Unmixtraled 22B 8x linear merge
This model outputs gibberish as it was not trained under the dense configuration. Finetuning or merging is needed to make this model useful.
This is a 22B Mistral model recycling weights from mistral-community/Mixtral-8x22B-v0.1.
The model was adapted from a Mixtral architecture to a dense Mistral architecture with the same number of layers, attention heads and hidden dimensions.
Embeddings, attention, layer norms and LM head weights were taken directly from the 8x22B model, MLP weights are a linear merge of experts 0 to 7 weights.
The following named weight correspondance was used:
| Mistral weight | Mixtral weight |
|---|---|
gate_proj |
experts.{expert_num}.w1 |
down_proj |
experts.{expert_num}.w2 |
up_proj |
experts.{expert_num}.w3 |
This mergekit configuration was used to merge the experts:
