Gemini 2.5 Flash Lite API

Billed from your GPUniq balance as you use it — no subscription, no monthly minimum, no per-seat fee. Prices refresh from the live catalog hourly.

API identifier

gemini-2.5-flash-lite

Pass this exact string as the "model" field of your request.

Type

Chat & text

Served by Google.

Context window

1,048,576 tokens

About roughly 786,432 words — about 1,573 printed pages. Prompt, conversation history and attachments all count against it.

Max output

65,535 tokens

Ceiling for a single reply. Set max_tokens below it to cap cost per request.

Accepts

Text, Images, Files (PDF and similar documents), Audio, Video

What you can put in the request body besides plain text.

Returns

Text

Measured speed

≈10 tokens/sec

Rolling average of real GPUniq traffic. This sample comes from non-streaming requests, so it includes the wait before the first token.

Tokenizer

Gemini

Determines how your text splits into billable tokens.

Available since

2025-07-22

Knowledge cutoff

2025-01-31

The model has no built-in knowledge of events after this date.

Upstream moderation

No

No vendor-side safety filter is applied on top of the model.

• Function calling: supported

  Send tool definitions, get back the call the model wants made.

• Structured outputs: supported

  Replies constrained to your JSON Schema.

• Vision input: supported

  Accepts images in the message content.

• Extended reasoning: supported

  Thinks before answering; thinking tokens bill as output.

Create a key on /chat and send it as a bearer token. The same key works across every model in the catalog, so switching models means changing one string.

include_reasoning

Returns the reasoning trace alongside the answer instead of hiding it.

max_tokens

Hard cap on the reply length. Also your cost ceiling per request, since output is the expensive half of the bill.

reasoning

Extended thinking. The model works through the problem before answering; the thinking tokens are billed as output.

response_format

Selects the response shape — plain text or JSON. The weaker cousin of structured outputs: it enforces valid JSON, not your particular schema.

seed

Asks for repeatable sampling. Best effort on every vendor — it makes runs similar, it does not make them identical.

stop

Stop sequences that cut generation as soon as they appear.

structured_outputs

Schema-constrained decoding: the reply is guaranteed to parse against the JSON Schema you supply, so no retry loop around JSON.parse.

temperature

Randomness. Near 0 for extraction and classification, higher for drafting and ideation.

tool_choice

Forces or forbids a tool call for one request — useful when you want a guaranteed structured answer instead of prose.

tools

Function calling. You describe callable functions in JSON Schema and the model replies with the call it wants made, which is what agent frameworks are built on.

top_p

Nucleus sampling — an alternative to temperature. Tune one or the other, not both.
