OpenAI GPT Latest

OpenAI GPT Latest is a paid model from OpenAI that accepts text, images, and files as input. It offers a context window of roughly 1 million tokens and can produce up to 128,000 tokens per response. The model supports tool use and reasoning, which makes it applicable to agentic workflows and multi-step tasks. Structured output support is unconfirmed based on available data. At $5.00 per million input tokens and $30.00 per million output tokens, this sits at the higher end of typical API pricing, and there is currently no independent benchmark coverage to validate where its performance lands against alternatives. Buyers who need large-context document processing, tool-calling pipelines, or multimodal input in a single model may want to shortlist it, but the absence of benchmark data means performance claims rest entirely on OpenAI's own materials rather than independent evaluation.
