The cost of utilizing a 1 million token context window in large language models can vary dramatically, with a 600x difference observed between providers. For workloads that primarily involve reading large amounts of context, such as RAG or document summarization, the input token cost is the dominant factor. For instance, a single 800,000 token input call could cost approximately $24 on GPT-5.5 Pro, while the same call on Qwen-Flash would be around $0.04. This significant cost disparity highlights the importance of evaluating input token pricing based on actual usage volume before selecting a model for long-context tasks, as the quality difference may not always justify the price gap.
