OpenAI: GPT-5.2 Chat

GPT-5.2 Chat is OpenAI's text-generation model with a 128,000-token context window and up to 16,384 completion tokens per response. It accepts text, images, and file uploads as inputs and supports tool use, making it usable in agentic workflows. It does not include a built-in reasoning mode, and structured output support is unconfirmed based on available data. On pricing, it sits at $1.75 per million input tokens and $14.00 per million output tokens, which places it at a notable cost for output-heavy workloads. Prospective users should weigh that output rate carefully against alternatives with clearer benchmark records. No independent benchmark coverage currently exists for this model, so performance relative to competitors remains unverified. Teams already invested in the OpenAI ecosystem who need multimodal file and image handling alongside tool use may find it worth evaluating, but budget-sensitive users should wait for third-party evidence before committing.
