| Pricing Notes | DeepMind model page lists $1.50 input and $7.50 output per 1M tokens with no caching in the performance table. The ai.google.dev API docs were attempted through ScrapingBee and returned HTTP 400, so exact billing details beyond the official DeepMind price table were not used. | OpenAI promotional standard short-context pricing is $4 input, $0.40 cached input, $5 cache writes, and $20 output per 1M tokens through at least November 21, 2026. Standard long-context pricing is $8 input, $0.80 cached input, $10 cache writes, and $30 output; Batch, Flex, and Fast mode use separate rates. |
