What can you build with OpenAI APIs on LinkModel?

Combine OpenAI language, image, and video models in production workflows while keeping model access and usage management in one place.

Reasoning agents and knowledge workflows

Use GPT models for research, analysis, structured outputs, tool-driven workflows, and long-context knowledge tasks. Select the model tier according to required capability, latency, and cost.

Software engineering agents

Use a Codex or GPT coding model for repository analysis, implementation, debugging, migration, and terminal-driven engineering workflows.

Product and campaign imagery

Use GPT Image to generate concepts, text-rich campaign assets, product visuals, and controlled edits from approved reference images.

Short-form video and story concepts

Use Sora for video concepts that combine visual direction with motion and synchronized sound, after confirming the live endpoint and lifecycle status for the selected model.

Prompt-to-campaign pipelines

Draft campaign concepts with GPT, create approved stills with GPT Image, and turn them into video with Sora when all required model capabilities are available.

Why run OpenAI models through LinkModel?

Use the OpenAI model family alongside other leading providers without adding another account, credential, or billing workflow.

One key across OpenAI model families

Use one LinkModel API key for the supported GPT, Codex, GPT Image, and Sora models enabled in the live catalog.

OpenAI alongside other providers

Compare or combine OpenAI models with other language, image, and video providers without maintaining a separate platform account for each family.

Centralized usage and billing

Review usage and pay-as-you-go charges from one LinkModel account while selecting the model that fits each workload.

Integrate OpenAI models

Use one LinkModel credential to select a listed OpenAI model, submit the matching request, and track usage from the same account.

  1. Authenticate with one API key

    Create a LinkModel API key and use it to authenticate requests for the OpenAI models enabled for your account.

  2. Choose a model for the workload

    Select a GPT, Codex, GPT Image, or Sora model, then open its model page to confirm the current identifier, request schema, and pricing units.

  3. Submit, observe, and iterate

    Send the request, handle the response or generation task, and compare usage before moving the workflow into production.
