DecisionHypervisor vs. AI Gateways
AI gateways and LLM proxies sit in front of model providers. They route requests, balance load, apply rate limits, inspect prompts and responses, and increasingly provide model-firewall capabilities against injection and unsafe outputs. That is valuable infrastructure — but it governs model traffic, not consequences. The object passing through a gateway is a request and a completion; the object passing through DecisionHypervisor is a proposed action with an actor, a target, and real-world effect. A refund, a deploy, a firewall change, or a payment is not a model call, and it cannot be governed by one.
What AI Gateways and LLM Proxies Does Well
- Model routing, failover, and load balancing across providers
- Rate limiting, quotas, and cost controls
- Prompt and response inspection, injection defense, and content filtering
- Unified API surface across model vendors
- Latency and usage observability for model traffic
Where the Category Stops
- Governs the conversation, not the consequence — a safe completion can still precede an unauthorized action
- No authority model for the actor behind the request: who may cause what, on which target, under which conditions
- No per-action Decision Object, escrow, or human-review resolution
- Cannot verify that the action which followed the answer actually occurred as authorized
| Dimension | AI Gateways and LLM Proxies | DecisionHypervisor |
|---|---|---|
| Object governed | Model requests and completions | Proposed consequential actions |
| Primary question | Which model should answer this, and is the exchange safe? | May this actor cause this effect, on this target, under these conditions? |
| Trust boundary | Between application and model provider | Between anything that proposes and anything that executes |
| What 'enforcement' means | Rate limits, content filters, model-firewall blocks | Allow, modify, escrow, route for review, or deny the action itself |
| Human review | Alerting and logging on traffic | Authority-bearing resolution states wired into the decision itself |
| Evidence produced | Request logs and traffic analytics | Hash-chained, signed decision records linked to outcomes |
The DecisionHypervisor Difference
- Governs the action layer: every consequential proposal resolves to an explicit decision before execution
- Binds actor, action, target, context, and authority into one evaluated object — independent of which model produced the proposal
- Issues narrow, single-transaction Execution Grants verified at the target connector — the model is never the trust boundary
- Records tamper-evident proof of what was decided and what actually happened
- Complements gateways: route traffic through the gateway of your choice; authorize actions through DecisionHypervisor
DecisionHypervisor is model- and gateway-neutral. Keep the gateway for model routing and filtering; DecisionHypervisor evaluates the action an agent proposes after any model, gateway, or orchestrator has produced it.
"Thesis: Gateways govern what the model says. DecisionHypervisor governs what the system does."
