OpenAI: GPT-5.2 Chat

The OpenAI GPT-5.2 Chat is designed for handling text, file, and image inputs with a context length of 128,000 tokens and can generate up to 32,000 completion tokens. It supports tools but lacks reasoning and structured output capabilities. At a cost of $1.75 per million input tokens and $14.0 per million output tokens, it is suited for projects requiring extensive text processing or multimodal data handling; however, its lack of benchmark coverage makes performance comparisons challenging. Given the absence of independent benchmarks, GPT-5.2 Chat stands out primarily for its high context and token limits, making it a strong choice for complex text-based applications where raw input volume is crucial. Despite its premium pricing, it offers flexibility in handling various data types, which could be beneficial for specific use cases.
