GPT 5 Coding - New Params and Tools

This video originates from the OpenAI Cookbook, which provides example code snippets and guidance for developers using the OpenAI API. In particular, the “GPT-5 New Params and Tools” entry illustrates how to leverage new capabilities when building your own applications or integrations with GPT-5.

Here are the key features highlighted:

Verbosity parameter: Set to low, medium, or high to control how concise or detailed GPT-5’s responses are.

Reasoning_effort parameter: Options like minimal, low, medium, or high let you control how much internal reasoning the model performs before responding. Choose “minimal” for faster but simpler outputs, or “high” for more analytical tasks.

Free-form function calling: Unlike standard JSON-structured function calls, this allows GPT-5 to emit raw text payloads—like Python code, SQL, shell commands, or configuration—directly to your custom tool or runtime environment .

Context-Free Grammar (CFG): Also included in the Cookbook entry you mentioned (though the snippet preview didn’t detail it), this likely offers structured parsing or generation utilities—useful for precise outputs.

These tools are designed for developers using the GPT-5 API to build smarter, more efficient, and highly tailored applications.
