How it works

Get Started in 3 Steps

  1. Choose a model ID

    Select a public catalog model ID and review its endpoint and current starting price.

  2. Configure RunAPI

    Add the provider configuration for this agent.

  3. Verify the result

    Run the agent status and model-selection commands shown below.

What to Build with Hermes Agent + GPT

  • Complex reasoning and multi-step tasks

    Use GPT through Hermes Agent for complex reasoning, refactoring, and multi-step automated workflows.

  • Batch processing with structured outputs

    Process large document sets with schema-constrained JSON output for RAG pipelines, invoice parsing, or content classification.

  • Model routing by task complexity

    Send simple queries to a smaller GPT version and harder reasoning to a larger one, all through the same RunAPI provider and key.

Why Use GPT Through RunAPI + Hermes Agent

  • 15 variants, one API key

    Use one RunAPI connection to choose among the live model variants without changing your integration.

  • Clear usage pricing

    See current catalog pricing before you send a request, with no subscription or minimum spend required.

  • Direct responses

    Synchronous calls return the result in the same response, so your agent can use it immediately without task polling.

Hermes Agent + GPT Questions

Can I use GPT in Hermes Agent through RunAPI?

Yes. Hermes Agent supports custom OpenAI-compatible providers. Add RunAPI with the configuration shown on this page and set a GPT version from the versions list as the model.

Does the Responses API work through RunAPI in Hermes Agent?

RunAPI supports both the Chat Completions API and the Responses API for GPT. Hermes Agent can use either one with the same API key.

Can Hermes Agent switch between GPT versions per request?

Yes. Change only the model field. The provider, base URL, and API key stay the same.

Which model ID should I use?

Choose a public model ID from the version table. Each ID exposes the endpoints shown for that version.

Does this guide configure a chat model?

Yes. This Model Line supports a client-facing LLM protocol.
