|---|---|---|
| Standard | $2 | $10 |

Context
Context window
Gemini 4 Argon accepts up to 1,048,576 tokens per request, roughly 786,432 English words or 1,573 pages. That budget is shared between your prompt and the reply, and a single reply is capped at 65,536 tokens.
Filling the whole window with one prompt costs about $2.10 at list price, so for repeated long-document work, retrieval (sending only the relevant parts) or prompt caching is usually much cheaper.
