The Bottom Line
- Best for
- People who will stay on Luna for everyday chat, or pay $20 for Sol (or $100+ for Sol Pro)
- Price
- From $8/mo (free plan available). Compare plans
Key facts
- Free and Go run an advanced model, including Think mode.
- Free costs $0, Go offers paid tiers, Plus offers paid tiers, and Pro offers paid tiers. None of these four has annual billing.
- In Work and Codex, Free and Go get a standard model, while Plus and above choose among several models. The Team plan was replaced by Business.
Pros
- 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
Cons
- 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

Is ChatGPT worth the price?
The model split is the real product now, not the $20 sticker.
Free and Go run GPT-5.6 Luna: current-gen chat, no Sol. That is enough for everyday questions and a Think pass.
Plus at $20 is the first seat that chats on GPT-5.6 Sol and lets you move a reasoning slider. Pro is how you buy Sol Pro and more of it ($100 or $200).
Business is Sol plus admin, not a cheaper Plus. Do not buy Go expecting Sol.
Do not buy Plus expecting Sol Pro.
Hidden Costs & Gotchas
Go does not unlock Sol. You are paying for limits, not the flagship model.
Terra/Luna in Work and Codex are extra surfaces, not the main chat picker.
API tokens for Sol/Terra/Luna are a second bill. Codex ChatGPT-login drops GPT-5.4 on 31 Aug 2026.

Utility player AI that falls behind Claude for article creation
- Probably the best I've used at doing many tasks good to pretty well. It can do thought partnership, pivot to an image creation task, do deep research and attempt a joke to keep things light.
- The Projects feature is more useful than Gemini's version, and I see that Claude added that too. Once I figured it out I created a "Temp Chat" project that I always start a session in, then I move it to a project folder that aligns. Note: these are not "folders" per se, but a central theme that subsequent chats can pull from within that Project. There is a Chrome/Edge extension that does folders nicely if you need more granular organization of your work.
- The integrations with other software services work fairly well, although it's unclear how those activities use up capacity. This was a primary reason I purchased the Pro license. Like all things the other AIs are catching up, notably Claude.
- ChatGPT likes to turn simple answers into a more complex result. It will give a "1.0" answer and, as part of that answer, say "For 2.0 I would add...". Why wouldn't the 2.0 idea be part of the 1.0 suggestion?
- When writing drafts for social media posts, it likes to separate sentences out to create a false sense of importance. It does this so often that I've had to adjust memory settings a few times to try to stop it. When an update hits, the behavior starts again.
- It will shift recommendations within that micro-chat (prompt -> answer) session, inexplicably. When I point that out it always says something like "that's a fair observation". One time it gaslit me about an instance of that and I felt compelled to paste a screen capture to prove my point.
- It, way too much, wants to please the user. Not sure how to fix this tbh.
- All of the above take up more time and focus than they should.
