Pricing tiers: BytePlus ModelArk lists seed-2-0-pro-260328 at $0.50/$3.00 per MTok for prompts ≤128K, with $0.10 cache-hit input. Above 128K through 256K the full request uses $1.00/$6.00 and $0.20 cache-hit input. Standard cache storage is $0.0083 per MTok/hour. Batch is $0.25/$1.50 or $0.50/$3.00 in the same tiers, with unchanged cache-hit rates. These are BytePlus USD prices, separate from mainland Doubao tariffs; no Flex rate for this Pro SKU is confirmed.

Watch out

February 14 is the Seed 2.0 family launch, not the pinned SKU's version date. BytePlus advertises 256K context and 128K output including CoT, but text and vision tables conflict on maximum input (224K versus 256K); exact integer ceilings remain unverified. thinking.type supports enabled (default) and disabled. The effort table accepts seven values but combines conflicting default/mapping cells, so distinct effects and the omitted-effort default are not certified. Temperature/top_p overrides are ignored for this SKU. Parameters, licence and downloadable-weight status are unknown; do not inherit Lite audio support.
