# LongCePO Chatbot with Sambanova Backend

This is a simple chatbot interface demonstrating the LongCePO (Long-Context Planning and Optimization) method using a Sambanova model (`Llama-4-Maverick-17B-128E-Instruct`) as the backend LLM.

## How it works

The LongCePO method is designed to handle long contexts (potentially millions of tokens) by:
1.  **Planning:** Decomposing the initial query into sub-questions.
2.  **MapReduce:** Answering each sub-question by processing chunks of the long context, summarizing relevant information, and aggregating results.

This application takes a long text context and a query based on that context. It then uses the modified `longcepo` plugin (originally from the `optillm` repository) to generate an answer using the Sambanova API.

## How to use

1.  **(Optional)** Enter a system prompt to guide the chatbot's behavior.
2.  Paste the long text document into the **Context** box.
3.  Enter your question based on the provided context into the **Query** box.
4.  Click **Submit**.

The chatbot will process the request using the LongCePO pipeline and display the final answer.

**Note:** Processing long contexts can take some time depending on the length of the context and the complexity of the query.

## API Key

This application requires a Sambanova API key to function. The key should be stored as a Hugging Face Space Secret named `SAMBANOVA_API_KEY`.
