关于此模型
Gemini 3.8 Flash is Google's latest high-speed multimodal language model, built for real-time chat, coding, and agentic workloads. It accepts text and image inputs in a single request, supports a configurable system prompt, and offers adjustable reasoning depth for balancing latency against thoroughness. Its large context window and low latency make it a strong fit for production chat assistants, document summarization, and coding copilots that need fast, cheap responses at scale. For heavier reasoning workloads that need a larger context or deeper multi-step logic, see Gemini 3.1 Pro or Gemini 3 Pro.

常见问答
Gemini 3.8 Flash is Google's fast, cost-efficient multimodal language model for text and image understanding, tuned for real-time chat, summarization, and coding assistance.
Pricing is token-based at $2.50 per million input tokens and $12.50 per million output tokens, with a minimum charge of $0.0002 per call.
Yes. Pass an image_url alongside your prompt to ask questions about, summarize, or describe an image in the same request.
Yes, use the system_prompt field to steer the model's tone, persona, or response format across the conversation.
Use the streaming endpoint (/gemini-3-8-flash/stream) for interactive chat UIs where the user should see the response appear token-by-token. Use the async endpoint (/gemini-3-8-flash) for background jobs, batch processing, and workflow automation.
Both are fast multimodal chat models in the same family; Gemini 3.8 Flash is Google's newer release with improved reasoning and response quality at the same input/output field structure, so existing integrations built for 3.7 Flash migrate over with no code changes beyond the endpoint name.
