# OpenAssistant Conversations Dataset (OASST1)
## Dataset Description
- **Homepage:** https://www.open-assistant.io/
- **Repository:** https://github.com/LAION-AI/Open-Assistant
- **Paper:** TBA on April 17, 2023
### Dataset Summary
In an effort to democratize research on large-scale alignment, we release OpenAssistant
Conversations (OASST1), a human-generated, human-annotated assistant-style conversation
corpus consisting of 161,443 messages distributed across 66,497 conversation trees, in
35 different languages, annotated with 461,292 quality ratings. The corpus is a product
of a worldwide crowd-sourcing effort involving over 13,500 volunteers.
Please refer to our paper for further details.
### Dataset Structure
This dataset contains demonstrations of human-assistant conversations which were collected
on the [open-assistant.io](https://www.open-assistant.io/) website until April, 12 2023.
Conversations are exported as conversation trees with messages as nodes.
The root node of a conversation tree is called the initial prompt. Each message can have
multiple replies. Nodes with more than one reply can have a `rank` field indicating the
aggregated user preference (the most preferred message has rank 0).
All messages have a role property which can either be "assistant" or "prompter". The roles in
conversation threads from prompt to leaf node are stricly alternating between "prompter" and "assistant".
### JSON Example: Message
For readability the following JSON examples are shown formatted with indentation on multiple lines.
Objects are stored without indentation on a single lines in the actual jsonl files.
```json

Please refer to [oasst-data](https://github.com/LAION-AI/Open-Assistant/tree/main/oasst-data) for
details about the data structure and Python code to read and write jsonl files containing oasst data objects.
## Main Dataset Files
Conversation data is provided either as nested messages in trees (extension `.trees.jsonl.gz`)
or as flat list (table) of messages (extension `.messages.jsonl.gz`).
Full conversation trees can be reconstructed from flat messages by using the `parent_id`
and `message_id` properties to identify the parent-child relationship of messages. The `message_tree_id`
and `tree_state` properties (only present in flat messages files) can be used to find all
all messages of a message tree or to select trees by their state.
### Ready For Export Trees
```
2023-04-12_oasst_ready.trees.jsonl.gz 10364 trees with 88838 total messages
2023-04-12_oasst_ready.messages.jsonl.gz 88838 messages
```
Trees in `ready_for_export` state without spam and deleted messages including message labels.
The oasst_ready-trees file is normally sufficient for supervised fine-tuning (SFT) & reward model (RM) training.
### All Trees
```
2023-04-12_oasst_all.trees.jsonl.gz 66497 trees with 161443 total messages
2023-04-12_oasst_all.messages.jsonl.gz 161443 messages
```
All trees including those in states `prompt_lottery_waiting` (trees that consist of only one message, namely the inital prompt),
`aborted_low_grade` (trees that stopped growing because the messages had low quality), and `halted_by_moderator`.
### Supplemental Exports: Spam & Prompts
```
2023-04-12_oasst_spam.messages.jsonl.gz
```
Messages which were deleted or have a negative review result (`"review_result": false`).
Beside low quality a frequent reason for message deletion is a wrong language tag.
```
2023-04-12_oasst_prompts.messages.jsonl.gz
```
All non-deleted initial prompt messages with positile spam review result of trees in `ready_for_export` or `prompt_lottery_waiting` state.

OpenAssistant Conversations incorporates 35 different languages with a distribution of messages as follows:
