AI Rate CardOpenAI: GPT-4o (2024-08-06) · fastrouter
GPT-4o (August 2024 version) enhances OpenAI's flagship multimodal model with sophisticated structured output capabilities. This specific release introduces advanced JSON schema support through the response_format parameter, enabling precise control over output structure and data formatting for applications requiring consistent, well-defined response patterns. The model maintains all core GPT-4o capabilities: processing both text and image inputs while generating high-quality text outputs with double the speed and 50% greater cost efficiency than GPT-4 Turbo. Additional refinements include improved non-English language processing and enhanced visual analysis capabilities. Released in August 2024, this version particularly benefits developers building data-driven applications, APIs, and systems requiring predictable, structured information exchange with minimal post-processing. It represents an important evolution in OpenAI's efforts to make their models more useful for programmatic and enterprise applications requiring strict output formats alongside traditional natural language generation.
