The sharpest bend in the price-to-score curve out of 20 models — extra dollars beyond this point buy noticeably less extra capability.

No models made this category's table - every one of its models was beaten on both price and intelligence by another maker's model here, so none reached the top 10 or the value frontier. No per-company quota forces a spot - try a different category.
How this page works
Highlights shows the true top 10 models by intelligence - no per-company
limit, so if one company genuinely has several of the top models right
now, several of its models are shown. Ranked three ways -
Intelligence, Price, and Speed - so you can see how the same lineup trades
off against each other. Each model keeps one color across all three charts.
Value (0-100) below that shows how much intelligence you get per
dollar, scaled so the best value model shown scores 100 - tables sort by
Value by default; click "Intelligence" or "Name" above one to sort by
those instead. The three calculated columns are, in full:
Cost / task = price per 1M tokens ×
tokens the model actually uses ÷ 1,000,000Value = intelligence score ÷ cost per taskPrice = (3 × input + output) ÷ 4,
per 1M tokens
The Best Value Pick is the sharpest bend in the
price-to-intelligence curve across every model in the category. The
table also includes every other model on that same efficiency frontier
(tagged Frontier) even if it didn't score high enough to crack
the top 10 - a cheap, well-balanced model would otherwise be invisible
no matter how the table is sorted. Use the Capability buttons to
control how far down that list goes - All (default) filters nothing;
Flagship keeps models within 10% of the best score, Strong within 20%,
Broad within 50%. The Best Value Pick
always stays visible regardless of which tier is selected. Click
