Open sourcing AI models can lead to increased innovation, accessibility, transparency, and community building. However we need a mechanism to train more capable models in an efficient and modular way.

The proposed method that we call Multi-Domain Expert Learning (MDEL) for open source language models involves branching from a base model, training each branch independently on a specific domain for specific layers or other adapters, and merging the trained models at the end. Additionally, the specific layers or adapters are kept as experts, with a classifier used as a router to activate the experts during inference. This approach makes it possible to easily increase expertise of a model, to independently train more "adapters", and to reuse previously trained experts and models without retraining, resulting in a modular and efficient system.

In this effort, we seek international labs and open source aligned researchers and companies in various countries to each train a set of domain experts of their choosing, thereby enabling international participation and knowledge sharing. This will also result in lower costs for training and a lower environmental impact due to reuse and lower energy usage. Currently we have volunteers from four continents and are looking for more.

We will be using a varient of the c-BTM ( method and will be focusing on models ranging from 7-70B parameters.

In some of our models, we will also be adding multi-lingual, multi-modal abilities for both understanding and generation with context lengths of 8K-35K tokens.

Languages will include: hi, vi, en, ja, fi. We may add others if compute is available.

** Why did we change the term "Layer" to "Learning"? Because we are exploring, in addition to layerwise experts, also working with different adapters and architecture like Flamingo (, EMU ( and a novel multi-node architecture for training loras we call lora-x, which will allow us to swap out different component experts to improve the performance of the model.
