# Arcee-SuperNova-Medius |
|
|
|
Arcee-SuperNova-Medius is a 14B parameter language model developed by Arcee.ai, built on the Qwen2.5-14B-Instruct architecture. This unique model is the result of a cross-architecture distillation pipeline, combining knowledge from both the Qwen2.5-72B-Instruct model and the Llama-3.1-405B-Instruct model. By leveraging the strengths of these two distinct architectures, SuperNova-Medius achieves high-quality instruction-following and complex reasoning capabilities in a mid-sized, resource-efficient form. |
|
|
|
SuperNova-Medius is designed to excel in a variety of business use cases, including customer support, content creation, and technical assistance, while maintaining compatibility with smaller hardware configurations. It’s an ideal solution for organizations looking for advanced capabilities without the high resource requirements of larger models like our SuperNova-70B. |

|
## Distillation Overview |
|
|
|
The development of SuperNova-Medius involved a sophisticated multi-teacher, cross-architecture distillation process, with the following key steps: |
|
|
|
1. **Logit Distillation from Llama-3.1-405B-Instruct**: |
|
- We distilled the logits of Llama-3.1-405B-Instruct to Qwen2.5-14B using KL-divergence as the loss function. This allowed us to capture the nuanced distribution of Llama's outputs while adapting them to Qwen's architecture. |
|
|
|
2. **Logit and Hidden State Distillation from Qwen2.5-72B-Instruct**: |
|
- Further distillation was performed using a combination of logit and hidden state distillation from Qwen2.5-72B-Instruct to ensure that SuperNova-Medius inherited the strong instruction-following capabilities and domain-specific knowledge of Qwen2.5. |
|
|
|
3. **Cross-Architecture Vocabulary Alignment**: |
|
- Using `mergekit-tokensurgeon`, we aligned the vocabularies and hidden states of both teacher models, allowing for seamless integration of knowledge across the different architectures. This enabled SuperNova-Medius to effectively combine the strengths of both models. |
|
|
|
4. **Final Fusion and Fine-Tuning**: |
|
- After aligning the vocabularies, a final fusion and fine-tuning step was conducted, using a specialized dataset from [EvolKit](https://github.com/arcee-ai/EvolKit) to ensure that SuperNova-Medius maintained coherence, fluency, and context understanding across a broad range of tasks. |
