How to Choose the Right LLM for Your MVP in 2026

Picking an LLM for an MVP should be a product decision, not a hype decision.

Evaluate on four axes

1. Capability: does the task really need a frontier model?
2. Cost: what is acceptable cost per request at your target volume?
3. Latency: what p95 response time is acceptable for your UX?
4. Reliability: do you have fallback providers for outages and rate limits?

Recommended approach

• Start with a mid-tier hosted model for speed.
• Add a premium fallback for hard prompts.
• Route simple tasks to cheaper models.
• Track quality and cost weekly with an eval suite.

For most MVPs, this gives the best tradeoff between shipping velocity and long-term cost control.
