Model gateways
Define the task and acceptable result for Model gateways before choosing models, prompts or supporting data.
Gromnii designs shared AI platform capabilities for model access, governance, usage and delivery.
Use AI platform engineering when multiple teams or applications need shared access to models, inference, retrieval, evaluation and policy controls. A common platform can reduce duplicated integration work while keeping routing, identity, cost and provider choices explicit.
Define the task and acceptable result for Model gateways before choosing models, prompts or supporting data.
Define AI API management with clear contracts, versioning, authorization, error behavior and ownership so connected systems can evolve without fragile point-to-point dependencies.
Represent both the normal path and material exceptions in Routing and policy.
Measure Inference infrastructure against task-specific quality, latency and cost limits rather than one generic score.
Set confidence and impact rules for Usage controls, and send uncertain cases to a person with the evidence needed to decide.
This reference shows one possible AI Platform Engineering arrangement. The actual design depends on the systems, constraints and controls involved.
Separate who may use models, deploy prompts, change routing, access evaluation data and administer platform services, with stronger controls around high-impact actions.
Track model, embedding, storage and tool-call cost by application and environment so teams can compare quality gains with the recurring expense of each design.
Define fallbacks for unavailable models, gateways, vector stores and tools, with health checks that can route traffic away from degraded AI components.
Separate application logic from provider-specific APIs where practical, but avoid abstraction layers that hide useful provider features without a real portability need.
Provide governed gateways and common APIs so applications do not each implement their own provider logic and credentials.
Track usage by application, team, model and workload so routing and capacity decisions are based on actual demand.
Add routing, fallback, quotas and observability so model-provider failures or performance changes do not become application-wide outages.
Technical implementation notes for AI Platform Engineering.
Platform scope should follow the number of applications, providers, teams, policies, and operational controls that actually need to be shared.
Provide shared foundations for teams to build AI applications with consistent access, controls, and observability.
Centralize model access, provider routing, policy enforcement, usage visibility, and application credentials.
Select models by task, quality, latency, privacy, or cost while enforcing approved usage patterns.
Run AI workloads with the capacity, isolation, latency, and operational visibility the application requires.
Use different models where their strengths matter without hard-wiring the business system to one provider.
Describe what AI Platform Engineering should change, the systems it must work with and the constraints that matter.
