TeTO-MS-8x7b-iMat-GGUF
Weighted quants were made using the full precision fp16 model and groups_merged_enhancedV3.
Tesoro + Typhon + OpenGPT
Presenting a Model Stock experiment combining the unique strengths from the following 8x7b Mixtral models:
- Tess-2.0-Mixtral-8x7B-v0.2 / migtissera / General Purpose
- Typhon-Mixtral-v1 / Sao10K / Creative & Story Completion
- Open_Gpt4_8x7B_v0.2 / rombodawg / Conversational
Recommended Template
- Basic: Alpaca Format
- Advanced: See context/instruct/sampler settings in our new Recommended Settings repo.
- Huge shout out to rAIfle for his original work on the Wizard 8x22b templates which were modified for this model.
Methodology
[I]nnovative layer-wise weight averaging technique surpasses state-of-the-art model methods such as Model Soup, utilizing only two fine-tuned models. This strategy can be aptly coined Model Stock, highlighting its reliance on selecting a minimal number of models to draw a more optimized-averaged model (From arXiv:2403.19522)
- Methodology and merging process was based on the following paper - Model Stock: All we need is just a few fine-tuned models
- Initial model selection was based on top performing models of Mixtral architecture covering a variety of use cases and skills
- Base model (Mixtral Instruct 8x7b v0.1) was chosen after outperforming two other potential base models in terms of MMLU benchmark performance.
Output
This is a merge of pre-trained language models created using mergekit.
