reacted to AC-723's post with š„ 1 day ago MixtureKit 1.1 is out š Turn the fine-tuned models you already have on the Hub into one Mixture-of-Experts model.
pip install mixturekit
Give it a base model and its fine-tunes (math, code, a language...). MixtureKit merges them, trains the routers that pick an expert for every token, and shows you what they learned:
š§© 3 composition methods behind one YAML: Branch-Train-MiX, Mixtral-style MoE, Branch-Train-Stitch
š» Merges stream the experts tensor by tensor: they run on a laptop
šÆ Router training with a load balancing loss, optional LoRA
š A routing visualizer: in the image, two Nile 4B experts split a mixed Egyptian sentence, Arabic script to one expert, Arabizi to the other
š¦ Export to Mixtral / Qwen3-MoE, then GGUF for llama.cpp
š¤ mixturekit push uploads the result with a generated model card
ā
Llama 3, Qwen 2.5/3/3.5, Gemma 3/4 experts; tested on transformers 4.52 to 5.19
In the paper, a BTX model built with MixtureKit outperforms the dense baselines on multiple benchmarks.
