OpenAI: GPT-5.2

GPT-5.2 is a closed, paid model from OpenAI that accepts text, images, and file uploads, making it usable for document-heavy and multimodal workflows. It supports a 400,000-token context window and up to 128,000 output tokens per completion, which suits tasks requiring long inputs or extended generations. Tool use and reasoning are both supported, giving it flexibility for agentic and multi-step tasks. On price, it sits at $1.75 per million input tokens and $14.00 per million output tokens, so output costs are relatively steep compared to many alternatives. Its blended benchmark score of 82.1 covers only two benchmarks, meaning that figure carries limited confidence and should not be treated as a definitive performance signal. Teams with genuinely long-context needs or multimodal requirements may find it worth shortlisting, but cost-sensitive users or those wanting broader benchmark validation should compare it carefully against lower-output-cost models before committing.
