よくある質問

Our comparison uses benchmark data including the Intelligence Index, feature scores, context window size, and pricing. You can filter by model, compare plans side by side, and view charts for intelligence vs price and intelligence vs features to find the best fit for your use case.

The Intelligence Index is a composite score based on Artificial Analysis benchmarking that measures reasoning, knowledge, and response quality. Higher scores indicate stronger performance on standardized evaluations. Paid plans typically score higher than free tiers.

Most major providers (Claude, ChatGPT, Gemini, Meta AI) offer free tiers with varying limits. Our comparison table shows feature scores, context windows, and capabilities for each plan. Free tiers often have smaller context windows and fewer advanced features like web search or file uploads.

Key differentiators include long context support, real-time web search, voice input/output, multimodal (image) understanding, and coding capabilities. Some excel at coding (CodeStral, o1), others at conversational accuracy (Claude) or visual understanding (Gemini).
