Coding agents no longer need to rely on massive language models for locating code snippets. By delegating the search phase to a compact model, the overall workflow becomes faster and more cost-effective.
small model search
The tool jevgrep adopts this strategy: a small model processes a natural-language query, scans the repository without any prior indexing, and returns the relevant file path, code fragment, and line numbers. This pre-search step ensures that the larger model can focus exclusively on generating or completing code.
In a benchmark of ten SWE-bench tasks, jevgrep correctly solved eight of them and achieved a 25.8% reduction in total execution cost. The division of labor-search handled by the small model and generation by the large model-delivers both higher accuracy and lower resource consumption.

Conclusion
Employing a small model for code search, as demonstrated by jevgrep, proves that coding agents can achieve better performance without depending on heavyweight models for every step. This approach streamlines development pipelines and offers measurable cost savings.
