frequently asked
What is Gemini 3.5 Flash best for?
Gemini 3.5 Flash is Google's high-efficiency multimodal model, bringing near-Pro level coding and reasoning at Flash-tier cost and speed. It is highly optimized for coding proficiency and parallel agentic execution loops, supporting text, image, video, audio, and PDF inputs. Defaults to medium thinking effort for faster and more cost-efficient responses, with full support for thinking levels (minimal, low, medium, high) for fine-grained cost/performance trade-offs.
How much does Gemini 3.5 Flash cost?
$1.50/M input and $9/M output, cache reads $0.15/M. In an agent loop most input is cache-read, so the effective input rate is about $0.56/M.Which plan do I need?
Available on Pro and above.
How do I switch to it?
