Gemini 2.5 Flash Lite API Pricing: Extreme Low-Cost High-Speed Inference
Comprehensive Gemini 2.5 Flash Lite API pricing analysis ($0.10/M input, $0.40/M output), sub-80ms first-token latency, classification efficiency, and upgrade comparisons.
How much does Gemini 2.5 Flash Lite cost per million tokens?
Gemini 2.5 Flash Lite costs $0.10 per million input tokens and $0.40 per million output tokens ($0.175/M blended at 3:1). Designed for ultra-high-volume micro-tasks, classification, and real-time voice latency. Verified 2026-09-08.
How much does Gemini 2.5 Flash Lite cost per 1,000 requests?
Computed from generated token pricing. Each row assumes the listed input and output tokens per request; this model has no measured verbosity factor, so the unadjusted output estimate is shown.
| Request shape | Input tokens | Output tokens | Cost / 1,000 requests |
|---|---|---|---|
| Short | 100 | 50 | $0.0300 |
| Medium | 1,000 | 500 | $0.3000 |
| Long | 4,000 | 2,000 | $1.2000 |
Formula: ((input price × input tokens) + (output price × output tokens × verbosity factor)) ÷ 1,000,000 × 1,000. Assumptions: short 100/50, medium 1,000/500, long 4,000/2,000 input/output tokens per request. Unadjusted — no measured verbosity factor is available.
Migration delta, task-ranking cross-check, and lifecycle ledger for Gemini 2.5 Flash Lite
Successor rate delta
| Rate | Gemini 2.5 Flash Lite | Gemini 3.5 Flash Lite | Delta ($ / %) |
|---|---|---|---|
| Input $/M | $0.10 | $0.30 | $0.20 (200.0%) |
| Output $/M | $0.40 | $2.50 | $2.10 (525.0%) |
Delta = successor rate − Gemini 2.5 Flash Lite rate, both taken from the current dated pricing registry. Cache, batch, and context-tier pricing are not substituted across models; each figure is model-specific or marked Unavailable.
Where Gemini 2.5 Flash Lite still ranks across every task page
| Task | Rank / status | Task-weighted $/M | Pick status |
