OpenAI has announced two significant updates to its API offerings: the introduction of Structured Outputs and a substantial price reduction for its latest GPT-4 version.

Structured Outputs: Ensuring Schema Compliance

OpenAI has launched Structured Outputs, one of the most requested features for its API. This feature ensures that model outputs precisely match developer-supplied JSON Schemas, addressing a long-standing challenge since the introduction of function calling.

Developers can implement Structured Outputs in two ways:

1. For function calling: Set strict: true within the function definition.
2. As a response_format option: Supply a json_schema with a full schema definition and set strict: true.

Structured Outputs with function calling is supported across all function-calling-capable models, including GPT-4 and GPT-3.5-turbo variants.

Significant Price Reduction

The latest GPT-4 version (gpt-4o-2024-08-06) comes with substantial cost savings for developers:

• 50% reduction in input token pricing
• 33% reduction in output token pricing

Compared to the previous version, these price cuts make advanced AI capabilities more accessible to a broader range of developers and applications.

OpenAI encourages developers to explore these new features and looks forward to seeing the innovative applications that will emerge from these enhancements.
