Key features of Gemini 3.5 Flash API
Gemini 3.5 Flash focuses on speed, multimodal context, and agentic workflows rather than only single-turn chat.
01
Fast Flash model for agentic workflows
Google DeepMind describes Gemini 3.5 Flash as the next iteration of the Gemini 3 Flash reasoning foundation. It is well-suited for coding tasks, agentic workflows, and long-running enterprise processes that need lower latency than heavier models.
- Preview Flash model
- Optimized for agents and coding
- Good speed-to-quality profile
02
1M context with multimodal input
The official model card lists text, image, audio, and video inputs with a token context window of up to 1M. Use it for large document packets, video or audio analysis, and multimodal product workflows.
- Text, image, audio, video, and PDF inputs
- Up to 1M token context window
- 64K token text output
03
Thinking levels for quality, cost, and latency
Gemini 3.5 Flash uses thinking levels to control the mix of quality, cost, and latency. That makes it useful for systems that need fast answers most of the time and deeper reasoning only on harder turns.
- Control reasoning depth
- Tune latency and spend
- Use deeper thinking for harder tasks
04
Gemini Native and OpenAI-compatible access
PoYo supports Gemini 3.5 Flash through the existing Gemini Native Format endpoint for full Gemini-style payloads, plus /v1/chat/completions for teams that prefer OpenAI-compatible chat clients.
- /v1/chat/completions for compatibility
- /v1beta/models for Gemini Native Format
- One API key for both paths
What can you build with Gemini 3.5 Flash API?
01
Fast AI agents
Build agents that plan, call tools, and iterate quickly while staying cheaper than heavier frontier reasoning models.
02
Coding assistants
Use Gemini 3.5 Flash for repo triage, debugging plans, code explanations, and agentic coding tasks that benefit from fast model turns.
03
Multimodal analysis
Process text, images, audio, video, and PDFs in applications that need broader context than text-only chat.
04
Enterprise knowledge workflows
Summarize long packets, reason over internal documents, and automate repeated knowledge-work steps with 1M context.
Gemini 3.5 Flash vs GPT-5.5 and Claude Opus 4.7
Compare Gemini 3.5 Flash with two premium reasoning models: GPT-5.5 for OpenAI-style coding agents and Responses API workflows, and Claude Opus 4.7 for long-context hybrid reasoning, coding, and computer-use tasks.
