We hear a lot about artificial intelligence that can write, code, or generate images. But inside an application, AI does not always need to produce a long answer.
Sometimes it simply needs to make a decision.
That is exactly what OpenAI’s new Decisions API, announced on October 22, 2026, offers.
AI for targeted decisions
Imagine an application receiving hundreds of requests.
Some need to be classified, others routed to the right department. Others require choosing the next step in an automated process.
Rather than always asking for a conversational response, the Decisions API lets you work with predefined choices.
The goal is to reduce processing time and costs for these operations.
According to OpenAI, some decisions can be made up to ten times faster than with GPT-6 Luna through the Responses API.
What does this mean for developers?
This approach opens up interesting possibilities for web applications and automation workflows.
Possible uses include:
- Classifying user requests.
- Routing requests to different services.
- Selecting a step in a workflow.
- Structuring certain decisions made by AI agents.
Faster does not always mean more reliable
This is a crucial point.
A fast response still needs to be evaluated. Reported performance does not replace testing, error handling, or oversight of sensitive decisions.
In my view, the real benefit is architectural: using AI where it adds value, without turning every operation into a complex conversation.
The future of AI-assisted development may not be just about ever more powerful models.
It also involves more specialized tools that are better integrated and suited to real needs.
