Mesh-v0.1-2x2 (Stage 002)

Introducing mesh

This is our first ever model! Allow us to explain how the mesh architecture works in detail.

• Neural Mesh extends the concept of Mixture of Experts by allowing bidirectional expert communication.

• The experts are shared in a bidimensional grid (2x2, 4x4, etc.) layout, that allows for them to communicate with their neighbors using the "Neighbor Exchange" method.

• Just like MoE models, Mesh models have dynamic routing, and through the routing_k parameter you can define the amount of active parameters. For this model (2x2):

  • top-1 routing: 173M active parameters
  • top-2 routing: 242M active parameters (default)
  • dense routing: 302M active parameters

Here's how the mesh architecture works:

Evaluation

Disclaimer

This small language model is just a proof-of-concept, paving the way to the final release, which is likely to happen in Q4 2025, and include more models and better support from external libraries such as Transformers and Llama.cpp.
