CoT-T5 is a language model using Flan-T5 as a base model, and CoT fine-tuned on 1.84 million rationales across 1,060 tasks from the CoT Collection. Since it was CoT fine-tuned on a large amount of rationales, it shows superior performance with CoT compared to Flan-T5. One could use CoT-T5 for (1) Solving unseen tasks in zero-shot setting, and (2) Adapting to new tasks with CoT fine-tuning.
