AI Model Selector Helper
Compare your task needs against AI model strengths to help pick the right LLM for cost, speed or quality, free and instant in your browser.
What are you doing?
Recommendation
A balanced mid-tier model (Claude Sonnet, GPT-4o, Gemini Pro class) — a good default for most tasks.
- →Model names change fast — treat these as classes, not fixed picks.
General guidance by model class — rule-based, runs in your browser. Verify current model capabilities and pricing with the provider.
How to use this calculator
- Pick your main task and top priority.
- Tick long-input or image-generation if they apply.
- Read the recommended model class and the tips.
How it works
The helper maps your task and priorities to a class of model — small/fast for cost and speed, frontier for quality, large-context for big inputs, a dedicated image model for pictures, and local/zero-retention for privacy.
It advises by class, not specific products, because model names and prices change quickly. Verify the current options with the provider.
Frequently asked questions
Does this use AI or send my prompt anywhere?
No. It runs entirely in your browser using rule-based checks — your prompt is never uploaded or sent to any AI model. Still, avoid pasting passwords, API keys or private data into any tool.
Why not name exact models?
They change constantly. Classes (small/fast, frontier, large-context, image) stay stable, so the advice doesn't go out of date.
