Context Window Size vs. Cost
The relationship between context window and cost is not linear. Some models offer massive context at budget prices, while others charge a premium for every additional token.
| Model | Context Window | Max Documents (50K each) | Input Cost / 1M | Best For |
|---|---|---|---|---|
| Llama 4 Scout | 1M tokens | ~200 documents | $0.18 | Massive batch processing |
| Gemini 3.1 Pro | 1M tokens | ~200 documents | $2.00 | High-quality large-doc analysis |
| Gemini 2.5 Pro | 1M tokens | ~20 documents | $1.25 | Single long documents |
| Gemini 2.5 Flash-Lite | 1M tokens | ~20 documents | $0.10 | Budget large-context tasks |
| Claude Sonnet 4.6 | 200K tokens | ~4 documents | $3.00 | Premium extraction accuracy |
| GPT-4o | 128K tokens | ~2 documents | $2.50 | Moderate-size documents |
| DeepSeek V4 Pro | 128K tokens | ~2 documents | $2.18 | Budget with good accuracy |
