}Multi-Provider AI Gateway & Intelligent Model Switchyard
Enterprise LLM proxy that dynamically routes queries across Claude, OpenAI, DeepSeek, and Groq based on cost, context window, latency SLAs, and automatic fallback circuits.
Reduces monthly LLM inference expenditures by 30% to 50% with sub-50ms failover switching.
Core Deliverables Included:
Client application dispatches request to unified gateway endpoint.
Gateway checks Redis semantic cache; returns cached result if hit (> 0.96 cosine).
Router classifies complexity and selects optimal provider based on cost/latency SLA.
If primary provider returns 5xx or rate limit, cascade to secondary within 48ms.
Log token usage, execution latency, and exact cost metrics to PostgreSQL.
