I don't think this is an issue? The reasoning for this is that in MainActivity we can add the system prompt first before any conversational history.

Summary: Pull Request resolved: #4721 To provide more conversational type output, we now include previous prompt/responses as part of our input into the `generate()` by the [Llama3 prompt formatting ](https://llama.meta.com/docs/model-cards-and-prompt-formats/meta-llama-3/). 1. Currently we look back at the past 2 conversations (i.e. `CONVERSATION_HISTORY_MESSAGE_LOOKBACK`) 2. This is for text only prompt and responses. 3. Supports if user closes + re-opens app again. 3. As part of this needed to separate out how `prompt` is placed in the `generate()` function since system prompt is always first, followed by conversation history (if present) and then current prompt. Multi-turn format (with example from [Llama 3 Model Card](https://llama.meta.com/docs/model-cards-and-prompt-formats/meta-llama-3)): ``` <|begin_of_text|><|start_header_id|>system<|end_header_id|> You are a helpful AI assistant for travel tips and recommendations<|eot_id|><|start_header_id|>user<|end_header_id|> What is France's capital?<|eot_id|><|start_header_id|>assistant<|end_header_id|> Bonjour!
