Gemini 3.5 Flash is Google’s most intelligent Flash model, available through Anyfast via the native Gemini API. It delivers state-of-the-art performance for agentic execution, coding, and long-running tasks.

​
Key capabilities

  • 1M token context window — Handle massive documents and conversations, with up to 65,000 output tokens
  • Thinking levels — Control reasoning depth with minimal, low, medium (default), and high
  • Thought preservation — Model automatically retains intermediate reasoning across multi-turn conversations
  • Agentic execution — Optimized for multi-agent deployment, problem-solving, and large-scale agentic loops
  • Coding — Excels at iterative coding cycles, rapid exploration, and prototyping
  • GA release — Stable model ready for production at scale
