Some companies don’t use popular language models provided by big players such as OpenAI, Meta, and Google, but have invested in their own models. These models aren’t well known, though some, like A121 Labs, have over 10,000 developers already using them.
On the AI Mode website, we often reference applications using these models as Proprietary Models.
Examples of apps using their own models:
