Google Gemini Multimodal Tokenization (Text, Images, Audio & Video)
Google Gemini uses a SentencePiece tokenizer (~4 characters per token) for text and fixed token budgets for multimodal media inputs.
Total Tokens = TextTokens (~Chars ÷ 3.8) + (Images × 258) + (VideoSeconds × 263) + (AudioSeconds × 32)Standard images (≤384×384px) cost a flat 258 tokens; larger high-res images are tiled into 768×768px crops at 258 tokens per tile.
| Gemini Model / Modality | Input Rate / Token Rule | Cached Input (75% Off) | Output Rate / 1M | Max Context Window |
|---|---|---|---|---|
| Gemini 2.5 Pro (≤128K tier) | $1.25 / 1M tokens | $0.3125 / 1M tokens | $10.00 / 1M tokens | 2,000,000 tokens |
| Gemini 1.5 Pro (≤128K tier) | $1.25 / 1M tokens | $0.3125 / 1M tokens | $5.00 / 1M tokens | 2,000,000 tokens |
| Gemini 2.0 Flash | $0.10 / 1M tokens | $0.025 / 1M tokens | $0.40 / 1M tokens | 1,000,000 tokens |
| Multimodal Media Rates | Image: 258 tok | Video: 263 tok/s | Audio: 32 tok/sec | PDF Page: ~258 tok/page | Native Multimodal |

Frequently Asked Questions about Google Gemini Token & Multimodal Cost Calculator (2.5 Pro, 1.5 Pro & 2.0 Flash)
How many tokens does an image cost in Google Gemini?
In Google Gemini (1.5 Pro, 2.0 Flash, and 2.5 Pro), an image where both dimensions are ≤384px costs a flat **258 tokens**. Larger images are scaled and divided into 768×768px tiles, with each tile costing 258 tokens.
What happens when a Gemini Pro prompt exceeds 128,000 (or 200,000) tokens?
Google Gemini Pro uses two-tier context pricing: prompts under the 128K/200K threshold are billed at the base rate ($1.25/1M input), while prompts exceeding that threshold up to 2,000,000 tokens are billed at double the base rate ($2.50/1M input).
How many tokens is 1 minute of video or audio in Gemini?
Video is tokenized at approximately **263 tokens per second** (~15,780 tokens per minute of video), and audio is tokenized at **32 tokens per second** (~1,920 tokens per minute of audio).
Are my prompts or images uploaded to Google servers by this calculator?
