Fine-tuning a small Qwen vision model is easy — hosting it meant 10 days of idle GPU rent

Developer allenling fine-tuned a small Qwen vision model for a specific task and found training easy but hosting painful: they rented a GPU for 10 days just to test the product despite almost nonexistent traffic.
They ask whether people actually run self-hosted fine-tuned small models in production or default to hosted APIs, how to avoid paying for idle GPUs, and which small models others use for what. The post highlights the 'cheap to train, expensive to serve' cost pain of fine-tuned small models.
