The short verdict

Quick verdict

Pick Gemini if you want the cheaper paid entry point, bundled Google storage, or a tight fit with Google's apps. Pick ChatGPT if you want OpenAI's own toolset, such as custom GPTs, projects, scheduled tasks and Codex, on a plan around $20 a month. If you are unsure, both have a free plan, so run the same real task in each.

ToolNest did not run benchmarks or hands-on tests for this page. The comparison rests on what the vendors say officially about their plans, so it tells you what each plan is documented to include, not which one gives better answers on your work.

Google AI Ultra: from $99.99 a month for 5x AI Pro usage limits, or $199.99 a month for 20x, with storage from 20 TB. Google's Google One page says Ultra is billed monthly only.
Documented context window	Free 27K, Plus 54K (Instant models) and 256K (reasoning), Pro 128K and 400K. OpenAI says these are approximate and may change dynamically.	Free 32k, AI Plus 128k, AI Pro and Ultra 1 million tokens (Gemini Apps Help).
How limits work	Plan-based allowances that vary by feature; OpenAI lists "Limits apply" on Plus.	Usage is a multiple of Google's "standard limits". The limit refreshes every 5 hours until you reach a weekly limit, and Google says limits may change without notice.

Ads	ChatGPT's pricing page says Go "may include ads".

OpenAI said Plus, Pro, Business and Enterprise will remain ad-free (January 2026).	Google's plans page does not mention ads in the Gemini app.
Coding tools	Codex, included in limited form on Free and expanded on Plus.	Google AI Pro lists entry rate limits to an agent model in Google Antigravity.

Business, enterprise and API (not individual plans)

These are sold to organisations or developers, so they are kept out of the table above and should not be read as individual subscription prices.

ChatGPT (Business and Enterprise)

ChatGPT Business: $20 per user a month billed annually, or $25 billed monthly, minimum 2 users, per OpenAI's ChatGPT Work and Codex pricing documentation. ChatGPT Enterprise: enterprise agreement; OpenAI lists no price and says to contact sales. OpenAI says API token prices are separate from subscription usage.

Gemini (Workspace, Gemini Enterprise and API)

Google Workspace: Google's pricing page showed no dollar amounts when we read it. It lists Gemini in Workspace apps for the Standard, Plus and Enterprise tiers (limited on Starter), and caps Business plans at 300 users. Gemini Enterprise (a separate Google Cloud product): Business edition "Starting at $21 per seat per month" with a 30-day trial; Standard and Plus editions are sold through sales. The Gemini Developer API is priced per 1M tokens on a separate page and is not compared here.

Which one should you choose?

Choose ChatGPT if...

You want projects, scheduled tasks and custom GPTs. OpenAI lists all three on Plus.
You use Codex for coding. OpenAI lists limited Codex on Free and expanded Codex on Plus.
You want a path above Plus inside the same product. ChatGPT Pro offers three usage tiers (check current prices on OpenAI's pricing page).
You want to test deep research without paying. ChatGPT Free lists limited deep research, and Plus lists expanded deep research.

Choose Gemini if...

You want the cheapest paid plan. Google AI Plus is $4.99 a month in the US, against $8 for ChatGPT Go, and it includes 400 GB of storage.
You want cloud storage bundled with your AI plan. Google includes 15 GB on Free and up to 5 TB on AI Pro across Gmail, Drive and Photos.
You regularly work with very long inputs. Google documents a 1 million token context window on AI Pro and Ultra, the largest figure either company lists for its individual plans.
You live in Google's apps. Google's plan page lists "Access Gemini directly in Google apps" from AI Plus.

Trade-offs to know about

ChatGPT limitations

Limits vary by feature and plan, and OpenAI says limits apply even on paid tiers. Check the plan table before relying on any one capability.
Go may show ads, and Go is not available in every region.
Free is documented at 27K context for Instant models, which is small for long documents.
Pro comes in three usage tiers, and we could not confirm their consumer prices from ChatGPT's main pricing page.

Gemini limitations

Usage is a multiple of an unstated "standard" limit, so the absolute amount is not published, and Google says limits may change without notice.
Free is documented at a 32k context window and AI Plus at 128k, so the 1 million token window needs AI Pro.
Some features are limited to certain countries or tiers, and Google says Flow features vary by tier, platform and region.
The highest tier starts at $99.99 a month and is billed monthly only.

Frequently asked questions

At the entry level, yes in the US: Google AI Plus is $4.99 a month and ChatGPT Go is $8 a month. At the standard tier they are close: Google AI Pro is $19.99 a month and ChatGPT Plus is $20 a month. The bundles differ, because Google includes cloud storage and OpenAI does not list any on its plan page. Go is available only in select regions, and prices can vary by country and tax.

Google documents a 1 million token context window on Google AI Pro and Ultra, 128k on AI Plus and 32k on Free. OpenAI's pricing page lists 128K for Instant models and 400K for reasoning on Pro, and 54K and 256K on Plus. These figures depend on model and mode, and the pricing-page text we read did not state OpenAI's unit, so they are not a like-for-like comparison. ToolNest has not tested either, so try a real document before paying.

This page's table covers individual plans only. ChatGPT Business is priced per user, at $20 a month billed annually or $25 billed monthly with at least 2 users, according to OpenAI's ChatGPT Work and Codex pricing documentation. Google Workspace's pricing page showed no dollar amounts when we read it, though it lists Gemini in Workspace apps on its higher tiers. Gemini Enterprise Business edition is a separate product that starts at $21 per seat a month.
