Benchmark Caveat

Provider documentation and provider-published capability notes are directional, not universal rankings. Real results depend on prompts, tools, latency targets, pricing tier, safety filters, context length, and workload mix.

Best for

Evaluate for bounded extraction, translation and classification tasks; these are vendor-documented use cases, not measured Kingy recommendations.

Skip if

Skip the retired -preview identifier. Do not choose this model for native image/audio generation, computer use or the Live API; Google lists those capabilities as unsupported.

Strengths

Documented support for function calling, structured outputs and thinking. Input token limit: 1,048,576; output token limit: 65,536.

Weaknesses

No Kingy workload benchmark is published here. Account quotas, region eligibility, latency and task accuracy still need checks for your deployment.

Agent suitability

Function calling and structured output are documented. Validate tool permissions, schema conformance and failure handling in your own integration.

Kingy AI take

The stable model remains documented as available. Compare it with Google’s listed replacement, Gemini 3.5 Flash-Lite, on your workload; the retired preview is a different identifier.

Plan, price and billing scope

USD API: US$0.25 input / US$1.50 output per 1M tokens. Google’s stable Gemini 3.1 Flash-Lite accepts text, images, video, audio and PDFs and produces text. This is a documentation review, not a Kingy performance test. Prices use the currency and billing term stated here. Where a numeric rate, region or current entitlement could not be verified, it remains explicit; no checkout was completed.

Limits that affect the decision

Text, image and video input; audio input is US$0.50 per million tokens. Thinking output is billable where supported; grounding, caching and other tiers are separate.

Sources and buying-review date

Buying review completed October 23, 2026. This is a source-based buying assessment. No paid product test, new generation, checkout or performance benchmark was performed. Vendor descriptions and historical examples remain distinct from independently measured results. The date does not renew the broader canonical fact ledger.

Earlier profile, sources and dates

This older record retains its original scope. Current buying qualifications above take precedence where terms have changed.

This record covers the stable API identifier gemini-3.1-flash-lite. It is distinct from gemini-3.1-flash-lite-preview, which Google marks as shut down.

Documentation reviewed September 14, 2026. Google’s deprecation schedule gives May 7, 2027 as the stable model’s earliest possible retirement date and lists Gemini 3.5 Flash-Lite as its replacement. That date is not a guaranteed exact shutdown time.

Documented API scope

The model documentation lists text, image, video, audio and PDF input; text output; an input limit of 1,048,576 tokens and an output limit of 65,536 tokens. Function calling, structured output and thinking are supported. Native image/audio generation, computer use and the Live API are not.

Price scope

Google’s Standard paid Gemini Developer API rates, in USD per million tokens, are $0.25 for text/image/video input, $0.50 for audio input and $1.50 for output including thinking. These rates exclude caching, grounding and other tool charges. Batch, Flex, Priority and free-tier rules differ; account and region eligibility must be checked separately.

Correction history

The September 14, 2026 correction separates the stable model from its retired preview across the profile and canonical fact records. It removes the prior instruction to avoid the stable model solely because the preview shut down. No API generation, latency or quality test was run for this correction. The original publication date and URL are preserved.
