About StableLM
This GitHub repository from Stability AI contains the development work for the StableLM series of language models. It publishes model checkpoints, a technical report, training configuration files, and zero-shot evaluation results. The README states that the repository will be updated with new checkpoints as they are released.
The main model described is StableLM-3B-4E1T, a 3 billion parameter decoder-only transformer. It was trained on 1 trillion tokens over 4 epochs to study how repeated data affects downstream performance. The repository also lists earlier StableLM-Alpha models, a StableVicuna-13B fine-tune, and a 7B chat model that can be tried on Hugging Face Spaces. The README says more models are coming, and the page does not list pricing.
Key features
- Hosts the StableLM language model series with ongoing checkpoint releases
- StableLM-3B-4E1T: 3 billion parameter decoder-only transformer trained on 1 trillion tokens
- Technical report describing model architecture, tokenizer, and training data mixture
- YAML configuration file with complete hyperparameter settings for StableLM-3B-4E1T
- Zero-shot evaluation results compared with other open models, with full JSON outputs
- StableVicuna-13B RLHF fine-tune, with delta weights over Llama released separately
Best for: Researchers and developers who want to study, reproduce, or fine-tune open-source language models.
Good for
- Publishes the technical report, training configuration, and full evaluation outputs
- Model licenses are stated for each release
- Open source under the repository license
Watch out for
- The README states that more models are coming, so the listed set is incomplete
- The StableVicuna delta weights are under a non-commercial license (CC BY-NC-SA-4.0)
- The README recommends fine-tuning the base StableLM-3B-4E1T model for downstream tasks
