Why PyTorch for this
We always benchmark against the prompted baseline. If the tuned model does not clearly win on quality or cost, shipping it would be an expensive way to feel sophisticated.
PyTorch is strongest at flexibility and the widest availability of pretrained models. For custom model fine-tuning that matters because the failure modes of this kind of system tend to cluster exactly there.
The honest trade-off: production serving needs deliberate optimisation work beyond the training code. We say that up front because a stack chosen for fashion rather than fit becomes someone's migration project two years later. Integration comes before intelligence. A model that cannot reach your systems of record is a demo with good manners.
You own the code, the models where they are open-weight, and the documentation to run it without us.

- Retraining pipeline as your data grows
Questions
Should we fine-tune?
Usually not first. Prompting and retrieval solve most problems more cheaply. Fine-tuning wins for consistent format, narrow domain style, and high-volume tasks where a smaller model can replace a larger one.
How much data do we need?
For LoRA on a narrow task, often a few thousand high-quality examples. Quality matters far more than volume. We review the dataset before training anything.
Can we own the model?
With open-weight base models, yes. You hold the weights and can run them on your own infrastructure indefinitely.
Alternatives for custom model fine-tuning
Same capability, different stack. Each page states its own trade-off.
