OpenAI: GPT-5.2 (batch)
- by openai
- openai/gpt-5.2:batch
GPT-5.2 is the latest frontier-grade model in the GPT-5 series, offering stronger agentic and long context perfomance compared to GPT-5.1. It uses adaptive reasoning to allocate computation dynamically, responding quickly...
What the numbers mean
- Context window400,000 tokens
- How much the model can read in one request, counting your prompt, any files and the conversation so far. That is about 300,000 words, or 600 pages.
- Max output128,000 tokens
- The longest single reply it can write: about 96,000 words.
- Input price$0.88 per million tokens
- What you pay for everything the model reads. A 1,000-word prompt costs less than a cent.
- Output price$7 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.
- Modalitiesfile, image, text 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.
Supported parameters
The settings you can pass with a request. A model that lists tools can call functions; one that lists structured_outputs can be held to a JSON schema.
