gemini flash-lite latest is the cheapest model in Google's current Flash lineup, built for the kind of high-volume, low-margin-per-call workloads where price per token decides whether a feature ships at all. It shares the same 1,048,576-token context window and 65,536-token output ceiling as its Flash Latest sibling, and reasoning is switched on by default, but the price is a fraction of what Flash Latest charges — $0.25 per million input tokens and $1.50 per million output tokens, against $1.50 and $9.00 for the standard Flash tier.
Built for Volume, Not Headroom
This is the model for classification, extraction, routing, moderation, and other jobs that run millions of times a day rather than the model for a single hard reasoning problem. The same reasoning and function-calling support as Flash Latest is here, so it's not a stripped-down model in terms of capability shape — it's a cheaper one, tuned for scale rather than peak output quality on any single call.
The Cost Math
- Input: $0.25 per million tokens
- Output: $1.50 per million tokens
- Cached input: $0.025 per million tokens
- Context window: 1,048,576 tokens
- Max output: 65,536 tokens
At those rates, a call with 20,000 input tokens and a 500-token reply costs well under a cent — cheap enough that per-request cost mostly disappears as a design constraint, and the conversation shifts to throughput and latency instead. Cached input at $0.025 per million pushes repeat-context workloads, like the same system prompt or document reused across many calls, even lower.
What It Handles and What It Skips
Input modalities cover text, image, video, audio, and pdf, and vision is supported, so multimodal input isn't a Flash Latest-only feature. Output is text only. Function calling works, which matters for anything wiring this into an agent loop where the model needs to call tools rather than just answer.
Compared to Flash Latest
The capability score in this listing is 89.0 for both Flash Latest and Flash-Lite Latest, a signal that the gap between them is narrower than the price gap suggests — six times cheaper on input, six times cheaper on output, without a corresponding six-times drop in listed capability. That doesn't mean they're interchangeable on every task; it means the honest move is to test both on real prompts before assuming the pricier tier is necessary.
The Trade-off
The "Lite" name is accurate about cost, not about ability. What gets traded away by not defaulting to Flash Latest is headroom on the hardest prompts in a distribution, not baseline competence — most requests won't notice the difference, some will.
