A 2025 study by Chroma revealed that large language models, including GPT-4.1, Claude 4, Gemini 2.5, and Qwen3, perform worse as their input context increases. This finding contradicts the prevailing industry assumption that larger context windows universally improve AI performance. The study tested 18 frontier models, all of which showed degraded performance with greater input lengths, prompting a reevaluation of how AI models process information. AI
IMPACT Challenges the assumption that larger context windows improve AI performance, necessitating new approaches to information feeding.
