Top 10 AI Model Brokers for Commercial MicroSaaS
What Are AI Model Brokers?
AI Model Brokers are platforms that act as middlemen between users and multiple hosted AI models from different providers. Instead of hosting or developing models, brokers offer a unified API and billing system to access a variety of models (e.g., ChatGPT, Claude, Mistral, Command R+, LLaMA, etc.) from multiple vendors in one place.
How Are They Different from AI Marketplaces?
AI Marketplaces
- Provide downloadable or API-accessible models
- Developers must often host and maintain models
- Ideal for custom workflows, training, fine-tuning
- Examples: Hugging Face, AWS Marketplace
AI Model Brokers
- Offer unified APIs to call many models (LLMs, vision, etc.)
- No hosting required — usage is metered per call
- Great for SaaS apps with variable demand
- Examples: OpenRouter, AI Gateway, GroqCloud
How to Use Brokers in MicroSaaS
- Start with a broker API (like OpenRouter or Together AI)
- Pick models with fast response and good commercial terms
- Integrate via REST or SDK to power features like chatbots, summarization, image generation, etc.
- Use usage-based billing to manage operating costs
- Switch models behind the same API without major code changes
