No LLM can solve this - Lost in the Middle. Both models failed to complete the task due to the inserted nonsense paragraph in the middle of the text. The failure rate was high, but Mistral Medium came close with a 47% success rate. This test showed that even with a 2,000 token context length, the middle portion is consistently ignored. This blind test was a complete disaster. See you in my next video!


Introduction

In a blind test, two chatbot models, Model A and Model B, were tested to solve a prompt containing over 1,000 words. However, both failed to solve the task in the provided text. The article provides an in-depth analysis of the blind test and the results obtained from different models. The prompt required answering a specific question based on a paragraph of text, and the test concluded that most systems did not have the capability to perform the task.


Analysis of Results

Upon analyzing the results of the blind test, it was evident that both Model A and Model B failed to comprehend and solve the task. This was particularly noticeable as they ignored an entire paragraph in the middle of the text, which highlighted the limitations of existing language models when handling tasks contained within a lengthy context.

  • Key Takeaways:
    • Models were unable to solve tasks within the middle of a 1,000-word text.
    • Both Model A and Model B failed to understand and execute the specified prompt.
    • Chatbot Arena hosted the blind test, with the systems chosen automatically, with no external influence.
