OpenAI: GPT-4o
Analysis Summary
OpenAI's GPT-4o is a multimodal model released in May 2024. The supplied data lists a 128K context window, image and file input, vision, tool use, and function calling. Its measured intelligence index is 8.4, with additional reasoning and coding-related benchmarks, but these results sit well below leading models in the current landscape. Its listed pricing is lower than the dated GPT-4o entry in this batch.
The combination of multimodal input and tool interfaces suits document processing, visual tasks, and structured assistant workflows. It is usable for client content and moderate automation when teams evaluate outputs and maintain fallbacks. The benchmark profile does not support choosing it for the hardest reasoning or coding tasks over newer high-capability models. Consider it for existing integrations or workflows where its features and pricing are competitive, and route routine volume to lower-cost options where quality holds.
