You can register agents on Vijil that use Groq-hosted models such as `llama-3.1-8b-instant`, `llama-3.3-70b-versatile`, `openai/gpt-oss-120b`, and `openai/gpt-oss-20b`. ## Prerequisites * You have a Groq account with an active API key. * Your Groq account has access to the models you plan to use. * You have access to a Vijil team and permission to manage **[Keys](https://evaluate.vijil.ai/keys)** and **[Agents](/tutorials/manage-agents/)**. ## Store Groq Credentials in Vijil 1. In Vijil, go to **[Keys](https://evaluate.vijil.ai/keys) > Add new key**. 2. From the **Model Hub** dropdown, select **Groq**. 3. Enter your Groq API key and any optional rate limit overrides you want for this key. 4. Save the key configuration. Once saved, this key can be reused across multiple Groq-based agents. ## Register an Agent on Vijil With a Groq API key configured, you can register an agent that uses Groq: Setting up a Groq-based Agent in Vjil 1. Press **Register Agent**. 2. Enter an [Agent](/tutorials/manage-agents/) name. 3. Select **Groq** as the **Hub**. 4. Enter a model name (for example `llama-3.1-8b-instant` or `openai/gpt-oss-120b`). See the Groq documentation for the list of available models. 5. Select an existing Groq API key you configured earlier, or create a new one. 6. Add a **System Prompt** if you want Vijil to send a default system prompt with every request to this agent. ## Enterprise If your organization uses enterprise-only features with Vijil: 1. Add an **MCP server URL** so the agent can access MCP tools exposed by that server. 2. Add an **A2A Agent Card URL** so this agent can participate in agent-to-agent workflows defined in your enterprise.
