ethicalabs/xLSTM-7b-Polymath-PEFT

Model Card for xlstm-7b-instruct-phase-2

This model is a fine-tuned version of ethicalabs/xLSTM-7b-Instruct for task alignment.

It has been trained using TRL using SFT on assistant-only tokens.

The k_proj and v_proj matrices have been frozen to isolate and preserve the model's pre-trained knowledge base.

This fine-tuning focused only on the q_proj (query) and FFN matrices, adapting the model's reasoning and query-retrieval mechanisms without overwriting its core, frozen knowledge.

This experiment was designed to test the hypothesis that the model's reasoning capabilities (q_proj) could be specialized for math/code while its knowledge (k_proj, v_proj) remained intact.
