OpenAI: GPT-5 Codex (batch)

The OpenAI GPT-5 Codex (batch) is designed for handling both text and image inputs with a context length of 400,000 tokens and supports reasoning, making it suitable for complex tasks that require understanding across large volumes of data or visual content. It can process multi-modal inputs and engage in detailed reasoning but does not offer structured output capabilities. Given its high price point at $5.00 per million output tokens and $0.625 per million input tokens, the GPT-5 Codex is best suited for organizations willing to invest in premium AI solutions that can handle extensive reasoning tasks with text and images. However, due to a lack of independent benchmark coverage, its performance relative to other models remains unproven, making it essential to carefully consider alternative options before shortlisting this model.
