What to Build with Hermes Agent + Grok

  • Agent coding and reasoning

    Let your agent plan, write, and review code or work through multi-step problems with the model's reasoning.

  • Long document analysis and extraction

    Summarize reports, contracts, or codebases and pull structured fields out of long documents.

  • Tool-calling workflows

    Connect the model to functions and APIs so your agent can look up data and take actions between replies.

Why Use Grok Through RunAPI + Hermes Agent

  • 4 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 + Grok Questions

Which model ids should I use for Grok?

Use the public model ids grok-4.5 or grok-4.6 shown in the quickstart.

Can Grok call function tools through Responses?

Yes. Send flat Responses function definitions in tools and read the returned name and JSON arguments from function-call output items.

Do Grok 4.5 and 4.6 support structured JSON output?

Yes. Use text format with a strict JSON Schema for Responses, or response format for Grok Chat Completions.

How should I stream Grok Responses?

Treat a Responses stream as complete only after response.completed, terminal usage, and the final done marker.

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.
