About this tag
The openai api tag covers practical guidance for developers and IT teams building applications that connect to OpenAI models. Topics include the Responses API, official SDK usage, separate API billing, key and secret handling, and the risks of exposing credentials in Windows clients or browser-based tools. Tagged discussions also examine GPT-5.6 Sol, Terra, and Luna availability, model selection, prompting methods that may reduce token use, and the current lack of fine-tuning support for those models. Examples include PowerShell utilities, .NET services, Teams bots, desktop applications, WordPress integrations, and internal portals, with attention to structured output, automation, security, and validating model behavior before deployment.

    GPT-5.6 Luna Is Live — Do Not Replace It With GPT-4o

    SitePoint’s August 10 guide to “GPT-5.6 Luna” contains a disclaimer that tells developers the model is hypothetical, that gpt-5.6-luna will not resolve on the live OpenAI API, and that readers should replace it with gpt-4o before running the examples.

    OpenAI Responses API: Keep Keys Out of Windows Clients

    Analytics Insight’s August 6 tutorial, “OpenAI API Tutorial: Build Your First AI Application,” correctly frames OpenAI’s API as a way to add text, image, and other AI capabilities without training a model.
