Does anyone use fine-tuned models?

Why don’t I use fine-tuned models for anything I do?

Why don’t people use models fine-tuned for specific languages in Cursor or Windsurf?

And then from what interface will you call out to that inference?

im working my way towards it, i have a project with a complex response format (pydantic structured outputs and tool calling) and im compiling a folder full of example input/output data, once i get up to about 50 or so very curated examples, i plan to finetune 4omini

the 15 examples i have are already 99% of my tokens used, attaching every example to every prompt to get the llm to behave how i want - im expecting fine tuning to save me massively on input tokens

you are basically asking for a knowledge base. most agents are fine-tuning based on your responses and its actions. just use cursor compose or claude code.
