Cheapest viable option: Claude Sonnet 5 at $0.0330/call (80% less, 90/100 quality).
What drives math reasoning cost
Short problems, long solutions. Input is trivial and output is large because the derivation is the answer, so output rate is effectively the only price that matters. Models differ sharply in how much they show their working, which means two models at the same output rate can differ substantially in real cost per problem.
For Claude Mythos 5 specifically, that means output tokens cost 5.0x more than input, at $50.00 vs $10.00 per MTok. At this use case’s 1,500/3,000 token split, output accounts for 91% of the $0.1650 per-call cost.
