# Gemini 2.5 Flash

Google · released 2025-06-17 · proprietary

 $0.850 per million tokens, balanced Balanced Summarise Chat Code gen Agentic

## No independent quality score.

No benchmark we track has measured this model. That is not the same as measuring it and finding it wanting — we simply cannot rank it, so we do not.

## Our take

 editorial — not a measurement

The previous-generation cheap Gemini at $0.30/$2.50, still worth knowing because of a pricing quirk the newer models share: audio input is billed on a separate, much higher scale — $1.00/MTok versus $0.30 for text. Any cost model that treats 'input tokens' as one number will understate audio workloads by more than 3x. Otherwise superseded by the 3.x Flash line on capability.

### Strengths

 - $0.30/$2.50 with a 1M context window
- Mature and widely deployed
- Full multimodal input

### Weaknesses

 - Audio input billed at $1.00/MTok, over 3x the text rate
- Superseded by 3.5 and 3.7 Flash on capability
- Caching storage fees apply

### Reach for it when

 - Existing deployments not yet migrated
- Text-only high-volume work at low cost

### Avoid it if

 - Audio-heavy pipelines — check the separate rate first
- You are starting fresh; use 3.7 Flash

### Every price dimension

| Input | $0.300 /M |
| --- | --- |
| Output | $2.50 /M |
| Cached input | $0.030 /M |
| Cache write | $0.083 /M |
| Reasoning | $2.50 /M |
| Web search | $0.014 /call |
| Batch discount | 50% |

**Reasoning tokens are billed separately** at $2.50/M, on top of output. On a reasoning-heavy workload this can be 40% of the bill and it does not appear in the advertised price.

### Independent scores

Sources are listed separately rather than averaged. Across the 62 models both have scored they correlate at r = 0.806 — close agreement overall, but four models rank very differently between them, and a blended score would hide exactly those.

### Capability

| Context window | 1.0M |

| Max output | 66K |
| Input modes | file, image, text, audio, video |
