Gemini 3.8 Flash is Google's most intelligent Flash model with significant gains from 3.7 Flash across software engineering, agentic tasks, and multi-step reasoning.
What the numbers mean
- Context window1,048,576 tokens
- How much the model can read in one request, counting your prompt, any files and the conversation so far. That is about 790,000 words, or 1,600 pages.
- Max output65,536 tokens
- The longest single reply it can write: about 49,000 words.
- Input price$0.82 per million tokens
- What you pay for everything the model reads. A 1,000-word prompt costs less than a cent.
- Output price$4.13 per million tokens
- What you pay for everything the model writes. Output usually costs more than input. A 500-word answer costs less than a cent.
- Modalitiestext, image, video, file, audio in, text out
- The kinds of content it accepts and the kinds it produces. A model that takes images in can read a screenshot; one that only puts text out cannot draw.
- Intelligence index30.8
- One score that combines several reasoning, knowledge and coding benchmarks. Higher is better. This model ranks 42 of the 96 scored models listed here.
Supported parameters
