LLM Application
Architecture
A production LLM application needs more than a connection to a model API.
Layer 01
Application Logic
Control the task, workflow rules, permissions and application behavior surrounding each model request.
Layer 02
Prompt and Context
Provide the model with clear instructions, conversation state, examples and application specific context.
Layer 03
Model Routing
Select the appropriate model according to task complexity, quality requirements, latency and operating cost.
Layer 04
LLM Inference
Process each request using the commercial or open language model selected for the workload.
Layer 05
Structured Outputs
Return predictable schemas, JSON or application specific formats where downstream systems require them.
Layer 06
Output Validation
Check generated values, formats and application rules before another system uses the model response.
Layer 07
Observability
Track model calls, latency, failures, token usage and application behavior.
Layer 08
Application Response
Deliver the validated result through the product, API, workflow or user interface.
Model Selection
and Routing
The best model depends on the task. We select and route models according to what the application actually needs.
Reasoning
OpenAI

Domain Terminology
Adapt suitable models to handle specialized terminology more consistently.
Formats
Structured Outputs
Improve performance on tasks where predictable formats are important.
Routing
Classification
Adapt models for repeatable intent, routing and categorization tasks.
