Which model should you use?
Start with the token cost for your workload, the context you need, and supported input types. A lower price or larger context window does not establish better answer quality.
To compare answers, open each model in a separate chat and use the same prompt. Token tables use published specs and estimates; any measured AA results above are a separate benchmark.
