# 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**:
- We distilled the logits of Llama 3.1 405B using an offline approach.
- The top K logits for each token were stored to capture most of the probability mass while managing storage requirements.
2. **Cross-Architecture Adaptation**:
- Using `mergekit-tokensurgeon`, we created a version of Qwen2.5-14B that uses the vocabulary of Llama 3.1 405B.
- This allowed for the use of Llama 3.1 405B logits in training the Qwen-based model.
3. **Distillation to Qwen Architecture**:
- The adapted Qwen2.5-14B model was trained using the stored 405B logits as the target.
4. **Parallel Qwen Distillation**:
- In a separate process, Qwen2-72B was distilled into a 14B model.
5. **Final Fusion and Fine-Tuning**:
- The Llama-distilled Qwen model's vocabulary was reverted to Qwen vocabulary.
- After re-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.
## Performance Evaluation
Below are the benchmark results of SuperNova-Medius compared to similar models in its class:
| Model | Average | IFEval | BBH | GPQA | MMLU Pro | MuSR | Math Level 5 |
| --- | --- | --- | --- | --- | --- | --- | --- |
| Mistral-Small 2409 | 0.423 | 0.628 | 0.581 | 0.333 | 0.410 | 0.406 | 0.181 |
| Supernova-Lite | 0.427 | 0.786 | 0.511 | 0.306 | 0.388 | 0.415 | 0.155 |
| Qwen2.5-14B-Instruct | 0.450 | 0.827 | 0.623 | 0.358 | 0.490 | 0.403 | 0.000 |
| Supernova-Medius | **0.480** | **0.832** | **0.631** | **0.359** | **0.502** | **0.402** | **0.152** |
SuperNova-Medius performs exceptionally well in instruction-following (IFEval) and complex reasoning tasks (BBH), demonstrating its capability to handle a variety of real-world scenarios. It outperforms Qwen2.5-14B and SuperNova-Lite in multiple benchmarks, making it a powerful yet efficient choice for high-quality generative AI applications.
