What it is
A frankenmerge: layers stacked from existing models into a new 18B model, then healed with QLoRA so the stacked layers work together again. It's released under Apache-2.0.
Against advice
The frontier models I consulted advised against attempting it. I tried it anyway, measured it, and published it. It became one of my most downloaded releases.
Reproducible
The full process is written up step by step in MERGE_PROCESS.md on the model repository, so anyone can reproduce or extend it.
