To clear conversation history or context during a live OpenAIRealtime conversation, you can use the following methods depending on your requirements: • Clearing Individual Conversation Items: ◦ JavaScript/TypeScript:

// Delete a specific conversation item by ID
session.conversation.item.delete(itemId);

◦ Python:

# Update chat context (this can include removing items)
await session.update_chat_ctx(new_chat_ctx)

• Clearing Input Audio Buffer: ◦ JavaScript/TypeScript:

// Clear the input audio buffer
session.inputAudioBuffer.clear();

◦ Python:

# Clear the input audio buffer
session.clear_audio()

• Truncating Conversation Items: ◦ JavaScript/TypeScript:

// Truncate a conversation item
session.conversation.item.truncate(itemId, contentIndex, audioEnd);

◦ Python:

# Truncate a conversation item
session.truncate(message_id=message_id, audio_end_ms=audio_end_ms)

• Complete Context Reset: ◦ To completely reset the conversation context, delete all existing conversation items and optionally provide a new chat context. In Python, this can be achieved by calling

update_chat_ctx

with an empty or new

ChatContext
