LLM Integration Patterns for Enterprise Applications

Integrating LLMs into enterprise applications requires careful architecture to handle latency, cost, and reliability concerns.

Key patterns: async processing for non-real-time tasks, caching for repeated queries, fallback chains across multiple providers, and output validation with structured output parsing.

Cost management is critical. Implement token budgets, use smaller models for simple tasks, and cache frequently requested completions. Monitor cost per query and optimize prompt efficiency.
