Key features

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

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

- +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

Weaknesses

- -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
