No overall score, winner or cost-versus-score frontier is calculated without comparable, attributable benchmark evidence. Different test configurations appear separately. Vendor capabilities are distinct from TokenBazaar API support.
— means no published value or no matching capability. Provider token limits are not tested gateway guarantees; TokenBazaar media controls and response formats are listed separately.

- Published provider limits; maximum-capacity requests have not been independently exercised through TokenBazaar. Thinking-level variants use the same provider model; reasoning and answer tokens share the output budget.
