Pricing verification and limits

Audited October 3, 2026 using the September 28 pricing table, model list, and release announcements. Old indexed July pricing for DeepSeek V4 differs; the catalog uses the newer table. Limits are recorded using the catalog’s existing decimal K convention. DeepSeek V4.1 Flash peak periods are Monday–Friday, 09:00–12:00 and 14:00–18:00 UTC+8; all other periods are off-peak. Its catalog prices are null because the current schema cannot represent a time-based rate. This means unknown to the cost calculator, not free. April Seed Lite audio input / cached audio is $3.75 / $0.75, and April Seed Mini is $1.50 / $0.30; both double above 128K. These differ from the catalog’s non-audio rates. Explicit cache storage is an additional $0.0083 per million tokens per hour; implicit caching has no storage fee. Storage and audio charges require separate reconciliation. Flex halves input/output prices on Seed 2.1 Turbo and DeepSeek V4 GA while leaving cache prices unchanged. It cannot be encoded as a uniform multiplier across all token types. The catalog records standard rates. Batch discounts also leave cached input unchanged; do not halve the whole bill. GPT OSS’s model page lists a cache rate while the current aggregate price table shows no cache rate; no cache discount is assumed in the catalog.

Retirements

The deprecation notice confirms Kimi K2, Kimi K2 Thinking, and DeepSeek R1 snapshots ceased service May 13, 2026; they have been removed. Seed 1.6, Seed 1.8, February Seed Lite/Mini, DeepSeek V3.2, GLM 4.7, and GPT OSS retire November 11, 2026 and remain listed for migration. The model-list page already labels some of them “Retired”; the dated deactivation notice governs the catalog. Seed Mini’s February snapshot is already unavailable in eu-west-1, but remains available on the configured ap-southeast-1 endpoint until its scheduled shutdown.
