OpenAI introduces Structured Outputs and reduces GPT-4 pricing by 50%. Structured Outputs ensure model outputs match developer-supplied JSON Schemas, addressing a challenge since function calling was introduced. Developers can implement this by setting `strict: true` in function definitions or as a `response_format` option. The latest GPT-4 version also offers a 50% reduction in input token pricing and a 33% reduction in output token pricing.
