What are the benefits of building a large language model specific to your organization rather than using a third party vendor's model?

Building your own large language model (LLM) reduces security risks from data leakage, which could allow others to access your proprietary information. Building an in-house LLM also creates value internal to your organization rather than delivering that value (in the form of your data) to a third party. The answers from a custom LLM will also be more valid and specific to your organization. Finally, building your own LLM can be more cost effective than paying for each API request to a third party solution.
