About the model

This description covers the model’s capabilities. Available in Ailoot inputs, outputs and options are listed for the selected method below.

Gemini 3.5 Flash-Lite is Google’s execution-focused multimodal text profile for repeated data work and focused subagent tasks. It builds on Gemini 3.1 Flash-Lite, improving document understanding, tool reliability and multi-turn instruction following. It accepts text, images, audio, video and PDF and returns text. A useful result is one extracted record, a classification, a short translation or a bounded tool-assisted analysis within a larger task.

For document parsing, define the fields that matter and the evidence each field must retain. Provide the relevant pages and specify how to represent absent or ambiguous information. For support-message extraction, extract a product code, mentioned issue and supporting sentence from a support message, keeping the message identifier in the answer. A document with multiple candidates for a field should not silently collapse them into one guessed value. Structured JSON can make the result usable for later processing when its schema matches the actual task.

The documented thinking levels are minimal, low, medium and high, with minimal as the default. The maker recommends it for high-volume extraction, routing and classification, while medium or high is appropriate for autonomous subagent work involving tool calls, code execution or several reasoning steps. The guide specifically advises increasing effort for those longer tasks to avoid premature tool termination. A one-field extraction and a document comparison with exceptions therefore benefit from different effort choices. Minimal is a supported setting of this edition rather than a general setting to transfer to every Flash model.

A focused subagent brief should contain one job, its source material, permitted tools and the required final form. For example, it can examine a table for a stated rule and return the affected rows with the relevant values. The maker also highlights tabular-data processing and frontend JavaScript work assisted by lightweight code execution. The surrounding application remains responsible for running a requested function and returning the real result. Keep a finished result distinguishable from an unexecuted suggestion or an unresolved input question.

The exact 3.5 Flash-Lite page lists function calling, code execution, file search, search grounding, Maps grounding and URL context, with Computer Use marked as preview. Structured output and thinking are supported. For a multi-turn persona or task, retain the actual instructions and tool observations so later replies follow the same assignment. The developer guide highlights stronger persona persistence than 3.1 Flash-Lite. Use a concise role and output contract rather than redefining the objective at every follow-up.

The guide also deprecates legacy sampling settings and prefilled final model turns for this edition. Control a bounded answer with explicit instructions or a schema rather than trying to start the answer inside a synthetic model-role turn. Preserve the Gemini 3 thought-signature context where the interface requires it, and match function results to their calls. These preparation rules support a continuation that still has the evidence needed to complete the same job.

The native card lists up to 1M context and 64K text output; the exact API page specifies 1,048,576 input tokens and 65,536 output tokens. Instructions, records, history and media all contribute to input preparation. Caching, batch, Flex and Priority options are listed for the producer profile. For repeated requests, use stable identifiers and a compact consistent answer format so each extraction can be compared with its source. Audio, image or video input produces a text interpretation or transcript in this profile, rather than generated speech or artwork.

Possible limitations include hallucinations and occasional delays or timeouts. Its knowledge cutoff is March 2026, with some domains limited to January 2025. Source-dependent extraction should return what the supplied material supports; current-fact questions need current evidence. Compared with 3.1 Flash-Lite, this profile adds the documented execution and computer-use capabilities, while 3.6 Flash emphasizes more complex coding and spatial work. Review extracted fields, tool results and retained instructions before incorporating the answer into a larger workflow.

Practical task

### Extract a support message record

Technical example in English

```
Extract a support message record

Extract fields from message S-91: "The pump P-28 stopped after ten minutes. I bought two, but only one has this issue. Please arrange a replacement." Return message ID, product code, issue, purchased quantity and affected quantity in a small table. Include the exact supporting phrase for each extracted value.
```

#### Expected result

```
A field/value/evidence table retaining S-91 and separating purchased from affected quantity.
```

#### Check the result

```
Check that two purchased pumps do not become two defective pumps.
```

Output

$0.0025 */ 1K*

Cache read

≈$0.00003 */ 1K*

Ailoot reserves an estimated amount before a request. After the result, it settles the final charge from measured usage. Streaming settlement uses the final usage record. [How reservation and settlement work →](https://ailoot.ai/docs/en/billing/reserve/)

#### Reference tariff details

Model-level reference schedules do not change method selection, quotes or charges. Active charges use the selected Ailoot method rates.

Ailoot reserves an estimated amount before a request. After the result, it settles the final charge from measured usage. Streaming settlement uses the final usage record. [How reservation and settlement work →](https://ailoot.ai/docs/en/billing/reserve/)

#### Reference tariff details

Model-level reference schedules do not change method selection, quotes or charges. Active charges use the selected Ailoot method rates.

#### Ailoot method rates

Input

$0.0003 */ 1K*

Output

$0.0025 */ 1K*

Cache read

≈$0.00003 */ 1K*

Ailoot reserves an estimated amount before a request. After the result, it settles the final charge from measured usage. Streaming settlement uses the final usage record. [How reservation and settlement work →](https://ailoot.ai/docs/en/billing/reserve/)

#### Reference tariff details

Model-level reference schedules do not change method selection, quotes or charges. Active charges use the selected Ailoot method rates.
