SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) and references (resource) components.

What problem does it solve?

Manages multiple LLM providers, normalizing responses, and simplifying fallback and cost tracking.

Core Features & Use Cases

  • Unified Interface: Calls LLMs via a single format, regardless of the provider.
  • Provider Routing: Routes requests to different providers based on configuration.
  • Fallbacks & Retries: Implements fallback to other providers and retries on failure.
  • Cost Tracking: Tracks costs associated with LLM calls.
  • Use Case: When building a system that requires multiple LLM providers and needs to manage costs and reliability efficiently.

Quick Start

Use the litellm-usage skill to call an LLM with the model "openai/gpt-4o".

FAQPage Schema
How do I manage multiple LLM providers through a unified interface?▼

A unified interface manages calls to 100+ LLM providers by normalizing responses into a single format, allowing you to interact with different models without changing your request structure.

What is the best way to handle LLM fallbacks and retries on provider failures?▼

Handling LLM fallbacks and retries involves configuring provider routing to automatically redirect requests to alternative models, ensuring system reliability and continuous operation during provider outages.

How do I track LLM API costs across different providers?▼

Tracking LLM API costs requires a system that monitors and aggregates expenses associated with each LLM call across 100+ providers, providing visibility into multi-provider spending.

Can I route LLM requests to specific providers based on my configuration?▼

Yes, provider routing directs requests to different LLM providers based on your custom configuration, allowing flexible management of model traffic and distribution.

When do I need a unified LLM interface for my application?▼

You need a unified LLM interface when building systems requiring multi-provider LLM support, enabling efficient management of both operational costs and routing reliability across diverse models.

Does this unified interface work with 100+ LLM providers without extra dependencies?▼

Yes, the unified interface manages calls to 100+ LLM providers natively with no external dependencies required, normalizing responses and simplifying integration into your existing stack.
