Frequently Asked Questions

What is a context window?

The context window is the maximum amount of text (in tokens) a model can process at once — including both your input and its output. Larger context windows allow processing of longer documents, codebases, or conversation histories.

GPT-4 vs Claude 3 — which is better?

It depends on the task. Claude 3.5 Sonnet generally outperforms GPT-4o on coding and instruction-following benchmarks. GPT-4o has stronger multimodal (image/audio) capabilities. Both are excellent general-purpose models.

What does "input/output price" mean?

AI APIs charge separately for the tokens you send (input) and the tokens the model generates (output). Output tokens are typically 3-5x more expensive than input tokens. The prices shown are per million tokens.
