smol_llama-220M-GQA-32k-theta

Experimental model meant to serve as a long-context speculative decoding model.

Created using BEE-spoke-data/smol_llama-220M-GQA and further pretraining at 32768 context length on togethercomputer/RedPajama-Data-1T-Sample.

This variant uses the rope theta (rope frequency base) method for context extension.
