Highest-quality affordable option: Claude Haiku 4.5 at $0.0330/call (10.1x the cost, 72/100 quality). Qwen 3.8 Flash is already the cheapest choice for api generation.
What drives api generation cost
Endpoint generation is the most output-heavy code task tracked here: 3K in for the spec, 6K out for handlers, types, validation, and error paths. Output pricing is therefore the whole ballgame, and the gap between a flagship and a mid-tier model at 6K output tokens compounds fast across a large API surface. Generating one resource at a time costs less than one giant multi-resource prompt.
For Qwen 3.8 Flash specifically, that means output tokens cost 3.1x more than input, at $0.47 vs $0.15 per MTok. At this use case’s 3,000/6,000 token split, output accounts for 86% of the $0.003270 per-call cost.
