GPT-4o (2024-08-06)

GPT-4o is OpenAI's flagship multimodal model in the gpt-4o family, designed to process both text and image inputs while producing natural language output. The August 2024 release, officially named gpt-4o-2024-08-06, was introduced alongside a price reduction, positioning it as a more economical option for developers building production systems. Compared with its immediate predecessor, this snapshot lowered input token costs substantially and output token costs by a third, making sustained conversational and analytical workloads more practical at scale. The defining addition in this version is first-class Structured Outputs support, where the model guarantees that generated responses will exactly match a developer-supplied JSON Schema, which is a meaningful step toward reliable downstream parsing and tool integration.

The August 2026 snapshot sits within the broader gpt-4o lineage that OpenAI describes as reaching gpt-4 Turbo parity on text, reasoning, and coding benchmarks while extending stronger multilingual, audio, and vision performance. For practitioners, the practical strengths of this variant are the combination of dependable structured generation with the multimodal understanding already established across the family, which fits use cases such as schema-constrained data extraction from documents, agent pipelines that require strict function call shapes, and vision-grounded assistants that must return machine-parseable answers. Its design intent leans toward developers who need predictable output formats without giving up the general reasoning and vision competencies that made the gpt-4o family a popular default for mixed-modality applications.
