long-t5-tglobal-base-synthsumm_direct

Fine-tuned on a synthetic dataset of curated long-context text and GPT-3.5-turbo-1106 summaries spanning multiple domains + "random" long-context examples from pretraining datasets

Note: this model has not been fine-tuned on any other summarization datasets, just the synthsumm data
