| 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 Standard API, USD per million tokens for prompts with at most 272K input tokens: $2 input, $0.10 cached input, $2.50 cache writes, $10 output. Above 272K input, 2x input/cache and 1.5x output apply to the entire request. Fast mode is 2x Standard (not available with EU data residency); Batch and Flex are 50% below Standard. Regional processing adds 10% where available. Reasoning output tokens are billed as output. The maximum input limit is 922K tokens. |
