## sharegpt

conversations where `from` is `human`/`gpt`. (optional: first row with role `system` to override default system prompt)

```{.json filename="data.jsonl"}
{"conversations": [{"from": "...", "value": "..."}]}
```

Note: `type: sharegpt` opens special configs:
- `conversation`: enables conversions to many Conversation types. Refer to the 'name' [here](https://github.com/lm-sys/FastChat/blob/main/fastchat/conversation.py) for options.
- `roles`: allows you to specify the roles for input and output. This is useful for datasets with custom roles such as `tool` etc to support masking.
- `field_human`: specify the key to use instead of `human` in the conversation.
- `field_model`: specify the key to use instead of `gpt` in the conversation.

```yaml
datasets:
    path: ...
    type: sharegpt

    conversation: # Options (see Conversation 'name'): https://github.com/lm-sys/FastChat/blob/main/fastchat/conversation.py
    field_human: # Optional[str]. Human key to use for conversation.
    field_model: # Optional[str]. Assistant key to use for conversation.
    # Add additional keys from your dataset as input or output roles
    roles:
      input: # Optional[List[str]]. These will be masked based on train_on_input
      output: # Optional[List[str]].
```
