OpenAI: GPT-5.2 Chat

GPT-5.2 Chat is OpenAI's multimodal text model, accepting text, images, and files as input. It offers a 128,000-token context window with a 16,384-token output ceiling, and it supports tool use. Reasoning mode and structured output are not documented for this model based on available specifications. On pricing, input costs $1.75 per million tokens and output costs $14.00 per million tokens; the output rate in particular is on the higher end compared with many current alternatives. Benchmark coverage is absent at this time, so there is no independent performance data to anchor a quality assessment. Buyers who already rely on the OpenAI ecosystem and need file and image handling alongside tool use may find it worth evaluating, but those prioritizing verified benchmark performance or lower output costs should compare carefully against models with established coverage before committing.
