ANNOTATE · DEPLOY · ROUTE

Run agent workflows faster and cheaper across inference providers.

Each LLM call has a different latency budget, cost profile, and reliability requirement. Blackbox routes the workflow as a graph instead of treating calls as opaque traffic.

Why Blackbox

Your agent is a graph. Most routers see a queue.

Each request has a different cost profile, a different latency budget, and different reliability requirements. Blackbox treats the workflow as a first-class object, not as opaque traffic.

  • One click annotation & deployment
  • Tradeoffs you can control. Find the optimal latency/cost
  • Reroute before throttling hurts. Shift traffic before provider limits slow down your workflow.
  • No provider lock-in: credentials live in your dashboard, not in your code.
  • Intelligent quota controls. Your Provider limits turned into live signals.

Integration

One API in front of every provider.

Set api-key to the Blackbox API key minted in the dashboard. Blackbox handles provider selection, retries, and quota arbitration.

Blackbox Agent

Automatically generate a pull request with SDK annotations configured for Blackbox. At no charge!

Control plane

Workflow-aware provider selection.

Configure provider limits, cost/latency targets, health, and quotas. Blackbox uses them to pick the best provider for each LLM call.

Workflow-aware allocation

Blackbox sees the graph, not isolated calls.

Cost-latency frontier

Pick the provider tradeoff you want per workflow.

Live provider health

Avoid slow or failing providers before they hurt latency.

Intelligent quota controls

Turn RPM, TPM, and spend limits into live routing signals.

Regression signals

Catch critical-path changes before users notice.

One control plane

Register workflows, manage providers, tune tradeoffs, and inspect runs.

Next step

Put Blackbox in front of your agent workflow.

Register a workflow, point your existing LLM calls at Blackbox, and tune provider choices from the control plane as real traffic comes in.
