What Is a Context Window and Why Does It Matter?
Context window = working memory
A model's context window is the total number of tokens (roughly words) it can process in a single request. This includes both your input prompt and the model's output. A model with a 128K context window can process about 170 pages of text at once, while a 1M-token model can handle roughly 1,300 pages -- enough for entire books or large codebases.
Larger context enables new use cases
With small context windows (under 32K), you must chunk documents and use retrieval-augmented generation (RAG). Large context models eliminate this complexity for many workloads: analyzing full legal contracts, reviewing entire repositories, summarizing research paper collections, or maintaining very long conversations with full history retained.
Context size vs. effective recall
Not all context is created equal. Some models perform well on "needle in a haystack" tests at their full context length, while others degrade on information retrieval when prompts get very long. The advertised context window is the maximum, but effective performance may vary. Check our leaderboard for quality scores that account for real-world performance.
Cost implications of large context
Using a large context window means sending more tokens per request, which increases cost. For example, filling a 1M-token context at $3/1M input tokens costs $3 per request. For cost-sensitive workloads, consider whether RAG with a smaller context model might be more efficient than filling a large context window end to end.

Frequently Asked Questions
A large context window model can process long inputs - from 128K tokens (about 100 pages) up to 2M tokens (about 1,500 pages). This allows analyzing entire codebases, long documents, or extensive conversation histories in a single request.
Large context models excel when you need the AI to reason across an entire document at once. RAG (Retrieval-Augmented Generation) is better for searching across massive document collections. Large context is simpler to implement but costs more per request.
No. While many models advertise 1M+ token context windows, their effective recall can vary significantly. Some models lose accuracy when important information is buried in the middle of very long contexts. Our rankings account for practical performance, not just advertised limits.
