# Model Summary

This model is an intermediate training checkpoint during post-training, after the Supervised Fine-Tuning (SFT) step. For best performance, we recommend you use the [OLMoE-Instruct](https://huggingface.co/allenai/OLMoE-1B-7B-0924-Instruct) version.

Branches:
- `main`: Instruction tuned / supervised finetuned (SFT) model of https://hf.co/allenai/OLMoE-1B-7B-0924 (`main` branch)
- `load-balancing`: Ablation with load balancing loss during SFT
- `non-annealed`: Ablation starting from the checkpoint prior to annealing (branch `step1200000-tokens5033B` of https://hf.co/allenai/OLMoE-1B-7B-0924) rather than the annealed checkpoint (branch `main` of https://hf.co/allenai/OLMoE-1B-7B-0924)
