Gemini 3.5 Flash

Overview

Gemini 3.5 Flash is a Flash-tier model in the Gemini 3 family. It is designed for low-latency, cost-efficient workloads that still require strong reasoning, coding support, and multimodal understanding.

On B.AI, use the model ID gemini-3.5-flash.

Key Features

  • Agentic Execution: Suitable for sub-agent deployment, multi-step workflows, and rapid agentic loops at scale.
  • Coding Support: Optimized for iterative coding cycles, rapid exploration, and prototyping where fast turnaround matters.
  • Configurable Thinking Levels: Supports minimal, low, medium, and high thinking levels, with medium as the default.
  • Combined Tool Use: Supports function calling, code execution, Google Search grounding, URL context, and structured outputs.

Best Use Cases

  • Agentic Workflows at Scale: A strong fit for production agent systems that need fast, repeated tool calls and sustained task progress.
  • Rapid Coding Iterations: Useful for developer tools, code generation pipelines, debugging assistance, and interactive prototyping.
  • Cost-Efficient Intelligence: Suitable for high-volume production workloads that need a balance of speed, capability, and cost.
