GPT-4o (2024-11-20)

A multimodal large language model that processes text and images, with native support for structured outputs via JSON schema validation.

Strengths

Handles both text and image inputs with broad capability across language understanding, reasoning, and coding tasks.

Best for

General-purpose applications requiring multimodal input, structured output generation, and a large context window.

Limitations

Superseded by newer models in the OpenAI lineup — GPT-4.1 offers higher performance as a workhorse text model, while o4-mini and o4 Mini High provide cost-effective reasoning, and GPT-4o-mini offers a more compact alternative.
