| 17 | +## Model Overview |
| 18 | + |
| 19 | +OpenAI’s flagship model and one of its best offerings as of late April 2026. Designed for maximum quality, reliability, and performance in critical or high-precision workloads. Ideal for advanced reasoning, premium generation quality, and complex production workflows.\ |
| 20 | +This model can only be called via the `/responses` endpoint. |

| 28 | +<summary>How to make the first API call</summary> |
| 29 | + |
| 30 | +**1️⃣ Required setup (don’t skip this)**\ |
| 31 | +▪ **Create an account:** Sign up on the AI/ML API website (if you don’t have one yet).\ |
| 32 | +▪ **Generate an API key:** In your account dashboard, create an API key and make sure it’s **enabled** in the UI. |
| 33 | + |
| 34 | +**2️ Copy the code example**\ |
| 35 | +At the bottom of this page, pick the snippet for your preferred programming language (Python / Node.js) and copy it into your project. |
| 36 | + |
| 37 | +**3️ Update the snippet for your use case**\ |
| 38 | +▪ **Insert your API key:** replace `<YOUR_AIMLAPI_KEY>` with your real AI/ML API key.\ |
| 39 | +▪ **Select a model:** set the `model` field to the model you want to call.\ |
| 40 | +▪ **Provide input:** fill in the request input field(s) shown in the example (for example, `messages` for chat/LLM models, or other inputs for image/video/audio models). |
| 41 | + |
| 42 | +**4️ (Optional) Tune the request**\ |
| 43 | +Depending on the model type, you can add optional parameters to control the output (e.g., generation settings, quality, length, etc.). See the API schema below for the full list. |
| 44 | + |
| 45 | +**5️ Run your code**\ |
| 46 | +Run the updated code in your development environment. Response time depends on the model and request size, but simple requests typically return quickly. |
| 47 | + |
