What drives security review cost

Security review is the code task where quality is worth paying for: a missed vulnerability costs more than the entire year's inference bill. Input is large (the code plus the threat context) and output is moderate. This is the clearest case on this list for choosing a top-ranked model over the cheapest viable one, and for not batching away the latency you need in CI.

For DeepSeek V4 Pro specifically, that means output tokens cost 3.0x more than input, at $1.98 vs $0.66 per MTok. At this use case’s 6,000/2,500 token split, output accounts for 56% of the $0.008910 per-call cost.

About DeepSeek V4 Pro

Prices are off-peak rates from api-docs.deepseek.com (read 2026-10-11). Peak-hour prices are 2x the listed input and output rates — Tokeven does not model time-of-day tiers; off-peak is used as the base. Cache hit: $0.022/MTok input. No batch discount published. Not yet benchmarked, so never recommended.
