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
- Pro: Free and Go now run a current-generation model, not a leftover model
- Pro: Unlimited everyday text on Free/Go (abuse guardrails). Think is there if the question is hard
- Pro: Plus folds Instant and Thinking into one model plus a slider, so you are not picking legacy names
- Pro: Pro offers enough usage to unlock the flagship model without paying the highest tier
Weaknesses
- Con: Free and Go never get the advanced flagship model in standard chat. Think is still a standard model, not the flagship.
- Con: The current rivals are advanced models. Older models are leftover API SKUs
- Con: Standard and basic models are not in the regular chat picker. They live in Work, Codex, or the API
- Con: Go, Plus, and Pro have no annual billing
- Con: Older models leave Codex (ChatGPT login) soon; switch to the current models
Key features
Chemistry AI
Solve chemistry problems with step-by-step guidance
Chemistry AI is a freemium chemistry homework solver, not an unlimited free site.
Watch out
Free plan is 7 credits per month: Basic mode only, no Guided mode, no image upload.
Strengths
- Pro: Shows the working (givens, formulas, units), not only the final answer
- Pro: Chemistry-specific modes for balancing, stoichiometry, and intro organic
- Pro: Guided mode walks the problem in checkpoints instead of dumping the solution
- Pro: Paid plans accept worksheet photos, including messy handwriting
Weaknesses
- Con: Free plan has limited credits per month, Basic mode, no guided steps, no image upload
- Con: A free account is required to start; this is not an unlimited no-login solver
- Con: Does not replace an instructor for graded work or lab-safety decisions
- Con: Credit-metered: a conversation spends a credit, so heavy exam weeks need a paid plan
