Local Qwen 3.8 27B vs DeepSeek Flash API: Is local good enough?

A comparison between running a local Qwen 3.8 27B model and using the DeepSeek Flash API for daily work suggests that local models are now "good enough." Testing across 25 paired tasks and four workloads showed that both models achieved 10/10 agentic runs fully green for completion tasks and identically fixed all four bugs in 5/5 rounds. The primary difference noted was cost, with local runs incurring only electricity expenses, while the cloud-based 12-task suite cost 0.14 credits.

This report uniquely quantifies the performance parity between a local Qwen 3.8 27B model and the DeepSeek Flash API, unlike prior qualitative assessments.
