For startups, every dollar counts. The good news is that the AI coding landscape in 2026 offers excellent models at very affordable prices. You don't need to use the most expensive model to build a great product.
The sweet spot for startups is Claude Sonnet 4 ($3/M input tokens) or GPT-4o ($2.50/M input tokens) — both deliver pro-level coding capability at mid-range prices. For non-critical tasks like code review and documentation, drop down to budget models like GPT-4o mini ($0.15/M) or Gemini 2.0 Flash ($0.10/M).

Frequently Asked Questions
How much does AI coding cost for a startup?
With smart model selection, a small startup can spend $50-200/month on AI coding APIs — far less than the $20-40/user/month for GitHub Copilot or Cursor.
Should startups use one model or multiple?
Use a tiered approach: one quality model (Sonnet 4 or GPT-4o) for core development, and a budget model (GPT-4o mini or Gemini Flash) for code review and simple tasks.
