Free models let you build and iterate on your MVP without burning through runway. Start with free-tier APIs to validate your idea, test user flows, and gather feedback before committing to paid models. Many free models support function calling and streaming for production-quality prototypes.
Add AI-powered chatbots, search, summarization, or content generation to your product. Models with function calling can integrate with your backend to execute actions, while streaming provides real-time responses that keep users engaged. Budget models under $1/1M tokens keep costs predictable as you scale.
As your user base grows, AI costs can spike fast. Affordable models under $1/1M output tokens let you scale to thousands of daily users without blowing your budget. Compare price-to-quality ratios to find the sweet spot between capability and cost for your specific use case.
Open-source models give startups full control over their AI stack. Self-host to eliminate per-token costs at scale, fine-tune on your domain data for better results, and avoid vendor lock-in. Ideal for startups handling sensitive data or building in regulated industries.
