ChatGPT vs Claude vs Gemini (2026): Models, Pricing and Which to Choose
Quick verdict

- ChatGPT is the broadest all-rounder, with built-in image generation, voice, agents and a coding tool.
- Claude is the one many writers and developers pick for long documents and coding work.
- Gemini makes the most sense if you already live in Gmail, Docs and Sheets.

The current models in October 2026
ChatGPT. Models: GPT-6 Astra (released Sept 3, 2026) is OpenAI's flagship. GPT-6 Sol and GPT-6 Luna (Sept 22, 2026) are the faster, cheaper tiers, rolled out in ChatGPT Work and Codex for paid plans, with Luna in the desktop app for Free and Go users. GPT-5.6 models remain available. Confirm exactly which model each plan gets on openai.com.
Claude. Anthropic's lineup is Opus 5.5 (released September 22, 2026) for the hardest tasks, Sonnet 5.5 (released September 28, 2026) as the everyday model, Haiku 4.5 as the small, fast option, and Fable 5.1 as its most capable generally available model. Opus is not on the Free plan. Fable 5.1 is reported to be included in Max, and available through usage credits on Pro.
Gemini. Google's current Pro model is Gemini 3.1 Pro, alongside a 3.x Flash line for faster, cheaper responses. Google has been changing which models free and entry-level accounts can use, with one report saying free accounts move to Flash-Lite from October 9, 2026. Confirm the current model access on Google's plan page.
Pricing and free plans
All three sell a roughly $20 plan, plus higher tiers for heavy use. On each, the higher tiers mainly buy more usage, not a different product.
- ChatGPT: Free, Go ($8), Plus ($20), and Pro from $100 per month. Sol and Luna roll out in Work and Codex, with Luna on Free and Go desktop apps; GPT-5.6 models remain available. Confirm exactly which model each plan gets on openai.com.
- Claude: Free, Pro ($20, or $17 billed annually), and Max at $100 or $200. Pro and Max add Opus 5.5.
- Gemini: Free, AI Plus (about $4.99), AI Pro ($19.99), and AI Ultra at $99.99 or $199.99.
If you only need an occasional chat assistant, all three free plans are enough to try. If you hit usage limits regularly, compare the $20 plans first before paying for a power tier.
Where each one fits
Writing and long documents. Claude is widely reported to be a strong choice for long-form writing and working across long documents. ChatGPT and Gemini are both capable here, so the best way to decide is to try the same task on each free plan.
Coding. All three have coding tools: Codex for ChatGPT, Claude Code for Claude, and Gemini's developer tools. Claude and ChatGPT are the two most often compared for developer work.
Research. All three offer deep research modes. Gemini's advantage is its link to Google's ecosystem.
Google Workspace. Gemini is built into Gmail, Docs and Sheets, which is its clearest advantage if your team already uses Google.
Images, voice and agents. ChatGPT has the widest set of built-in features, including image generation, voice and agent tools. Claude does not include a built-in image generator. Gemini offers image generation as part of its plans.
Things to keep in mind
- Model names and plan limits change often, so a model that is paid-only today may reach free plans later, and the reverse.
- Usage limits are not published as fixed numbers, so heavy users should read each vendor's current limits.
- Marketing names are confusing: ChatGPT now has more than one "Pro" tier, and Gemini has several plans with similar names.
Which should you pick?
- Choose ChatGPT if you want one assistant with the widest feature set, including images, voice and agents.
- Choose Claude if most of your work is writing, long documents or coding.
- Choose Gemini if your work happens in Gmail, Docs and Sheets.
- Not sure? Try the same real task on all three free plans before paying.
