Why Azure OpenAI for this
Most teams who ask for fine-tuning need better prompting and retrieval instead. We check that first, and say so when it is true. It saves you a quarter and a budget line.
Azure OpenAI is strongest at enterprise compliance posture and integration with existing Microsoft estates. 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: quota management and regional capacity can constrain scaling at short notice. We say that up front because a stack chosen for fashion rather than fit becomes someone's migration project two years later. We build the smallest thing that proves the case, put it in front of real users, and expand only what earns its keep.
Six weeks to something running in production, not six quarters to a strategy document.

We are not a reseller for Microsoft and hold no commission on this choice. Where a different option fits your workload better, the recommendation will say so. That is the entire value of asking us.
What is included
- Honest assessment of whether fine-tuning is warranted
- Training data curation and quality review
- LoRA or full fine-tune as the workload justifies
- Evaluation against the prompted baseline
- Inference deployment and cost comparison
- 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.
