Which LLM Should I Use?

With 88 AI models available in 2026, choosing the right one is harder than ever. Performance varies dramatically by task — the best coding model isn't necessarily the best for writing, and the cheapest option may cost you in quality. This quiz uses real benchmark data from BenchLM.ai to match your requirements to the models that actually perform best for your use case.

The recommendation engine scores each model using a weighted algorithm based on your answers. Use case selection determines which benchmark categories matter most (coding, math, knowledge, or reasoning). Budget and context window filters narrow the field, and the open-weight preference lets you prioritize self-hostable models. Results link directly to detailed model profiles and head-to-head comparisons so you can verify the recommendation with data.
