How the Cascade Routing Works
When a customer asks a question, Crescelo’s orchestrator attempts inference through a priority tier chain:
Priority 1Groq Cloud Free Tier (Sub-Second Llama 3.3 70B)
Processes the request in ~300ms using Groq’s ultrafast LPU hardware. Provides up to 14,400 free requests per day.
Priority 2 (Failover)Google Gemini Flash Free Tier
If Groq hits a momentary tokens-per-minute ceiling, requests seamlessly cascade to Google Gemini Flash with massive 1M context.
Priority 3 (Local Fallback)Local Ollama Server
If both cloud free tiers are unreachable, Crescelo attempts to dispatch to any running local Ollama instance on your machine.
