Every query an enterprise AI application processes, every correction a subject matter expert makes to its output — that interaction is training data. Most organizations are not capturing it. The production workflows companies have already built are generating a continuous signal that improves AI models, and it is disappearing.San Francisco-based Empromptu AI on Thursday launched Alchemy Models with a straightforward premise: the AI applications enterprises are already building are generating training data, and most of it is going to waste. The platform captures that signal automatically, routing validated outputs from subject matter experts back into a fine-tuning pipeline that improves the model over time. Enterprises own the resulting weights outright.It sits in different territory from both RAG and traditional fine-tuning. RAG retrieves external context at inference time without modifying model weights. Traditional fine-tuning changes weights but requires separately assembled labeled datasets and a dedicated ML pipeline. Alchemy does the latter continuously, using the enterprise application itself as the data source.Companies adopting foundation model APIs face three compounding constraints: inference costs that scale with usage, no ownership of the models their data is effectively training, and limited ability to customize behavior for domain-specific tasks. Empromptu CEO Shanea Leven says those constraints are widely felt but rarely addressed.”Every customer, everybody that I talk to, is like, how am I not going to get disrupted? How am I going to protect my business? And they just don’t see the path,” Leven told VentureBeat in an exclusive interview.How Alchemy builds a model from a running applicationMost custom model training approac …
