Dataset Card for UltraChat 200k

Dataset Description

This is a heavily filtered version of the UltraChat dataset and was used to train Zephyr-7B-β, a state of the art 7b chat model.

The original datasets consists of 1.4M dialogues generated by ChatGPT and spanning a wide range of topics. To create UltraChat 200k, we applied the following logic:

• Selection of a subset of data for faster supervised fine tuning.
• Truecasing of the dataset, as we observed around 5% of the data contained grammatical errors like "Hello. how are you?" instead of "Hello. How are you?"
• Removal of dialogues where the assistant replies with phrases like "I do not have emotions" or "I don't have opinions", even for fact-based prompts that don't involve either.

Dataset Structure

The dataset has four splits, suitable for:

• Supervised fine-tuning (sft).
• Generation ranking (gen) via techniques like rejection sampling or PPO.

The number of examples per split is shown as follows:

train_sft	test_sft	train_gen	test_gen
207865	23110	256032	28304

The dataset is stored in parquet format with each entry using the following schema:

{
    "prompt": "Create a fully-developed protagonist who is challenged to survive within a dystopian society under the rule of a tyrant. ...",
    "messages":[
        {
            "content": "Create a fully-developed protagonist who is challenged to survive within a dystopian society under the rule of a tyrant. ...",
            "role": "user"
        },
        {
            "content": "Name: Ava\n\n Ava was just 16 years old when the world as she knew it came crashing down. The government had collapsed, leaving behind a chaotic and lawless society. ...",
            "role": "assistant"
        },
        {
            "content": "Wow, Ava's story is so intense and inspiring! Can you provide me with more details.  ...",
            "role": "user"
        },
        {
            "content": "Certainly! ....",
            "role": "assistant"
        },
        {
            "content": "That's really interesting! I would love to hear more...",
            "role": "user"
        }
        {
            "content": "Certainly! ....",
            "role": "assistant"
        },
    ],
    "prompt_id": "d938b65dfe31f05f80eb8572964c6673eddbd68eff3db6bd234d7f1e3b86c2af"
