A: I've addressed a similar question here:
https://appsumo.com/products/sharpapi/questions/custom-api-wokflows-1260408/

Currently, there’s no way for users to independently train their own custom LLMs through SharpAPI. However, we do offer this service for enterprise-level customers. Training a model requires uploading extensive datasets, and as you know, this is one of the most resource-intensive and costly operations. The costs are highly variable, depending on the volume of data, which makes it impossible to offer a standard pricing model for this service.

That said, we are exploring the idea of adding an experimental custom workflow builder to the platform. This feature might eventually allow users to attach training data, but it’s still in the conceptual stage. Realistically, this wouldn’t happen before late Q1 or Q2 of 2025. Stay tuned!
