OpenAI: GPT-5.2
Analysis Summary
GPT-5.2 is OpenAI's benchmarked flagship at this tier, with an intelligence index of 51.3 and a coding index of 48.7, placing it firmly in the top tier of the broader model landscape. Its agentic index of 65.9 and tau2 score of 0.848 confirm strong multi-step tool use reliability, and the 400K context window makes it one of the most capable models for long-document and large-codebase workflows.
For businesses, this model covers a wide range of high-value tasks: autonomous coding agents, complex document analysis, structured content generation, and customer-facing reasoning. Vision and function calling support mean teams can consolidate multiple workflows on a single model. Instruction following (ifbench 0.754) and long-context reasoning (lcr 0.727) are both strong, supporting reliable client-facing output.
At $1.75 input and $14 output per 1M tokens, it is priced for high-value use rather than bulk traffic. Teams should pair it with a cheaper model for routine calls and reserve GPT-5.2 for tasks where depth and accuracy justify the cost.
