You can register agents on Vijil that use NVIDIA NIM models such as `nvidia/llama3-chatqa-1.5-8b`, `nvidia/llama3-chatqa-1.5-70b`, and `nvidia/nemotron-4-340b-instruct`. ## Prerequisites * You have an NVIDIA NIM or NVIDIA API account with an active key. * Your account has access to the NIM 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 NVIDIA credentials in Vijil 1. In Vijil, go to **[Keys](https://evaluate.vijil.ai/keys) > Add new key**. 2. From the **Model Hub** dropdown, select **NVIDIA**. 3. Enter your NVIDIA 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 NVIDIA-based agents. ## Register an Agent on Vijil With a NVIDIA API key configured, you can register an agent that uses NVIDIA NIM: Setting up an NVIDIA-based Agent in Vjil 1. Press **Register [Agent](/tutorials/manage-agents/)**. 2. Enter an [Agent](/tutorials/manage-agents/) name. 3. Select **NVIDIA** as the **Hub**. 4. Enter a model name (for example `nvidia/llama3-chatqa-1.5-8b`). See the NVIDIA NIM documentation for the list of available models. 5. Select an existing NVIDIA 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.
