Google Gemini 3.8 Flash is Google's newest Flash-tier workhorse model (released September 2026), succeeding Gemini 3.7 Flash with significant improvements in software engineering, agentic tasks, and multi-step reasoning in specialized domains. On hard problems it works harder, running extra reasoning steps and calling tools iteratively, and often approaches the performance of higher-cost frontier models while keeping Flash speed and cost efficiency. It accepts text, images, video, audio, and PDF input, supports very long context, and offers a thinking (reasoning) mode with selectable low/medium/high effort (default medium). Type your request directly, attach images, PDFs, or documents for the model to read, or enable web search for up-to-date answers. Good fit for coding and debugging, multi-step automation, summarization, translation, and mid-to-heavy data work. Use Gemini 3.7 Flash when you want to minimize token usage, or Gemini 3.1 Pro for top-tier reasoning. If you need to search the web for information, please turn on the "Web Search" switch. Maximum context window (input and output combined): about 1,048,576 tokens. Maximum output per reply: about 65,536 tokens (model reasoning, if any, counts toward this limit). Maximum total upload size per request: 256MB (all files and message content combined). Accepted document formats: pdf, docx, xlsx, pptx, txt, csv (file content is provided to the model as extracted text). Accepted image formats: heic, heif, jpeg, jpg, png, webp. Maximum number of images: 3600. Maximum size per image: 14MB. Maximum total image size per message: 14MB (text and history share the same request size limit; uploads close to the limit may still be rejected). Image dimensions: at least 200 pixels per side. Maximum image resolution: 36,000,000 pixels in total. Output content formats: Text This module supports continuous conversations. AI can make mistakes. Please verify important information.
