OpenAI: GPT-4o (2024-11-20)

GPT-4o (2024-11-20) is a multimodal model from OpenAI that accepts text, images, and files as input, with a 128,000-token context window and a maximum of 16,384 output tokens per completion. It supports tool use, making it suitable for agentic workflows and function-calling tasks. Reasoning mode and structured output are not confirmed in the available specifications. At $2.50 per million input tokens and $10.00 per million output tokens, this sits in the mid-to-upper tier of general-purpose model pricing. Its blended benchmark score of 17.3 is drawn from only one benchmark (aider_polyglot at 18.2), so broad performance comparisons should be treated with caution. Teams that need reliable multimodal input handling and tool integration, and are already within the OpenAI ecosystem, are the most natural fit; buyers prioritizing cost efficiency or well-rounded benchmark coverage may want to weigh alternatives before committing.
