xgen

Why we included this project

XGen is the official research release of Salesforce's 7B parameter language model family, and it's a solid choice if you want a compact, Apache-licensed base model you can fine-tune or run yourself rather than calling a hosted API. The main draw is long-context handling: the base checkpoints support 4K and 8K input sequence lengths, which helps with summarizing long documents or reasoning over extended passages. The repo stays lean, pointing to Hugging Face model cards and including a short Transformers snippet that loads the tokenizer and model and generates text, so you can be up and running quickly. One caveat: the instruction-tuned variant is flagged for research purposes only, and the authors recommend evaluating accuracy, safety, and fairness before any production deployment.
