All You Need to Know to Build Your First LLM App by Dominik Polzer

There may be reasons to split models to avoid cross-contamination of domain-specific language, which is one of the reasons why we decided to create our own model in the first place. Although it’s important to have the capacity to customize LLMs, it’s probably not going to be cost effective to produce a custom LLM for every use case that comes along. Anytime we look to implement GenAI features, we have to balance the size of the model with the costs of deploying and querying it. The resources needed to fine-tune a model are just part of that larger equation.

The Apache 2.0 license covers all data and code generated by the project along with IBM’s Granite 7B model. Project maintainers review the proposed skill, and if it meets community guidelines, the data is generated and used to fine-tune the base model. Updated versions of the models are then released back to the community on Hugging Face.

In the second phase of the project, the company deleted harmful content from the dataset. It detected such content by creating a safety threshold based on various textual criteria. When a document exceeded the threshold, Zyphra’s researchers deleted it from the dataset.
