In-Depth Analysis

ChatGPTChatGPT

Advanced AI models for web, iOS, Android, and desktop

Starts at Free · 4.5/5 from 4 reviews
Good value

The model split is the real product now, not the $20 sticker.

Watch out

Go does not unlock Sol. You are paying for limits, not the flagship model.

Strengths

  • +Free and Go now run a current-generation model, not a leftover model
  • +Unlimited everyday text on Free/Go (abuse guardrails). Think is there if the question is hard
  • +Plus folds Instant and Thinking into one model plus a slider, so you are not picking legacy names
  • +Pro offers enough usage to unlock the flagship model without paying the highest tier

Weaknesses

  • -Free and Go never get the advanced flagship model in standard chat. Think is still a standard model, not the flagship.
  • -The current rivals are advanced models. Older models are leftover API SKUs
  • -Standard and basic models are not in the regular chat picker. They live in Work, Codex, or the API
  • -Go, Plus, and Pro have no annual billing
  • -Older models leave Codex (ChatGPT login) soon; switch to the current models

Key features

GPT-5.6 Luna as the Free and Go chat default, plus a Think button (still Luna)GPT-5.6 Sol on paid chat with a reasoning slider (Instant, Medium, High, Extra High)GPT-5.6 Sol Pro on Pro (and Enterprise) for the hardest / longest jobsGPT-5.6 Terra in Work and Codex for Free/Go; Sol/Terra/Luna picker on Plus+Text, voice, and voice-with-video on web, iOS, Android, and desktopWeb search, file analysis, and image generation (tool caps still apply on Free/Go)
