines can accelerate model iteration for edge and cloud deployments.
