With Go (₩13,000/month), ChatGPT now has four paid tiers. Go raises message and upload limits over Free, but Plus (₩29,000/month) unlocks full features like image generation, deep research, and coding agents. Pro (₩159,000/month) is for heavy pros. Billed in KRW.
AI Plus (₩7,500/month) offers the lowest barrier to entry and unlocks video generation. AI Pro bundles top models, 2TB Drive, expanded notebook limits, and Gmail/Docs integration. AI Ultra starts at ₩119,000/month. Check for student promotions before paying.
Pro ($20/month) gives 5x more usage than Free, plus Projects and Claude Code. One tier is enough for daily long-document workflows. Max ($100+/month) targets full-time developers. There is no image generation, so pair it with another tool if you need visuals.
SuperGrok ($30/month) raises limits for top models, images, and voice. It is also included with X Premium+. It suits those wanting real-time X data or an unfiltered tone, but pricing is high and professional use needs tone adjustments. Verify current plans first.
Choose a paid plan by identifying what hit a limit in the free tier. If you only need higher usage, cheaper tiers around ₩10,000 like ChatGPT Go or Gemini AI Plus often suffice. Pick ChatGPT Plus for image generation and deep research, or Claude Pro for long documents. Note currency differences (KRW vs. USD) and check student perks before subscribing.
