Good value

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 Sol model plus a slider, so you are not picking legacy names
  • +Pro $100 is enough to unlock Sol Pro without paying $200

Weaknesses

  • -Free and Go never get the advanced Sol in standard chat. Think is still Luna, not Sol
  • -The current rivals are advanced models. Older models are leftover API SKUs
  • -Terra and Luna 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 Terra / Luna
