AI app for it and development · no coding needed
Unified model routing and spend control workspace
Reduce integration and provider-management effort while keeping model traffic, keys and spend under the buyer's control.
Made for: Engineering teams and platform owners routing production AI traffic across several model providers

What it does for you
The problem
Teams integrate each model provider separately, cannot see or cap combined spend, and have no tested fallback when a provider degrades.
What it gives you
Reviewed gateway configuration with measured routing and spend reports

How it works, step by step
- Register provider accounts and bring-your-own keys
- Expose one OpenAI-compatible endpoint
- Route requests by cost, speed or task rules
- Retry and fall back to alternative models on failure or timeout
- Cache responses to cut repeat cost and latency
- Multiplex across models to improve utilization
- Handle text, vision, video and speech workloads
- Benchmark providers on price, latency and load
- Apply rate limits across combined provider usage
- Track token usage, cost and spend by team
- Set budget caps and cost alerts
- Run built-in evaluations and regression tests
- Orchestrate multi-agent and multi-model chains
- Scope provider and model access per application key
- Compare the reviewed result with the recorded baseline and value assumptions
- Capture corrections and named-owner approval before consequential use
- Export a versioned reviewed gateway configuration with source references and unresolved questions

Questions
Do I need to know how to code?
No. You copy and paste the prompts on this page into ChatGPT or Claude, and the AI does the building. When it asks you something, you answer in your own words.
What does it cost?
The quick version, the app pack and the step-by-step instructions are for members: you pay the membership price, not a price per app (see the plans). Building the full app uses your own ChatGPT or Claude subscription. Putting it online is often cheap or no cost at the start, and your AI tells you before anything costs money.
How long does it take?
The quick version: about two minutes. The real app: an afternoon for a first version you can use, longer if you want every feature.
Can I change it to fit my business?
Yes. Tell your AI what to change in plain words, like “add a column for the price” or “use our logo and colours”. Or have Nexibeo build and customise it for you.
More detailsHow the AI works, safeguards and what to build first
Reduce integration and provider-management effort while keeping model traffic, keys and spend under the buyer's control. For engineering teams and platform owners routing production AI traffic across several model providers, convert provider accounts, application keys, routing rules and budget limits into a reviewed gateway configuration with measured routing and spend reports. The benefit is a testable hypothesis, measured through requests served per provider incident and cost per accepted response; do not assume that AI output alone produces business value.
Confirm the buyer's problem and scope, collect provider accounts, application keys, routing rules and budget limits, then follow this sequence: 1. Register provider accounts and bring-your-own keys. 2. Expose one OpenAI-compatible endpoint. 3. Route requests by cost, speed or task rules. Resolve uncertain cases with qualified reviewers, approve reviewed gateway configuration with measured routing and spend reports, and measure requests served per provider incident and cost per accepted response against a documented baseline.
How the AI works
Use AI to interpret permitted inputs, suggest structured mappings and generate candidate outputs for the three stated task modules. Use deterministic code for arithmetic, schema validation, hard constraints and reproducible tests. Review source-linked explanations and uncertainty before accepting results. One self-hosted deployment and one approved provider set; final routing policy and spend decisions remain engineering. A model suggestion is never a verified fact, professional decision or authorization to act.
Safeguards
Preserve key security, source attribution, routing accuracy and usage permissions. Engineering owners approve substantive changes and deployment scope. One self-hosted deployment and one approved provider set; final routing policy and spend decisions remain engineering. Keep all consequential actions under authorized human control and do not fabricate missing inputs, permissions, professional judgments or market evidence.
What to build first
Pilot scope: One self-hosted deployment and one approved provider set; final routing policy and spend decisions remain engineering. Implement one approved input format, a bounded representative case set and the first two task modules: register provider accounts and bring-your-own keys; expose one OpenAI-compatible endpoint. Support the third module with operator review: route requests by cost, speed or task rules. Include source references, corrections, basic organization access, approval states, export and value measurement. Use managed operator assistance for unresolved exceptions. The cost estimate covers this narrow prototype, not unrestricted multi-tenant scale, complex production integrations, specialist certification or physical operations.
What it can connect to
Provider APIs, application code repositories, observability tools and billing systems. Cloud or on-premise deployment, log export and alerting destinations. Start with file exchange and validate destination specifications before promising direct publishing. Start with authorized file exchange. Validate current provider access, usage rights and schema behavior before promising a connector.
The screens in detail
Primary screens: Provider and key registry, Routing and policy editor, Live traffic and spend dashboard. Use a provider list with health and latency, a central rule editor for routing, fallback and caps, and a right-hand panel for request logs, evaluations and comments. Let users compare routing policies side by side. Display draft, changes requested and approved states. Provide a client preview link with comments anchored to the relevant policy. Make the task-specific outcome reviewed gateway configuration with measured routing and spend reports visible beside its evidence, review state and value baseline.
