Analysis Summary

OpenAI GPT-5.2 is a mid-generation model from OpenAI with an intelligence index of 26, a livecodebench score of 0.669, and an agentic index of 39.2. It supports vision, tool use, and function calling across a 400K context window, making it one of the more capable multimodal models in its tier. Instruction-following and long-context reasoning scores are above average for its intelligence band.

For businesses, GPT-5.2 suits software engineering assistance, document analysis, agentic pipelines, and client-facing content workflows. The 400K context window is a practical advantage for codebase review or long-contract analysis. Its main limitation is cost: at $1.75 input and $14.00 output per million tokens, it is expensive relative to models with comparable intelligence scores.

Teams that need reliable multimodal capability with strong tool use and are willing to pay a premium for OpenAI's ecosystem and reliability will find GPT-5.2 a capable choice. For cost-sensitive workloads, pairing it with a cheaper model for routine calls is advisable.
