# Chat

> Multi-turn conversations with persistent history.

# dria chat

Have multi-turn conversations with persistent history. Each conversation is stored locally at `~/.dria/chats/` and can be continued later.

## Start a new conversation

```bash theme={null}
dria chat -m qwen3.5:9b "What is Rust?"
```

This prints the response and a conversation ID (e.g., `a1b2c3d4`).

## Continue a conversation

Use the conversation ID from above:

```bash theme={null}
dria chat a1b2c3d4 "Tell me more about ownership"
```

The full message history is sent with each request, so the model has context from previous turns.

## Read conversation history

```bash theme={null}
dria chat a1b2c3d4
```

## List all conversations

```bash theme={null}
dria chat list
```

## Delete a conversation

```bash theme={null}
dria chat delete a1b2c3d4
```

## System prompts

Set a system prompt when starting a new conversation:

```bash theme={null}
dria chat -m qwen3.5:9b --system "You are a helpful coding assistant" "How do I read a file in Python?"
```

The system prompt persists for the entire conversation.

## Piping

```bash theme={null}
echo "explain monads" | dria chat -m qwen3.5:9b
```
