OpenAI: GPT-4

GPT-4 from OpenAI is an advanced AI model with an impressive context length of 8,191 tokens and supports text input and tool integration, making it versatile for complex tasks. However, it lacks explicit support for reasoning or structured output, limiting its use in scenarios requiring deep logical processing or formal outputs. Considering its blended benchmark score of 13.3 across two independent benchmarks, GPT-4 is a solid choice for users who can afford the premium price of $30 per million input tokens and $60 per million output tokens. Its performance may be particularly valuable in scenarios where text-based responses and tool integration are sufficient but where advanced reasoning or structured outputs are not required.
