Gemini 3 Flash FAQ — Frequently Asked Questions

Is Gemini 3 Flash actually "Pro" level?

Yes, in reasoning capability. It scores 90.4% on GPQA Diamond (PhD-level reasoning), very close to Gemini 3 Pro's 91.9%. However, it's optimized for speed, not maximum depth.

How much faster is it than previous models?

Gemini 3 Flash is 3x faster than Gemini 2.5 Pro while outperforming it on 18 of 20 major benchmarks. It's designed for sub-second response times.

What are "Thinking Levels"?

A new API parameter that controls reasoning depth. Flash supports four levels: Minimal (instant), Low (quick queries), Medium (general use), and High (complex logic). This gives you explicit control over the speed vs. depth trade-off.

Does it support PDFs and video?

Yes, natively. It can process PDFs (rendered as images), up to 1 hour of video (45 min with audio), up to 8.4 hours of audio, and up to 900 images per prompt.

When should I NOT use Flash?

If your task requires deep multi-step reasoning, complex math proofs, or long research synthesis, consider Gemini 3 Pro. Or use the hybrid pattern: Flash for input processing, Pro for final reasoning.

What's the context window?

1 million input tokens and 65,536 output tokens. This is massive — enough for entire codebases, long videos, or hundreds of documents.
