OpenAI: GPT-4o (2024-05-13)

GPT-4o from OpenAI is an advanced AI model with a context length of 128,000 tokens and support for text, image, and file inputs. It can handle multiple modalities but lacks reasoning capabilities and structured output formats; however, it does integrate tools. While its benchmark scores are robust, coming in at 14.2 on the AI Index and a strong 40.0 on coding tasks, GPT-4o is not free, with pricing at $5.0 per million input tokens and $15.0 for outputs. Given these costs and its blended benchmark score of 23.3 across two independent benchmarks, it may be more suitable for projects requiring specific modalities but where the cost is justified by the need for extensive text or coding tasks.
