Which AI model should I use?
Describe what you're about to do. Tierpik picks the model, the exact setting and the app, so you stop burning your usage limits on the wrong one.
Questions
Which AI model should I use?
Use the lightest model that does the job well, and step up only when you see a specific failure. Quick questions, emails, rewrites and summaries rarely need a top model; debugging, analysis and long documents need a reasoning model; only the hardest problems need a frontier model. Tierpik makes that call for your exact task and plan.
Why do I keep hitting my ChatGPT or Claude usage limit?
Usually three things: using the heaviest model or thinking level for everything, very long chats (every new message re-reads the whole conversation), and agent tools like Claude Code, Codex or deep research that draw from the same allowance. Lighter models for routine work and fresh chats with a short summary make the biggest difference.
Is ChatGPT's everyday chat unlimited?
As of November 2026, everyday text chat on the Instant model is listed as unlimited on every ChatGPT plan, subject to abuse guardrails. Thinking levels, GPT-6 Pro, deep research, images and the Work/Codex allowance are metered separately.
Does Claude Code share limits with Claude chat?
Yes. On Claude's paid plans, chat, Claude Code and other features draw from the same session and weekly limits, so a long coding session leaves less for chat.
How does Tierpik decide?
Each task has a minimum quality tier. Tierpik picks the cheapest model on your plan that clears it, tells you the exact setting (effort, thinking level or mode) and which limit it uses, and gives you a step-up path if it falls short. Stakes and input size raise the bar; 'Save limits' starts one tier lower.
Is Tierpik free? Do you store what I type?
Tierpik is free and needs no sign-up. Recommendations are computed in your browser; your app choices are saved only on your device. If you click 👍 or 👎 we record the task type, the recommended model and your vote, never the text you typed.
Can I use Tierpik inside Claude or ChatGPT?
Yes. Add https://mcp.tierpik.com/mcp as a custom connector in Claude, ChatGPT (developer mode), Gemini, Grok or Perplexity, then ask: "Using Tierpik, which model should I use for this?"
