cascadeflow
Cascading runtime for AI agents. Optimize cost, latency, quality, and policy decisions inside the agent loop.
CascadeFlow is an agent runtime intelligence layer that dynamically optimizes AI agent workflows by intelligently routing queries between cost-efficient and premium models. It uses speculative execution to try cheaper models first, then automatically escalates to more powerful models only when quality validation fails, delivering 40-85% cost savings while maintaining quality. The library works as an in-process harness that integrates with LangChain, OpenAI Agents SDK, CrewAI, PydanticAI, Google ADK, Hermes Agent, n8n, and Vercel AI SDK, providing multi-dimensional optimization across cost, latency, quality, budget enforcement, compliance, and energy.
Key Features
Use Cases
- 01Reduce AI infrastructure costs by routing simple queries to efficient models and complex ones to premium models
- 02Enforce per-user budget limits and compliance policies (GDPR, HIPAA) directly in agent execution loops
- 03Optimize LangChain or CrewAI multi-agent workflows with automatic model selection per task complexity
- 04Run edge-optimized agents that handle most queries locally via Ollama/vLLM and escalate to cloud only when needed
- 05Add real-time cost tracking and energy consumption monitoring to production AI agent systems
- 06Implement domain-specific routing for specialized tasks like code generation, medical queries, or financial analysis

cascadeflow — FAQ
What is CascadeFlow?+
CascadeFlow is an in-process intelligence layer for AI agents that optimizes model selection through speculative execution, trying cheap models first and automatically escalating to premium models only when quality validation fails. It works inside the agent loop to optimize cost, latency, quality, budget, compliance, and energy consumption.
How do I install CascadeFlow?+
For Python, run 'pip install cascadeflow' or 'pip install cascadeflow[all]' for full features. For TypeScript/Node.js, run 'npm install @cascadeflow/core'. Framework-specific packages are available via 'npm install @cascadeflow/langchain' or 'pip install cascadeflow langchain-openai'.
Which AI frameworks and clients does CascadeFlow work with?+
CascadeFlow integrates with LangChain, OpenAI Agents SDK, CrewAI, PydanticAI, Google ADK, Hermes Agent, n8n, Vercel AI SDK, and custom agent frameworks. It supports 17+ AI providers including OpenAI, Anthropic, Groq, Ollama, vLLM, Together, and works in Python and TypeScript.
Do I need API keys to use CascadeFlow?+
Yes, you need API keys for the AI providers you want to use (e.g., OpenAI, Anthropic). CascadeFlow itself is a routing library that requires your existing provider credentials. Local providers like Ollama and vLLM don't require API keys.
Is CascadeFlow free to use?+
Yes, CascadeFlow is MIT-licensed and free for commercial use. You only pay for the underlying AI provider API costs, which CascadeFlow aims to reduce by 40-85% through intelligent routing.
How does CascadeFlow achieve cost savings?+
CascadeFlow uses speculative execution to try cost-efficient models first (e.g., $0.15/1M tokens) and only escalates to premium models (e.g., $5/1M tokens) when quality validation fails. Research shows 60-70% of queries don't need flagship models, enabling significant cost reduction without quality loss.
