Prompt Evaluation

Evaluating a prompt means testing it against a fixed set of cases before and after any change, not just eyeballing a few outputs.

Model Evaluation in Production

Production model evaluation tracks quality continuously against real traffic, not just a one-time benchmark before launch.

LLM Observability Tools

Tools like Langfuse, LangSmith, and Arize Phoenix trace every model and tool call so a developer can see exactly what happened.

Cost Monitoring for AI

Monitoring AI cost means attributing token spend to specific features, users, or tenants, not just watching one total bill.

Reliability & Fallbacks for AI Systems

Reliable AI systems define a fallback model or provider, retry policy, and timeout before a provider outage ever happens.

Prompt & Model Versioning

Versioning prompts and pinning model versions makes behavior changes traceable instead of silent.

CI/CD for GenAI

CI/CD for GenAI runs prompt and evaluation suites automatically before a prompt or model change ships to production.
