Context window overflow: Breaking the barrier

Security Blog



This article discusses context window overflow (CWO) in large language models (LLMs) and its implications for generative AI systems.

Specifically, the article covers:

  • Key concepts in generative AI such as LLMs, tokenization, context windows, retrieval augmented generation (RAG), and LLM hallucinations
  • How CWO occurs when the total number of input and output tokens exceeds the model's predefined context window size, causing loss of context
  • Examples demonstrating token complexity leading to overflow, and prompt injection using long prompts to retrieve sensitive information
  • Recommendations to mitigate CWO, including token limits, input validation, streaming LLMs, and monitoring
  • The importance of understanding CWO limitations to harness the potential of AI models effectively
