What the numbers mean
- Context window65,537 tokens
- How much the model can read in one request, counting your prompt, any files and the conversation so far. That is about 49,000 words, or 98 pages.
- Max output58,983 tokens
- The longest single reply it can write: about 44,000 words.
- Input price$0.19 per million tokens
- What you pay for everything the model reads. A 1,000-word prompt costs less than a cent.
- Output priceFree
- What you pay for everything the model writes. Output usually costs more than input. A 500-word answer costs nothing.
- Modalitiestext, image in, decisions 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.
