OpenAI announced ChatGPT Go, a new subscription tier positioned between the free offering and ChatGPT Plus, now available worldwide [source]. The tier provides access to GPT-4o with higher message limits than free users receive, though lower than Plus subscribers.

ChatGPT Go is priced at $9 per month in the United States, compared to $20 for Plus. The company states the tier is designed for users who need more capacity than the free version but do not require the full feature set of Plus, including advanced voice mode, DALL-E image generation, or priority access during peak times.

The announcement follows OpenAI's December 2024 introduction of the $200-per-month ChatGPT Pro tier, creating a four-tier structure: free, Go, Plus, and Pro. OpenAI has not disclosed specific message limits for Go users, stating only that limits are "higher" than free tier allocations.

Industry observers note the move mirrors pricing strategies in consumer software markets, where mid-tier offerings capture users unwilling to commit to premium subscriptions. OpenAI's revenue model has shifted toward subscriptions since launching Plus in February 2023, with the company reportedly targeting $5 billion in annual revenue by end of 2024.

The Go tier does not include access to OpenAI's o1 reasoning models or custom GPT creation tools, features reserved for Plus and Pro subscribers. Free users retain access to GPT-4o but face stricter rate limits, which OpenAI adjusts based on demand without public documentation.

ChatGPT Go became available January 16, 2025, with rollout across all regions where ChatGPT operates. Existing Plus subscribers are not affected by the new tier structure.
