The best AI for each task

• The best AI for coding — Long files fit in one pass and the step-by-step reasoning catches subtle logic errors.
• The best AI for writing — Produces prose with fewer clichés and holds a consistent voice across long pieces.
• The best AI for translation — Wide language coverage at a low cost, so you can translate long texts without watching the bill.
• The best AI for studying — Fast, cheap answers mean you can keep asking follow-up questions until it clicks.
• The best AI for long documents & PDFs — The largest context window here, so a long report goes in whole instead of being chopped up.
• The best AI for data analysis — Reliable at reading tables and turning numbers into a plain-language explanation.
• The best AI for business & planning — Good at structured business formats and at pushing back with the risks you did not ask about.
• The best AI for research — Broad general knowledge and a habit of laying out trade-offs rather than picking blindly.
• The best AI for fast answers — Specialised hardware makes the first words appear almost immediately.
• The best AI for a tight budget — Among the lowest prices per million tokens while still handling reasoning and code.
• The best AI for writing emails — Reliably hits the register you ask for — formal, warm, or blunt — and keeps it short.
• The best AI for resumes & cover letters — Keeps a consistent voice across a long document and pushes back instead of inventing achievements.
• The best AI for Excel & spreadsheets — Strong at formula syntax and at explaining what each part does, so you can fix it later yourself.
• The best AI for reading images — Handles screenshots, charts and photos cheaply enough to use them casually.
