Gemini 3.5 Flash Lite FAQ

Answers to common questions about the Gemini 3.5 Flash Lite model features, pricing, and technical performance.

How fast is Gemini 3.5 Flash Lite?

Gemini 3.5 Flash Lite is built for speed, offering sub-100ms Time To First Token. It is roughly 30-40% faster than the standard Flash model for text prompts, making it ideal for real-time apps.

What is the context window for this Gemini model?

This model supports a massive 1.04 million token context window. This allows you to process entire technical manuals, long video files, or large codebases in a single request at a very low cost.

Is Gemini 3.5 Flash Lite multimodal?

Yes, it is natively multimodal. It can process images, audio, video (up to 1 hour), and PDFs. It performs exceptionally well in visual tasks, scoring 68.2% on the MMMU benchmark.

How does Gemini 3.5 Flash Lite pricing work?

It is the most cost-effective model in the Gemini 3.5 family, priced at $0.075 per 1M input tokens. This is approximately 50% cheaper than the standard Gemini 3.5 Flash model.

Can Gemini 3.5 Flash Lite handle JSON?

Absolutely. It features an optimized internal head for JSON schema adherence, achieving a 98% success rate on complex nested extraction tasks, which is perfect for data pipelines.

When should I use Gemini 3.5 Pro instead?

While the Lite version is great for speed, choose Gemini 3.5 Pro for tasks requiring complex logical reasoning, advanced math, or deep architectural understanding of codebases.
