gemini-2.5-flashAt Gemini 2.5 Flash's rates ($0.3 per 1M input tokens, $2.5 per 1M output), a call with 1,000 input and 500 output tokens costs $0.00155. At 10,000 requests a month, that workload runs $15.50. A heavier call — a 100,000-token prompt returning 2,000 tokens — costs $0.035.
Within Google Gemini's lineup, Gemini 2.5 Flash runs 5.2× the per-call cost of Gemini 2.5 Flash-Lite and 5.2× less than Gemini 3.1 Pro at this workload. It is priced identically to Gemini 3.5 Flash-Lite ($0.3 in / $2.5 out per 1M tokens) — for this calculator the two differ only in the model itself, not the bill.
Cache-read input is billed at $0.03 per 1M tokens — 90% below the standard input rate, so a long system prompt reused across calls mostly bills at the discounted rate.
Gemini 2.5 Flash's context window is 1,000,000 tokens.

Token counter
Token counts are exact for OpenAI models (tiktoken o200k_base, run in your browser). For other providers the count is an estimate — notably Claude Opus 4.7+/Sonnet 5 and similar newer models use a tokenizer that produces roughly 30% more tokens for the same text.
