Gemini 3 Flash offers strong coding capability at Flash-tier pricing. This guide explains how to use it and when it delivers the most value.

Quick Answer

Gemini 3 Flash balances coding quality and cost. Use it for completions, chat, and everyday coding when you want good output without Pro-tier pricing. Available in Cursor, Windsurf, Continue, Aider, and via Gemini API.

Why Flash for Coding

Benefit Details
Cost Lower per-token than Pro
Speed Often faster responses
Quality Strong for routine coding tasks
Volume Good for high-usage workflows

When to Use Flash vs Pro

Task Prefer
Inline completions Flash
Chat, small edits Flash
Large refactors, complex reasoning Pro
Long documents, 1M context Pro (if supported)

How to Use Gemini 3 Flash

In Cursor

  • Open model picker; select Gemini 3 Flash if available.
  • Use for Composer, Agent, or completions.
  • BYO API key may be required for some plans.

In Continue / Aider

  • Add Google as a provider.
  • Set model to gemini-3-flash or equivalent.
  • Configure API key in Continue config or env.

Via API

  • Use Gemini API with Flash model name.
  • See Gemini API for docs.

Google-First Stack

If you use Google Cloud, Vertex AI, or Gemini elsewhere, Flash fits well for a consistent, cost-effective coding layer.
