Prompt engineering is costing you money. Learn how to fine-tune your models. Stuffing a lot of text into every single API call slows down your app because the model has to process all those tokens before it even starts generating a response. It also increases your bills, meaning you're constantly paying to repeat yourself. Instead of managing endless prompts, you bake your rules directly into the model's weights. Your apps get faster, your costs drop, and you actually own the resulting model. You don't need to be a deep ML engineer to do this anymore. I’ve been testing the new Training Agent from @FireworksAI_HQ. You just describe your task in plain English, and it handles the data validation, training, and deployment automatically.
