| Price basis | USD is FX-derived from StreamLake's RMB list price (¥1 in / ¥0.2 cached / ¥4 out per 1M) at 6.7476 CNY/USD (2026-08-07); re-checked on FX drift, not a promo. | Alibaba Model Studio International list price. Tiered by input size: $0.30/$1.50 per 1M tokens for 0<Token≤32K, $0.50/$2.50 for 32K<Token≤128K, and $0.80/$4.00 for 128K<Token≤256K; the entry 0–32K tier is the headline shown here, the same basis used for every other tiered Alibaba row on this site. A long-context coding session bills at the higher tiers. No context-cache or batch rate is printed for this SKU, so cached input is left unset rather than assumed. Gateway resellers quote lower routed rates ($0.12/$0.80). This SKU's row carries no discount label, so the standard list rate is the one tracked here. |
