In-Depth Analysis
ChatGPT
Advanced AI models for web, iOS, Android, and desktop
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
