$4/1M tokens

The sharpest bend in the price-to-score curve out of 34 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 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 Show: Budget / Balanced / Premium to control how far down that list goes - Balanced (default) only shows models at least 80% as capable as the top model; Budget loosens that to 50%; Premium tightens it to 90%. The Best Value Pick always stays visible regardless of which tier is selected. Click Update on a category page (or Update All on the home page) to refetch live data any time.
