Virtual Quota Fallback

The Virtual Quota Fallback is a specialized meta-provider designed for sophisticated resource orchestration. It allows you to manage a prioritized chain of multiple AI providers, automatically switching between them based on hard usage limits or real-time availability.

This is the premier solution for developers who utilise multiple tiers—for example, exhausting a high-performing free quota before automatically falling back to a pay-as-you-go institutional account.

Operational Framework

The Fallback provider does not communicate with an LLM directly; instead, it acts as the "mission control" for your existing Sypha provider profiles.

• Priority Ranking: You define a stack of pre-configured profiles. Sypha always attempts to fulfill requests using the top-most profile first.
• Granular Usage Tracking: Set hard limits on token volume or request frequency (per-minute, hourly, or daily).
• Seamless Failover: If the current engine exceeds a limit or returns a provider error, Sypha instantly deactivates it and engages the next available provider in your hierarchy.
• Status Awareness: Sypha provides non-intrusive notifications whenever an automatic fallback event occurs.

Implementation Guide

1. Prerequisite Setup

Ensure you have already initialized at least two independent provider profiles (e.g., "DeepSeek Free" and "OpenAI Professional") within Sypha.

2. Provider Selection

Open Sypha settings and choose Virtual Quota Fallback from the registration menu.

3. Constructing the Chain

• Add Profiles: Select your pre-configured profiles from the fallback registry.
• Calibrate Limits: (Optional) Define token or request ceilings for each profile. If left blank, the profile remains active until a provider-side error occurs.
• Set Priority: Utilise the directional arrows to order your providers. The "Primary" engine should always sit at the top.

4. Live Usage Monitoring

The Fallback configuration view doubles as a real-time analytics dashboard:

• Instant Stats: View token and request volume for the last minute, hour, and day for every profile in the chain.
• Manual Reset: Use the Clear Usage Data tool to zero-out local statistics and instantly re-enable any limit-blocked providers.

Strategic Tips

• Prioritize Economics: Place your most cost-effective or free-tier engines at the top of the stack.
• Resilience Calibration: If no limits are defined, the fallback acts as a "reliability insurance" policy, only switching if a provider suffers an outage.
• Registry Constraints: You cannot nest a Virtual Quota Fallback profile within another fallback chain, as this would create a circular dependency.
