GPT-5.2 Chat API on ModelFold
GPT-5.2 Chat (also called Instant) is the fast, lightweight member of the GPT-5.2 family, optimized for low-latency chat. It uses adaptive reasoning and only thinks when a question calls for it. Try GPT-5.2 Chat in the ModelFold Playground, then call it from your own code through an OpenAI-compatible chat completions API.
What Is the GPT-5.2 Chat API
GPT-5.2 Chat at a glance
GPT-5.2 Chat is a chat model from OpenAI. It accepts text, images and files (such as PDF) as input and returns text, with a context window of up to 128K tokens.
Use it without hosting anything
On ModelFold you call GPT-5.2 Chat with a single API key — no model weights to download and no inference servers to run. The same key also works for the other chat, image, video and audio models on ModelFold.
Core Capabilities of GPT-5.2 Chat
Up to 128K tokens of context
Keep long conversations, large documents and sizeable code in a single request, so the model can reason over the full material instead of fragments.
Understands images and files (such as PDF)
Besides text, GPT-5.2 Chat accepts images and files (such as PDF) as input, so a single request can combine instructions with visual or other media.
Function calling
GPT-5.2 Chat supports tool (function) calling: describe your functions in the request and the model returns structured calls your code can run — the basis for agents and integrations.
Structured outputs
Ask for JSON that follows a schema (response_format), which makes extraction, classification and system integrations more reliable.
