This model is a fine-tuned version of ontocord/1.7b-MixtureVitae-300BT-v1 on the smoltalk, the longalign and the sealong datasets. The model extends the context length of base model from 4096 to 16384 tokens.

NOTE: Because the post-training data is no longer strictly public domain, cc-by and .gov, please do not depend on these constraints on the model output. This is an experimental model.
