What is GPT-5.2?
GPT-5.2 is an OpenAI model for reasoning, coding, long documents and professional workflows. OpenAI's description emphasizes connecting information across a task and working through problems step by step.
UniRoute offers the gpt-5-2 chat model on this page. Ask it to explain code, analyze text or compare possible solutions, then use Responses or Chat Completions to bring the same model into your application.
OpenAI describes GPT-5.2 as an advance over GPT-5.1 in reasoning, coding and understanding long material. This workspace focuses on the callable GPT-5.2 model rather than treating every product name as a separate variant.
