ModelFlow is an AI orchestration platform that provides a unified API layer for accessing and managing multiple large language models (LLMs) and specialized AI agents from various providers (e.g., OpenAI, Anthropic, Google, open-source models). It solves the problem of vendor lock-in and service fragility, as highlighted by Anthropic cutting off OpenAI’s access to its models, by enabling seamless switching between models, intelligent routing based on cost or performance, and built-in fallback mechanisms. Businesses can develop AI-powered applications with greater resilience, flexibility, and cost efficiency, without being tied to a single AI provider’s terms or availability.
