Heavy creative and agent users.

Which plan to pickStart free. If you're putting anything sensitive in or building something people will use, switch to a paid API key so your prompts aren't used for training. Google AI Pro only makes sense if you'd use the Gemini app upgrade too.Skip the free plan for anything serious now that it's Flash-Lite only. AI Pro (US$19.99, or A$32.99 in Australia) is the one to buy: it's the cheapest way to get Gemini 4 Argon plus Gemini in Docs and Gmail, and the 5 TB of storage offsets a Google One bill. Ultra is for people generating video all day.There's nothing to buy. Use it free, and pay for whichever assistant comes out best for your work.

Pros and cons

AttributeGoogle AI StudioGoogle GeminiLMArena
Pros
  • Free access to Google's Flash models with full control over settings
  • Build mode turns a description into a working, publishable app
  • Handles very long documents, audio and video
  • The quickest way to get a Gemini API key
  • Reads and acts on your Gmail, Docs and Drive directly
  • AI Pro bundles the top model, Workspace features and 5 TB of storage for one price
  • Deep Research is included even on the free plan
  • Fast, and the mobile and Android experience is polished
  • Video and image generation included on paid plans
  • Desktop apps for Windows and Mac as well as the web
  • Free access to the leading models, often before release
  • Blind voting makes it easy to judge models on output alone
  • Leaderboards cover text, code, images, video and agents
  • Real people's preferences are harder to game than lab benchmarks
Cons
  • Free-tier prompts may be used to improve Google's products and reviewed by people
  • Daily limits are unpublished and users report them being cut, including for paying Pro subscribers
  • Confusing for non-developers, and it overlaps with the Gemini app and Antigravity
  • Gemini 4 Argon and Veo video need a paid plan or API billing
  • The site can be buggy and slow on long chats
  • Free plan is now Flash-Lite only, so it's weaker than the free tiers of ChatGPT or Claude
  • Plan names and model access keep changing, which is confusing
  • Writing quality sits behind Claude and the answers can be padded
  • Workspace features need a personal Google account or a Workspace admin to turn them on
  • Usage resets every 5 hours up to a weekly cap, and Google doesn't publish the numbers
  • Rankings favour answers that look good, and labs have been caught testing private versions to climb the board
  • Conversations are collected and partly shared with model makers, so keep private work out
  • Frequent "something went wrong" errors, captchas, logouts and models removed without notice
  • Direct chat is being narrowed, with newer models only available in random battles
  • The company now sells evaluations to the labs it ranks, which raises questions about neutrality
