What it costs per month
Token prices applied to three workload shapes. Input-heavy and output-heavy workloads rank models very differently.
In-app chat assistant
A support or help assistant handling a few thousand conversations a month, with short prompts and short answers.
$4.00/mo
- 20M input tokens$2.00
- 5M output tokens$2.00
- If fully cached$2.50
RAG over documents
Retrieval-augmented answering where each request stuffs several retrieved passages into the prompt, so input dominates.
$36/mo
- 300M input tokens$30
- 15M output tokens$6.00
- If fully cached$14
Coding agent
An agentic loop that reads files and writes patches, generating heavy output and re-sending large context on every turn.
$80/mo
- 400M input tokens$40
- 100M output tokens$40
- If fully cached$50

Questions about pricing
- How much does the Gemini 2.5 Flash-Lite API cost in 2026?
- $0.100 per million input tokens and $0.400 per million output tokens, from Google's published pricing. The table above converts that into a monthly figure for three common workloads.
- What is the Gemini 2.5 Flash-Lite context window?
- 1M tokens, with up to 66K tokens of output per request. Filling the window costs whatever that many input tokens cost — at $0.100 per million, a single full-context request runs about $0.10.
- Does Gemini 2.5 Flash-Lite support prompt caching?
- Yes. Cached input is billed at $0.025 per million tokens, roughly 4× cheaper than uncached input. For an agent that resends the same system prompt and file context on every turn, that discount usually matters more than the headline rate does.
- Is Gemini 2.5 Flash-Lite cheaper than the alternatives?
- On a blended 3:1 input-to-output basis it works out at $0.175 per million tokens. The comparison table below ranks it against the other small / fast models in the dataset, and the head-to-head pages model both against identical workloads.
