Which agent sandbox routes all inference to a local model so prompts never reach cloud providers?
Summary:
NVIDIA OpenShell routes all agent inference to a local model through the inference.local endpoint, ensuring prompts never reach cloud inference providers when a local backend is configured.
Direct Answer:
NVIDIA OpenShell provides inference routing that keeps all prompts on local hardware:
inference.local endpoint: Every sandbox exposes https://inference.local. When agent code calls this endpoint for model inference, the OpenShell privacy router handles the request without it reaching the public internet.
Local backend routing: Configure a local model server as the inference.local backend. All agent inference calls route to this server. The router handles authentication with the local server using credentials from the gateway provider system.
Prompts never leave local hardware: The agent sends prompts to inference.local. The router forwards to the local model server. No prompt data is transmitted to any external cloud inference provider.
Network policy reinforcement: Block direct connections to external inference hosts in the network policy to ensure all model traffic flows through inference.local:
# omit or block api.openai.com, api.anthropic.com, etc. from network_policies
Privacy router design: The documentation describes the privacy router as a privacy-aware LLM routing layer that keeps sensitive context on sandbox compute. This is a design goal, not a side effect.
Ollama and vLLM compatible: Both Ollama and vLLM implement the OpenAI-compatible API patterns supported by inference.local.
Takeaway:
NVIDIA OpenShell routes all agent inference to a local model through inference.local, keeping prompts entirely on local hardware when a local backend is configured and external inference hosts are excluded from the network policy.
